Critique of Evan Harris Walker’s Letter in Physics Today, February 1991


by Allen Esterson


In the February 1991 issue of Physics Today Evan Harris Walker responded to a letter published by John Stachel in reply to one by Walker in the February 1989 issue of Physics Today. What follows is a critical examination of Walker’s February 1991 letter, taken point by point.[1]


John Stachel stated in his February 1989 letter to Physics Today that, aside from one comment on a course she took, “none of Marić’s letters to Einstein touches on any substantive point in physics, while his to her are chock-full of substantive comments on books and articles in physics…” and that “one could not select ten of Einstein’s letters to Marić that would be as devoid of references to physics as are hers to him”. Walker retorts that in this “Stachel is wrong. Eleven of Einstein’s letters to Mileva have no reference to science at all…” Now while Walker is correct in his statement, three of the eleven letters cited by Walker do in fact have a brief reference to physics, and three of them are mere notes. (Documents 40 and 41 refer to a volume by the physicist Paul Drude that Einstein is reading,[2] and document 68 has a passing reference to a book by the physicist Rudolf Kirchhoff.)[3] Nevertheless, Walker is correct insofar as that more than ten letters of Einstein’s have no reference to physics, or only a passing citing of a physics volume or allusion to their coursework at Zurich Polytechnic of the kind that also occurs in some of Marić’s letters to Einstein. This does not alter the essential picture that Stachel is emphasizing: that in nearly two-thirds of Einstein’s 43 letters he writes of his ideas on topics outside the curriculum or refers to books or papers dealing with such topics, contrasting strongly with the lack of such items in Marić’s letters, which are dominated by references to personal matters. (Of the eight other Einstein letters that Walker correctly states have only a single brief reference to science, seven allude to extra-curricular studies of his, whereas of the four Marić letters he cites as equivalent, three of the brief references are to Einstein's extra-curricular activities, and the remaining one is a brief report of a lecture on the kinetic theory of gases she attended at Heidelberg University in the winter semester 1897-1898.)


Whereas Stachel is right when he observes that there is nothing in any surviving letter of Marić’s remotely comparable to the substantive material on his own ideas to be found frequently in Einstein’s, Walker goes wrong as soon as he starts to infer what was in the many letters of Marić’s that have not survived. He writes: “To determine what Marić’s letters likely contained, we must…examine Einstein’s letters to her. It happens by doing so we can tell that many of her lost letters make reference to her scientific work, to her comments on science and to their collaborative efforts. I find statements in 13 of his 43 letters to her [references given] that refer to her research or to ongoing collaborative effort – for example, in document 74, ‘another method which has similarities with yours’.”


First it should be noted that in document 74 that Walker cites, Einstein is referring to Marić’s dissertation on heat conduction originally produced for the 1900 final diploma examinations which she hoped to develop into a doctoral thesis (discontinued in October/November 1901).[4] This also applies to Walker’s citing Einstein’s writing “I am also looking forward very much to our new work. You must now continue with your investigation” in the following letter (document 75). The second sentence continues: “how proud I will be when maybe I’ll have a little doctor for a sweetheart while I am myself still a totally ordinary man”. The research in question, as is evident from Einstein’s previous letter, again relates to her dissertation on heat conduction, not to the kind of extra-curricular ideas that Einstein frequently writes about, which were to culminate in papers published in the next few years.


The rest of Walker’s case in connection with the Einstein-Marić correspondence concerns Einstein’s occasional use of inclusive language (“our” and “we”) in regard to his ongoing extra-curricular studies. This line of argument has been amply refuted by Stachel,[5] and here I shall only make a few brief points.


Walker does not cite the numerous occasions that Einstein uses first person singular pronouns (“I” and “my”) with respect to the very same work in regard to which he uses first person plural pronouns on one or two occasions. For instance, later in the year (1901) in which he referred to “our work on relative motion” he told Marić:  “I’m busily at work on an electrodynamics of moving bodies, which promises to be quite a capital piece of work.” (At this stage he was still working with classical (Galilean) relative motion. This was some four years before he wrote the 1905 paper incorporating his crucial special relativity principle that eliminated the concept of the ether.) Again, there are letters that Marić writes to her friend Helene Kaufler in which she unambiguously attributes to Einstein papers on topics in regard to which he had on occasion used inclusive language.[6] In two of these letters she writes “how proud I am of my darling” in relation to his first published paper, and of the “real admiration” she has for the first submitted attempt at a doctoral thesis by Einstein, “who has such a clever head”.[7] These are not the words of someone who has collaborated in Einstein’s research.


