Walther May (1868-1926), Freethinker, Socialist, Zoologist and Historian of Darwinism
by
Gaston Mayer, Karlsruhe*

Freethinker, socialist, zoologist, and historian of Darwinism, these are the stations of the life, clouded by tragic, of the professor of zoology at the technical college/university of Karlsruhe, Dr. Walther May (1868-1926). He detailed his career/development himself in a biographical sketch (1904, see here), so that the following only took the basic facts from it complemented through other sources for the time reported as well as for his later years.
    Walther Viktor May was born on 12.6.1868 in Marburg as son of captain Alexis Ferdinand Conrad May (1835-1870), who fell at Gravelotte, and of Elisabeth Karoline Walther (1842-1922).[1] He entered junior high school in Kassel on Michaelis 1878 (29 Sept) where he soon got into natural sciences and especially into Darwinism. He corresponded with Ernst Haeckel as a 16 year old already, in order to quench his thirst for knowledge. The liberal ideas of the French revolution also attracted him mightily. As a pupil he already published essays in various periodicals during the years 1886 to 1889 and a book "Statement of Beliefs of a Truth-seeker," wherein he summarized his freethinking and socialist views. After the end of his schooldays, Easter 1889, he went to Leipzig on 20 April, in order to study natural sciences at the university.Filled with the teachings of Darwin and Haeckel but also of Marx and Engels, he tried to spread thee with juvenile enthusiasm and found an opportunity in the newly founded freethinker club/union "Humboldt," which was largely supported by laborers, and became its chairman. The university's own court, however, forbade him this activity and also visiting any worker assemblies/gatherings, and it punished him with 4 days detention room [Karzer]. When he trespassed the prohibition thereafter and tried to talk about the world's creation and end, he got expelled from Leipzig university and relegated from visiting any other German university as well. Now he was "a free man," as he wrote himself, and wandered through Saxony from town to town, and he talked about Monism, Darwinism and Socialism. He reached Chemnitz on the 22.10.1891 and became editor of the social-democratic journal "Die Presse." As such he got into conflict with the press-law. He was accused of having justified theft from need/poverty and incriminated him

for blasphemy, abusing religion, and calling for disobeying the law. The court sentenced him in three cases to 12, 9 and 6 months prison in February and March 1892. These were contracted to a total punishment of 1 year and 10 months. He got detained and began his prison sentence on 4 March in jailhouse of Zwickau. Besides reading astronomical writings, he used the loneliness of the prison cell for studying the works of and about Goethe, whose objectivity and world view induced him [pronoun in accusative: ihn] to emulate him [pronoun in dative: ihm], to abdicate Schwärmerei, to desist further agitation and, "after one and a half year of inner wrestling," to write a letter of cancellation to the socialist party, which earned him spiteful opinions from former fellow party-members.[2] He wrote in defense: "I also now see clearly that I formed my political convictions at an age where I had neither the knowledge nor the life-experiences that are absolutely necessary, in order to judge and draw conclusions on the difficult sociopolitical questions." And in his autobiographic sketch we read: "Goethe broke my combative nature and turned me from a fighter and hotspur into a quietist and skeptic."
    After his disimprisonment he went to his mother in Kassel, where he arrived on 6 Jan 1894. On 2 April he went to Berlin taking up a job as a corrector in the print shop of his uncle, the publisher Hermann Walther (1850-1896). He did not find the work agreeable and sought recreation and edification on Sundays in Tegel (North of Berlin) at the memorial places for the esteemed Alexander von Humboldt, with whose person and work he engaged himself in detail. After gum bleeding already signaled a beginning lead-poisoning, a lucky change of his fate prefigured. He gave a presentation about Goethe's naturalist research and its relation to Humboldt, Darwin and Haeckel in his uncle's house. This prompted his uncle to write to Haeckel in Jena and ask him for counsel on how to help his nephew. Haeckel visited Berlin in September 1894 and promised to render May's resumption of his studies possible and to grant a stipend to him. May was overjoyed and could begin his studies in zoology, botany and mineralogy in the winter session of 1895 (26 Oct). Haeckel awarded him the Mende-stipend from Easter 1896 to autumn 1898, which supported hi with 600 Marks annually. May passed his exams summa cum laude on 8. May. He received a doctorate (Dr. Phil.) on 14.11.1898, for a work on the East-African Alcyonaceae [soft corals] in the [natural history] museum of Hamburg collected by Dr. Stuhlmann in 1889. During this work he traveled to Bergen (Norway) for 2 months, as an awardee of a scholarship of the Paul-von-Ritter foundation, in order to compare his material with the specimens kept in Bergen and in order to collect for the zoological institute of Jena. In October 1898, he found employment as a junior assistant at the station for plant protection in Hamburg checking imported plants for scale insect infestations. Two small works resulted from these examinations. He also worked on an exhibition of the collection of crustaceans of the natural history museum [Hamburg]. He had already worked for the museum while still in Jena [as part of his Ph.D.] by dealing with its East-African Alyonaceae together with the material of the museum in Berlin [? ... maybe Berlin should be Bergen] and the Alcyonaria of the Magalhaensian Collection Voyage [the results of this expedition were published as: "Ergebnisse der Hamburger Magalhaensischen Sammelreise," Vol. 1-3]. The farewell from Jena "the cozy idyllic nest" was hard for May. Studying the works of Darwin that he could obtain consoled him during the hazy winter days he had to pass in the metropolis.

