In Chapter I.9 of Chandler-Magnus "The History of Combinatorial Group Theory", a number of important mathematicians in the early history of the development of group theory and sources for their obituaries are given. For example, we certainly find an entry Dehn, Max, 1878-1951. For other names, less information is known, such as Pick, G., 1859-1943(?). This latter question mark reflects the fact that Georg Pick died in the Theresienstadt concentration camp in 1942, and finding this information might have been difficult at the time of the writing of the book (1982).

All names in this list have a source for where their obituary may be found, and at least one of a birthyear or death year is present -- except for one name. This name is listed simply as H. Vogt: ?-?., with no further information. Curiosity piqued, this gives my question:

Who was H. Vogt? What were his mathematical contributions?

Here's the clues I've got this far. The most relevant piece of information is the following paper:

  • Vogt, H., Sur les invariants fondamentaux des équations différentielles linéaires du second ordre. , Ann. Sci. École Norm. Sup. (3) 6 (1889), 3–72. (Thèse, Paris),

This paper is the only paper cited by Chandler and Magnus for Vogt, and is hence the only publication I am certain is by the desired H. Vogt. It also appears to have been his Ph.D. thesis. No result can be found on Mathematics Genealogy matching this.

There are a number of matches on MathSciNet for publications by an H. Vogt; the earliest is from 1879, by a Heinrich Vogt, and this could in principle be the same H. Vogt as above. The latest that could conceivably be by our H. Vogt is from 1923 -- this is again on differential equations, so seems very likely to be by the same author!

This would give a (very!) rough idea of (1860-1930) as the lifespan of our dear H. Vogt -- perhaps this helps the search.

One idea is that H. Vogt could possibly be related to (father of?) Wolfgang Vogt, a young German mathematician whose last paper was in 1914, and who may well have perished, as did so many other young German academics at the time, in World War 1, such as Werner Boy, of Boy's surface fame, and Hugo Gieseking. The topic of his 1906 Ph.D. thesis seems -- at least on a surface level -- somewhat related to what H. Vogt did, especially if some of the other publications on MathSciNet were by the same H. Vogt.

Note: there is a 1932 paper by someone called H. Vogt, namely Vogt, H., Max Wolf., Astronomische Nachrichten 247, 313-316 (1932). ZBL59.0039.09. However, this seems to be by the nazi astronomer Heinrich Vogt (1880-1968), who seems unrelated (and likely did not write an article about differential equations at the age of 1).

  • $\begingroup$ @F.C. Yes, but as far as I could tell this was not much more enlightening than MathSciNet (in that it provided many different H. Vogt's and little more information about any given one of them). $\endgroup$ Mar 17 at 16:22

    $\begingroup$ It seems that the article (thesis) you cite is attributed by ZBMath to Vogt, Henri Gustave $\endgroup$

  • $\begingroup$ @F.C. I can't believe I missed this! And that name leads to... a Portuguese Wikipedia article, giving his lifespan as 1864--1927 (it seems my guess for his lifespan was eerily close!) $\endgroup$ Mar 17 at 16:26

A short necrology of Henri Gustave Vogt can be found here:

His 1924 discourse on Henri Bazin here:

Some comments on his entry in the Académie de Stanislas in 1921 are here:

He has received the Légion d'Honneur:

http://www2.culture.gouv.fr/public/mistral/leonore_fr?ACTION=RETROUVER&FIELD_1=NOM&VALUE_1=VOGT&NUMBER=17&GRP=0&REQ=%28%28VOGT%29%20%3aNOM%20%29&USRNAME=nobody&USRPWD=4%24%2534P&SPEC=9&SYN=1&IMLY=&MAX1=1&MAX2=1&MAX3=100&DOM=All

This says that he is born the 24th of January 1864 in Sermaize (Marne).

His "acte de naissance" says that his correct name is "Henry Gustave". He is the son of Jacques Georges Vogt and Charlotte Gabrielle Cavelier.

The last document in the Légion d'Honneur file contains a short biography!

Here comes a photography as a young student in 1881:

Henri Vogt as a student of the ENS in 1881

New information:

I have got a scan of the front and back pages of his PhD thesis, where we learn that

  1. The "Commission d'Examen" was composed of Hermite (président) and Appell and Poincaré (examinateurs)

  2. The thesis is dedicated to Appell: "À Monsieur Appell, Hommage de respectueuse reconnaissance".

I would be tempted to deduce that Appell was his advisor.

According to Zentralblatt (which is freely accessible on Internet, since Jan 1, 2021, btw) Henri Gustave Vogt was a mathematician, apparently French, since he wrote in French, published in French journals, and his first and second names use French spelling, though his last name hints German origin.

In Zentralblatt, we find 28 publications, including 14 books, beginning in 1889.

His by far most famous paper is the one you mention. See also

William Goldman, An exposition of results of Fricke and Vogt, arXiv:math/0402103.

for a modern exposition of this paper.

    $\begingroup$ Just a minor comment: I'm not sure I agree that the name Gustave '[reveals] a German origin'. Although it's probably rare nowadays, I think it used to be a relatively common French name. Gustave Flaubert comes to mind, for example. $\endgroup$

    $\begingroup$ Indeed, Gustave is a French name. The German equivalent is Gustav (or, less commonly, Gustaf). $\endgroup$ Mar 17 at 17:40

    $\begingroup$ "apparently French, since he wrote in French" many people wrote in French during the 19th century, and even into the first half of the 20th century. $\endgroup$

    $\begingroup$ @LeoMoos even more Henry or Henri; the German equivalent was Heinrich; nowadays its not uncommon that Germans have a "reimported" name. $\endgroup$ Mar 18 at 4:30

    $\begingroup$ Perhaps people in the future will erroneously think that many mathematicians are English because most people write in English. $\endgroup$ Mar 18 at 18:12