Walker’s contention that it can be inferred from Einstein’s letters that the lost letters by Marić contain reference to her scientific work is only true with regard to her diploma studies, and more specifically, to their prospective doctoral dissertations. There is no evidence of significant collaboration by Marić in his extra-curricular writings beyond joint reading of books and occasional help in locating material when they were students. The comments in Einstein’s letters relating to his extra-curricular research on physics indicate his wish to communicate his current ideas to an interested listener, and provide no evidence at all of responses in kind. As he wrote on 10 April 1901: "So today I am going to give you a detailed report of what I am up to, because I see that you enjoy it." (In the two instances where we have letters of Marić’s responding directly to ones of Einstein’s containing such material, she makes no mention whatever of the ideas he had written about.)[8]


As Stachel argues, the inclusive language used by Einstein at certain times reflects his desire for a joint life together devoted to physics, whereas the indications that published work was solely Einstein’s, and the complete absence of any document containing ideas of Marić’s on physics, are not consistent with the notion of her making any substantive contribution to his 1905 papers.[9]


Presumably to buttress the notion that Einstein could not have been capable of his later achievements without the assistance of Marić, Walker writes in relation to Einstein’s record at the Zurich Polytechnic:


In 1895 Einstein failed his first try at the entrance examinations for the ETH [formerly Zurich Polytechnic]. Though Einstein did well in the intermediate examination in 1898, by 1899 he was having difficulties. In March 1899 he received the ‘director’s reprimand for nondiligence in physics practicum.’ By 1900 Einstein’s grades were down. Albert passed with a questionable 4.91, trailing well behind Jakob Ehrat, Marcel Grossman and Louis Kollros, whom he had previously led. [Citations omitted]


In this passage Walker tendentiously omits facts that cast a completely different light on the situation. Prior to Einstein’s first attempt at the entrance examination for Zurich Polytechnic he had living in Italy with his parents for some eight months without formal schooling. Moreover, he was only 16 at the time, and as he was about eighteen months below the stipulated age of 18 he had to obtain special permission to take the exam. He failed to achieve the required standard in languages and some other subjects, but his results in mathematics and physics were excellent, so much so that the physics professor Heinrich Weber invited him to audit his second year classes. On the advice of the Principal of the Polytechnic he attended high school in Aarau in Switzerland to cover the gaps in his knowledge. His school-leaving certificate the following year records that he achieved maximum grades in algebra and geometry, high grades in physics and chemistry and some other subjects, and performed badly only in French. In the Matura (university entrance level examinations) that he took in September 1900 he gained the highest grade average of the eleven candidates.[10]


Walker writes that Einstein did well in the intermediate diploma examinations; in fact he obtained the highest overall grade of the six candidates. (Marić's grade for the intermediate exam, which she took a year later than normal because of a winter 1897-1898 semester spent auditing a course at Heidelberg University, was the lowest of the original  group.) It is true that he fared less well at the final diploma examination in 1900, but during the previous two years he had become more engrossed with following up his own interests in physics, and neglected his college studies (hence the reprimand for poor attendance on one course cited by Walker). He borrowed the meticulous notes of his friend Marcel Grossman for some subjects to enable him to revise for the final examination, and achieved a creditable overall grade of 4.91 (scale from 1-6). In not one of the four physics topics examined did he achieve less than 5; it was his grade of only 4.5 in the heavily weighted dissertation that brought his overall grade average down below 5.


Walker writes that Einstein’s “questionable 4.91 average” trailed “well behind” the other students who passed the examination. In fact the difference between Einstein's grade average in the final diploma exams and that of the candidate immediately above was only 0.23, (it was 0.54 below the top student's grade average), so he hardly trailed well behind the others. (By comparison, Marić's grade average was 0.91 below Einstein's.)[11]


Walker’s efforts to demonstrate that Einstein “barely satisfied the requirements for the degree” (actually a teaching diploma) can only be in the interests of indicating that his talents were not exceptional enough to explain his achievements except by presuming that he had had the assistance of Marić. (He writes that Einstein’s work was “no longer filled with daring concepts” after he separated from Marić in 1914.) This is absurd on two counts. First, though Einstein’s academic record at the Polytechnic (as against his extra-curricular research) was relatively modest, Marić’s was consistently worse, and she failed the diploma examination. If the argument is that Einstein’s record in some way precludes the possibility that he could have produced the celebrated 1905 papers without assistance, then one would have to look elsewhere than to Marić for that help. Second, Einstein’s communications with first-rate physicists in the years following the 1905 publications show unequivocally that he was more than equal to the role of one of the pre-eminent physicists of his day, and his stature was recognized by physicists of the calibre of Planck, Lorentz, Nernst, Sommerfeld, Born, Bohr, and many others.