[p. 485]
    This work ended in April 1899, after he could take up a post as an assistant of the forest zoologist Otto Nüsslin (1850-1915) at the Zoological Institute of the technical/polytechnic college/university in Karlsruhe. During that period (until the end of 1901) he also was the assistant [Hilftassistent] for the natural history collection of the zoological department, where he maintained the insect collection. In MArch of that year, he habilitated for zoology with a teaching assignment as a private lecturer [Privatdozent/ associate professor] for the forest zoology of mammals and birds, in particular. And he gave lecture/seminar/tutorial on Darwin's Life and Work. He submitted his habilitation treatise "Die arktische, subarktische und subantarktische Alcyonaceenfauna" [The arctic, subarctic and sub-antarctic fauna of Alcyonaceae] on 25 May. Prof. Kükenthal[3] judged this work on Alcyonacee in a letter to Prof. Nüsslin on 31 Jan 1902 as follows:
"It is not up to me [I am not competent enough in order to know whether] to count this work of May as one of the best that has been published in recent years among the literature on corrals. The description of the forms are exact, as I could convince myself though examinations afterwards [after reading May]. These works are especially valuable, however, because of the open perspective of the author and his ability to derive general conclusions from the found specific facts. The literary ability of Dr. May is beyond question and his special peers will be glad if he could continue to be active in this line of science."  
    He spent some weeks of the autumn holidays (August-September) in Rovigno in order to collect for the institute, wherefore a bursary/stipend/funding had been granted. And in the summer of the next year he traveled to England visiting London, Down, Cambridge, Lichfield, Derby and Shrewsbury on the traces of Darwin. In 1903, he held three talks for the public in Pforzheim on the theory of Darwin, the first on 6 January. Further talks on Darwin and Haeckel followed in February of the next year.
    May found a warm-hearted patron and friend in Nüsslin, who pleaded for him with the administration and colleagues, in order to reduce prejudices against his "criminal" past and to pave the way for his future. Nüsslin described these difficulties in a letter to Haeckel on 26.07.1903 as follows:
"The great interest that you maintain in your former students gives me the hope that you will receive the following lines kindly, as they concern the sorely "tried" Walther May. I, indeed, have some scruples concerning May. I am not sure whether the development he is now going through is the most desirable for him. After all he is my assistant and I am responsible for his zoological education to some extent.
    There can only be a limited area of zoology for him in Karlsruhe, that of applied zoology.He now reads forest zoology of mammals and birds, where the life of the animals is the main issue, of course. He takes no pleasure in my newer researches on plant-lice, which provide so many points of contact to fundamental/basic zoology and contain difficult problems/issues. Neither in histological or anatomical works. Even less he will learn to study the life and goings-on of animals in the wild outside. I repeatedly called his attention to the voices of our birds, but I doubt that he managed to distinguish blackbirds from thrushes by their song. His skill lies in a different area.
    I paved his ways here out of interest in his career and esteem for his striving, also out of sympathy for the whole person. I initially arranged that he can show his eloquence in the Natrurw. Verein and to impress his colleagues in that way. I then pushed and carried through his habilitation. Fortunately, the minister of state, Nokk,[4] still lived back then, permeated, as he was, with the spirit of Goethe. To him [Nokk] I presented his [May's]

