TITLE: Early examples of mathematicians publishing (from home) in a foreign language?
QUESTION [11 upvotes]: Today this is common, but how exactly did it start? I am looking for examples in various languages, and suggest:

Exclude Latin (as more “ancient” or “international” than “foreign”)
Exclude French after, say, Huygens (as well-known: Leibniz, Euler, Jacobi, Dirichlet, etc.)
Exclude anything resulting from a visit or permanent move to the foreign country (thus Cauchy or Riemann in Italian, World War refugees in English, etc.)
Exclude translations not originated by the author.
Do not otherwise exclude (early) English and German!

Bend these rules if necessary. Mathematical physics or celestial mechanics qualify. This ties in with various questions at hsm, but I am hoping for a wider pool of knowledge here. So far I am only aware of isolated(?) examples by Abel, Plücker, Lie, Lorentz, without clear lineage to the present.

REPLY [7 votes]: The obvious examples would include pretty much anyone who was not born speaking any of the "Congress" languages. They (or should I say "we", being Polish) would  publish their mathematics in a more widely spoken/read language in order to increase the chance of its being read and understood.  Let me however give some less obvious answers involving two Polish students of Sophus Lie (still having to do with dissemination of the ideas, perhaps tailoring to the intended audience).  Kazimierz Zorawski  (1866-1953; PhD 1891) published over 70 works in his lifetime, roughly half of them in German and half in Polish (understandable). However, there are also 3 works in Czech (1914-1915). He was a member of the Czech Academy (since 1910), but otherwise had no Czech connection.  Another student of Lie, Lucjan Emil Boettcher (1872-1937; PhD 1898), published mainly in Polish (with some early and late exceptions in German and French), but his most cited paper is "Glavnyshiye zakony skhodimosti iteratsiy i ikh prilozheniya k' analizu" ("Main laws of convergence of iterations and their applications to analysis"). He published it in 1903-1904 (in parts) in Russian, in "Bulletin de la Societe Physico-Mathematique de Kasan".

REPLY [3 votes]: A surprisingly recent example:
Don Zagier:
Een ongelijkheid tegengesteld aan die van Cauchy
Proc. Koninkl. Ned. Akad. v. Wetensch. (Indag. Math.) 80 (1977) 349-351

There are also several papers in French in Zagier's
list.