In relation to the question of Einstein’s knowledge of the famous Michelson-Morley experiment that was of relevance to the 1905 special relativity paper, Walker writes:


…a careful reading of those [Einstein/Marić] letters shows only that Marić and Einstein between them had that knowledge [of the experiment]. All the references that Stachel quotes to show that Einstein should have known of the Michelson-­Morley experiment and been familiar with Hendrik Antoon Lorentz’s work are taken from Albert's letters to Marić, and not from any of the other 99 documents in the first volume of the Collected Papers. The fact that we now know that Mileva and Albert between them had available the cru­cial information about the Michel­son‑Morley experiment and informa­tion about Lorentz’s work, while at the same time we know that Einstein later professed little knowledge of these, suggests that Mileva supplied this information and she therefore was as capable of discovering the principles of special relativity as her husband!


Where does one begin to counter such contorted logic? The letters in question are all written by Einstein, so it is he who had read the relevant works. (To what extent Marić also studied them is impossible to judge, as her surviving letters make no mention of any ideas she has on the topics  in question – or indeed of any extra-curricular topics in physics.) That Einstein’s much later recollections about when he learned of the Michelson-Morley experiment were apparently faulty hardly constitutes evidence that it must have been Marić who supplied this information. The information, after all, came from articles or books, and it was Einstein who mentioned these, and he alone who wrote about matters relating to his own extra-curricular interests, such as motion relative to the ether, in their correspondence. Walker’s arguing that, on the evidence-free assumption that it was she who was first aware of the Michelson-Morley experiment, Marić was just as capable of discovering the principles of special relativity is more than a little absurd. How could knowledge of this one experimental result indicate the capability of arriving at the principles of special relativity? Many physicists and some University students would have read of the experiment, but that didn’t mean they were capable of arriving at the ideas incorporated in Einstein’s special relativity paper that he produced in 1905. And in any case, the experiment was but one strand in his thinking that led to the development of the special theory or relativity.[12] Furthermore, Walker evades not only that there is not a single known document of Marić’s in which she provides original ideas of her own, but also that she failed her teaching diploma exam (with especially poor results in the mathematics component, with less than half the grade of the other five candidates).


Incidentally, Walker’s reference to “the other 99 documents in the first volume of the Collected Papers” is a red herring. Scarcely any of these other documents are of a nature that they might have contained information about the Michelson-Morley experiment.


On the basis of his dubious arguments Walker concludes that “Mileva Marić deserved to be a co-author” of the relativity paper. Indeed, he writes, her name did appear on the original manuscript of the paper! As evidence for this he provides a quotation from a biography of Mileva Marić by Desanka Trbuhović-Gjurić in which the author claims that the Soviet physicist Abraham Joffe “called attention to the fact that Einstein’s three epoch-making articles of 1905 were marked in the original ‘Einstein-Marić’. According to Trbuhović, “Joffe as an assistant to Roentgen, who belonged to the board of trustees of the Annalen der Physik, had seen the originals that the editor had forwarded for review. To this work Roentgen pulled in his summa cum laude student Joffe, who had the opportunity to see the manuscripts that are no longer available today.”


These claims have been refuted by Alberto Martínez and, in meticulous detail, by John Stachel.[13] In the obituary in question Joffe writes of the 1905 papers that they were written by “a bureaucrat at the Patent Office in Bern, Einstein-Marity (Marity – the last name of his wife, which by Swiss custom is added to the last name of the husband)” – in other words, Albert Einstein. There is no suggestion that the articles were co-authored. The statement made by Trbuhović concerning Roentgen is nothing but surmise on her part, based on the erroneous misconception that Joffe had claimed to have seen the original manuscripts, which he did not. In any case, as Stachel points out, “Roentgen was an experimentalist, and there is no reason why a purely theoretical paper should have been submitted to him for review when two members of the Curatorium [of Annalen der Physik], Paul Drude (the editor) and Max Planck, were both outstanding theorists quite capable of evaluating the paper.”[14]


Walker acknowledges that Joffe’s reference to the 1905 papers cited a single author, but finds a way of maintaining nevertheless that the papers must have been co-authored. He writes that “Joffe’s use of ‘Einstein-Mariti’ [in Cyrillic script] agrees with Mileva’s adoption of the Hungarianized spelling of her Serbian name Marić, a fact that Joffe would only have known had he seen the original signed by her, since this usage of “Mariti” apparently is not found in any of the Einstein biographies.” I’ll leave to Martínez the refutation of this claim, along with the others:


As for the article ‘In remembrance of Albert Einstein’, published in 1955, it was an obituary for Einstein. Literally translated, it reads:


In the year 1905, in Annals of Physics , there appeared three articles, thereupon beginning three most important, relevant directions in the physics of the 20th century. Those were: the theory of Brownian motion, the photon theory of light and the theory of relativity. Their author – unknown until that time, a bureaucrat at the Patent Office in Bern, Einstein-Marity (Marity – the last name of his wife, which by Swiss custom is added to the last name of the husband). (Joffe, 1955: 187, trans. A. M.)


This passage shows that, for example, Walker’s ‘translation’ is a gross misrepresentation: ‘Their author was “Einstein-Mariti”.’ Likewise, a few other writers have distorted Joffe’s words to make it seem as though he made a controversial claim. It is unusual that Joffe this one time happened to refer to Einstein by the name ‘Einstein-Marity’. But that simple peculiarity does not entail that he ascribed any authorship to Einstein’s wife. It is clear that Joffe meant that the author was one person, a male employee at the patent office, namely Albert Einstein.


Still, proponents of Marić have tried to make something out of the fact that Joffe happened to write ‘Marity’ instead of ‘Marić’. For example, Walker claimed that Joffe just had to have seen an original paper, with the name Marity on it, because otherwise he would not have known the alternative spelling of Marić, since it ‘apparently is not found in any of the Einstein biographies’ (Walker, 1991: 123). Again, Walker was wrong. The name ‘Marity’ appears, for example, in Carl Seelig’s well-known biography of Einstein published in 1954 (p. 29). Moreover, when Joffe first sought to meet Einstein in Switzerland, he happened to meet Marić (Joffe, 1967: 889). At the time, she used the name Einstein-Marity.


The key point remains the same. Joffe did not claim that Marić co-authored or collaborated in any of Einstein’s papers. And he did not claim that her name was on the original manuscripts or that he ever saw any such manuscripts. In multiple places throughout his career, like anyone else, Joffe acknowledged Einstein for having authored the famous works of 1905.[15]


This demonstrates that, as with his other claims to have provided evidence that Marić should be regarded as co-author of Einstein’s celebrated 1905 papers, in his February 1991 letter to Physics Today Walker is engaging in a combination of clutching at straws and wishful thinking.




Up to at least November 2005 Walker had a personal website which included a webpage with the title “Evan Harris Walker looks at Albert Einstein & Mileva Maric”:


The webpage has not been available since early in 2006, and now access by means of the Archive retrieval Wayback Machine website “has been blocked by the site owner”.* However, it is of interest to examine some of the claims originally made there by Walker.


1. Abraham Joffe tells us that he saw the original relativity manuscript ‘and the name on this paper was Einstein-Marity’.


This is false. Joffe did not state that he had seen the original manuscript. (See above.)


2. The Special Theory of Relativity began as a thesis Mileva wrote and submitted to Professor Weber, her major professor at the ETH [Zurich Institute of Technology] in Switzerland. Weber rejected the paper.


This statement so inhabits the realms of fantasy that it is difficult to disentangle it in such a way as to make any sense of it.  Marić had to write a dissertation for her 1900 diploma examination at Zurich Polytechnic, and, as she told her friend Helene Kaufler, she hoped to write a Ph.D. thesis on the same topic (Popović, 2003, p. 56). The topic in question involved experimental studies of heat conduction (Stachel, 2002, p. 45; Renn & Schulmann, 1992, pp. 30, 32, 88, n.5 [Letter 20]). Marić gave up hopes of working for a Ph.D. not long after she failed the diploma exam for the second time in 1901 (Popović, 2003, p. 78), so there was no thesis that Marić submitted to Weber which he rejected. In any case the topics of her diploma dissertations were completely unrelated to relativity theory (which subject is never mentioned in any existing documents written by her).