past and received his consent in the habilitation in turn.Thereafter, it was not very hard to also overcome the difficulties within the senate that were not very grace anyway. The colleagues here are far more liberal in these matters than in the old university. They showed a warm interest in May.
    I arranged that he be consigned for the zootomic course and the forest zoology of mammals and birds and he receives 700 Marks for these teaching assignments. furthermore, I procured the 2-hour course for presentations/talks/lectures on general scientific subjects in the summer and winter session. HE lectured on evolutionary theory this summer and on exploratory voyages concerning the geographical sciences last winter. He receives 800 Marks for these. His position as an assistant earns him about 3000 Marks. As pleasant as it is to have achieved so much in three years, both in pecuniary matters and in the widening sphere of influence, it is not a life for good/long term. He does not advance zoologically in this way. His talks consume so much time[5] that even his ironclad diligence cannot find any free minute for research in the institute.   
    In my opinion, there are only two alternatives, either to step out of the previous or to stop continuing the apprenticeship as a "zoologist" according to the traditional habit, because May cannot become a "zoologist" in this way, neither for a university nor for an institute of forestry.
    If he was to step out of his previous career, this would be hard for May and only be possible with the help/interest of one of his previous teachers, who could provide a livelihood as an assistant for him. 
    If, as he seems to like best, he refrained from becoming a "zoologist" as a researcher in the common sense, that is, refrain from any position as a later professor, he could earn a living and achieve a distinguished position due to his exceptional abilities as a speaker and writer. He actually now develops into this direction. His eloquence procures him ever new opportunities for earning money.[6] I also acted for him in this direction and asked the feuileton editors of the Frankfurter Zeitung whether May could get a chance for a public talk next winter. Maybe you will also have an opportunity to act into this direction in Frankfurt. He will probably soon get the title außerordentlicher Professor [reader/ nontenured lecturer/ extraordinary professor] in Karlsruhe. He will not be able to stay assistant forever and the teaching assignments are revocable."
    May did not receive the announced title until 1.7.1905. Nüsslin had still praised his protégé shortly before, on 26 May, as follows: "As a highly talented teacher, Dr. May fulfilled his lecturing tasks with great zeal and success. He also distinguished himself as a writer, lately in historic-biographic research, and especially as a brilliant speaker, also outside of the university."
    The principal and senate of the university also recommended the awarding commenting that the lectures, which May had held so far, had proven popular with the audience. The difficulties that had to be overcome for awarding May the title of an extraordinary professorare documented in a letter of Nüsslin to Haeckel written on 31 December:
"May has now become a titular professor (extraordinary/ non tenured), but it took effort, because our old miniter of culture, Nokk, a liberal admirer of Goethe, has since died, and the new one initially did not want to mention the issue to the Gand Duke. DEtailed information about the Cimina of May did, however, change his mind and he told me that the Gran Duke was willing to award the title as soon as he heard of the case. The minister also mentioned that May would have faced no more than six weeks of inprisonment for such writings in Baden, instead of 1 year and 1/4 in Sachsen."
---------
[p. 487]
And again on 18 Jan 1906:
"The Senate met yesterday and we discussed the question whether May could be suggested as a replacement for a librarian who had gone, your current colleague Haussner.[7] The majority was decidedly in favor of this and there is no obstacle from the side of the university. However, the responsible referent [head of division] at the ministry thinks that he cannot be made a civil servant because of the past incidents. I was successful in pushing his nomination as a professor ahead vis-á-vis the new minister of cultural affairs, v. Dusch.[8] On that occasion, I also emphasized that Grand Duke Karl Alexander[9] pardoned May upon your petition. Our GRand Duke was immediately willing, as the minister told me later, and showed a sort of warm interest. Maybe I will again visit the minister and I would like to be able to tell him that you were delighted about the liberality of Baden. Though the minister of culture may shudder at your name, such an appreciation from your side will not fail to have the desired effect."
May undertook an expedition in winter 1907/08 (1.11.1907-1.4.1908 from Hamburg) to the Canary islands, and his sister accompanied him as illustrator and photographer. He received a grant of 200 Marks by the Kettner foundation and an additional 500 Marks from the ministry.
    Thereafter, he gave a row of public talks outside of Karlsruhe:
- 7.8.1908 at the International Congress of Historians in Berlin on "Lamarck and Darwin,"
- 23.1.1909 on inheritance in Krupp's Educational Society in Essen,[10]
- 5.2.1909 the ceremonial address for Darwin's 100th birthday in the Society for the History of Natural Sciences in Berlin,
- 8.2.1909 in the Monist Association in Kiel,[11]
- 25.1.1911 on "Goethe as Naturalist" in the Mercantile Society of Sonneberg,
- 16.2.1914 on the 80th birthday of Haeckel in the New Theater of Frankfurt (reviewed in the Frankfurter Zeitung and the Frankfurter Nachrichten of 17.2.1914).
    He curated an exhibition in the assembly hall of the polytechnic university from 28 March to 19 April 1909 on the occasion of Darwin's 100th birthday (12.2.1909). His sister had produced the drawings for it. He stayed in contact with Haeckel through letters until the latter's death (9.8.1919), and he visited Haeckel in Baden Baden on 19.5.1909, when Haeckel stayed there for recreation from 11 May to 5 June.
    Considering the shortage of teachers at intermediate schools, May appealed to be taken into account as a relief staff in natural history subjects on 22.7.1915. However, his application got rejected.
    May was a convinced pacifist and antimilitarist and he explained his mindset in a letter of 54 pages written from 7 to 11 July 1916 to his brother, an officer of contrary convictions. His health was in poor condition at the time so that he was forced to lay in bed most of the day. He concludes his writing as follows:

---------
[p. 488]
"We do not only think differently, but we also feel differently. You feel nationally, I do internationally. I am a born cosmopolitan. I already felt uncomfortable at school, already, when the doctor spoke of the hereditary enemy, when Kröner's words were declaimed: "You shall plunge the steel in the enemy's heart." Today I can still not rid myself of this discomfiture, when the flags fly on the occasion of a victory or even the bells of the Christian churches toll... An unbridgeable gap divides us in matters of worldview. But as humans we can extend our hands brotherly across this chasm."
    Since 1920, he lead the zoological institute as Privatdozent (private lecturer/ unsalaried lecturer/ associate professor), which had lost in importance through the move of the department of forest science of the university to Freiburg. In matters of love May also remained faithful to his socialist convictions, consistent, and without any professional pride. Hence Nüsslin wrote to Haeckel on 26.7.1903:
"He started an earnest love relationship with an indeed decent needlewoman and did not think it necessary to keep this relation a secret. This, of course, left no good impression among the wives of the professors. Additionally, it became apparent that several young girls of very good families with considerable dowries had fallen in love with the lecturer with the interesting head and the holy fire. But May had already given himself away. It's a pity that he is such an oddball, whom one can help so little." 
An again on 31.12.1905:
"What will further become of May is hard to tell, because he wants to marry a simple girl (needlewoman in job). If this was not the case, I would not worry about his future, as there is quite a number of young ladies in best positions that have fallen in love with his beautiful head and mind. Alas, he has so many inexpedient instincts and habits."
His love pertained to Christine (Christel) Wilhelmine Marie Schneider, born in Karlsruhe on 6.5.1872, whom he married only on 26.9.1918. He explained his reasons for the late marriage in a letter to Haeckel on 14.2.1919 as follows:
"Maybe you'd be interested to learn that I married on 26 September last year after a mere 19 years of engagement. Hitherto, the circumstances and social prejudices did not allow a marriage, because my wife is a garment-worker. I could only marry her, if she did not give up her occupation, because my circumstances did not allow me to feed a woman. We now used the war-situation to take the long planned move and the upheavals following the war were in favour of our marriage. Nobody now takes umbrage in the fact that my wife has to earn her living as a needlewoman."
The connection remained childless. Mrs May was committed to the Pflege- und Heilanstalt Ilmenau on 11.10.1926 because of insanity. Thereafter, May's nice Karola ran the household for him. But he died in his flat in Hirschstr. 105 a few weeks later, on 1 December, from Angina pectoris.[12] His wife got delivered from her suffering and existence in an asylum only almost 8 years later. She died from a brain bleeding caused by arteriosclerosis of the blood vessels in the brain on 15.7.1934. May, who was also busy in family research[13] left a library of 8000 volumes including a special collection of works on Robinson and other Robinsonades. Furthermore, a collection of biographical works on naturalists as well as pictures and sculptures of apes. According to the the nice's testimony almost the whole of this legacy has been burnt by the janitor!