So what is Walker writing about? There is a clue in his letter published in Physics Today in February 1989, where he writes that “Mileva never completed a thesis – at least not one that carried her name.” Now he cannot be alluding to her diploma dissertation, which she completed for the 1900 Zurich Polytechnic diploma exams, or the prospective doctoral dissertation which she aborted. The implication of his writing “at least not one that carried her name” can only be that she was wholly or largely the author of a thesis of Einstein’s. Einstein started to work on a thesis under the supervision of Weber in late 1900 (CP Vol. 1, [Eng. trans.], 1987, p. 154), but this came to nothing, presumably because of his falling out with Weber in the Spring of 1901 (Renn & Schulmann, 1992, p. 39). The topic of the proposed thesis was evidently related to thermoelectricity (Renn & Schulmann, 1992, p. 30). In 1901 he worked with Prof Alfred Kleiner of Zurich University as his supervisor on a thesis on the kinetic theory of gases (CP Vol. 1, [Eng. trans.], 1987, p. 188) which he submitted in November 1901 (CP Vol. 1, p. 190). Of the thesis Marić wrote to Helene Kaufler in December 1901: “Albert has written a magnificent study, which he has submitted as his dissertation…” (Popović, 2003, pp. 79-80). However Kleiner was evidently dissatisfied with the thesis, and Einstein formally withdrew it early in 1901 (CP Vol. 1, p. 190). (He eventually submitted a thesis on an entirely different topic to Kleiner in 1905, and obtained his Ph.D. in January 1906.)


It is evident that Walker’s claim that the Special Theory or Relativity originated in a thesis written by Marić and submitted to Weber at Zurich Polytechnic is pure fantasy.


3. The Photoelectric Effect paper began with Mileva Maric when she was a student of Professor Lenard at Heidleberg. In 1905 Professor Lenard received the Nobel Prize in physics for his experimental work on the photoelectric effect, the same year the theory of the photoelectric effect appeared under the name Einstein. In 1922, Albert Einstein received the Nobel Prize in physics for the theory of the photoelectric effect and in accordance with the terms of their divorce decree, he turned over every krona, every pfennig of the Nobel Prize money to Mileva Maric.


Walker’s claim that Einstein’s 1905 paper on the photoelectric effect owes its origins to Marić’s attending Lenard’s classes at Heidelberg University (in 1897) is again in the realms of fantasy.  We know precisely when Einstein first came upon Lenard’s first experimental results on the photoelectric effect, reported in a letter to Marić in May 1901 (Renn & Schulmann, 1992, p. 54). The experimental results that Einstein explained in terms of quanta in his celebrated 1905 paper were published by Lenard in 1902. Any connection between Marić’s attending Lenard’s course in Heidelberg in 1897-1898 and the 1905 paper exists entirely in Walker’s imagination.


Walker insinuates that the terms of the divorce agreement relating to the Nobel Prize money were directly connected to the authorship of the 1905 paper on the photoelectric effect. In fact Einstein did not "turn over every krona, every pfennig" to Marić.  By the terms of the divorce agreement the Nobel Prize money was deposited in a Swiss bank trust fund in Marić's name, but she could only use it with Einstein's permission, while she could freely draw on the interest. In the event of her death or remarriage, the money would go to their two sons. Einstein's originally proposal to relinquish the Nobel Prize money was made in a letter dated 31 January 1918 to overcome Marić's reluctance to agree to a divorce. (Collected Papers Vol. 8, docs. 449, 562.)


4. The Brownian Motion work came out of the mind of Albert and from his consuming interest in thermodynamics. Mileva contributed to the mathematics describing molecular random walk. This mathematics was critical to the experimental work of the French scientist Jean-Baptiste Perrin confirming the kinetic theory and showing the existence of atoms.


Nowhere has Walker ever provided a scrap of evidence that Marić contributed to the mathematics used by Einstein in his 1905 paper on Brownian Motion. Einstein was highly proficient at conventional mathematics, and would not have needed any assistance on the mathematics required for that paper.** On the other hand, in the mathematics component of the 1900 diploma exam at Zurich Polytechnic (theory of functions) Marić achieved a very poor grade 2.5 (scale 1-6) (None of the other candidates scored less than 5.5, which was the grade gained by Einstein.) (Collected Papers, vol. 1, doc. 67.)




Walker’s assertions quoted above serve to confirm Stachel’s remark to the effect that on the issue of Marić’s alleged contributions to Einstein’s work Walker “is a fantasist, who judges reality on the basis of his own desires” (Stachel, 2002, p. 26).


* Evan Harris Walker died on 17 August 2006.


** In the “Expert Opinion” on Einstein’s Ph.D. dissertation submitted to Zurich University in 1905, the physicist Prof Alfred Kleiner wrote: “The arguments and calculations to be carried out are among the most difficult ones in hydrodynamics, and only a person possessing perspicacity and training in the handling of mathematical and physical problems could dare to tackle them.” The mathematician Prof Heinrich Burkhardt, who was requested by Kleiner to give his expert opinion, wrote that “the manner and treatment demonstrates a thorough command of the mathematical methods involved”.