    The married couple had been living in very poor conditions as May also had to support his mother for many years with his meager income. Even the costs fro May's funeral had to be payed from the coffers of the senate. His widow, completely penniless, was dependent on public welfare.

Notes 

[1] May had two siblings, a brother Arthur, born on 14.9.1869 in Wetzlar, deceased as retired major on 14.6.1939 in Göttingen and a sister Klara born on 19.1.1871 in Wetzlar, deceased on 19.4.1932 in Kampen/Sylt.

[2] For example, a party member from Chemnitz wrote to him: "When someone fought for a higher cause with such a great zeal as you did, he cannot suddenly change his mind. Whatever they may have promised you, nobody can give you back your political credibility nor replace it. I can imagine what influence you succumbed to. But neither you nor the people who turned you into what you are now will have any delight in you." And Heilmann (1912) even wrote: "May later served the clerics; where he perished is unknown."

[3] Willy Georg Kükenthal (1861-1922), director of the Zoological Institute and Museum in Breslau.

[4] Wilhelm Nokk (1832-1903), Baden state minister.

[5] For example, May wrote to Haeckel on 15.2.1903: "I am extremely busy mainly through many talks in various societies. Currently I give a series of lectures on Darwin's life and theory in the local education association. When I gave a talk in Pfortsheim the other day, I also presented some leaves from your Art Forms of Nature and the local jewelers were delighted to find pattern in them for excellent models, which they are often lacking.

[6] He also offered to give talks, for example, in the journal "Der Monismus" (3, 434, Berlin 1908):

"Mr. Professor Dr. W. May, Professor for zoology at the polytechnic university in Karlsruhe i. B., is willing to give talks in our local associations during the months January to March 1909: 1. On Heredity. 2. My Voyage to the Canary Islands in Winter 1907/08. 3. Charles Darwin's Life and Work. The latter is particularly suitable for Darwin centenary celebrations. Remuneration for Karlsruhe 50 Mark, abroad 100 Mark plus travel costs.

[7] Karl Hermann HAUSSNER (1863-1948), Prof. for Mathematics at the TH since 1904.

[8] Alexander Freiherr von Dusch (1851-1923), Baden State minister.

[9] Incomprehensible error of Nüsslin, a Grand Duke Karl Alexander never existed, back then Grand Duke Friedrich I. (1826-1907) ruled since 1856.

[10] The announcement of the talk in the association's journal „Nach der Schicht" [After the Shift] says: „The visitors will be administered a printed summary of the lecture at the entrance." This is the title number 38 in the list of Walther May's works.

[11] On 2. February May announced a lecture he would give on 10th February in the Narural Science Association of Kassel on the occasion of the 100th birthday of Darwin. Since the proceedings of this association do not contain a reference to it, the lecture seems to have been cancelled for unknown reasons.

[12] A condition of the heart became noticable early on in his life. On 16.2.1904 he already wrote to his mother: "My heart is still the old issue, I can hardly resolve to visit a physician because I would probably not heed his advice anyway." And two days before his death to his brother: "It is really as if all evil spirits had conspired against me, that my condition, which used to be tolerable, suddenly worsened so much: the pains are simply terrible, and who never had them cannot imagine how atrocious it is."

[13] On 6.12.1925 he wrote to his brother: "Concerning family research, I have set up a genealogy of a great grandfather of Christel that is almost 3 meters wide and contains 81 persons excepting the in-law spouses. However, a whole female lineage is still missing, about which Christel knows nothing concrete. Otherwise the genealogy would be much wider still."
