The chair of applied mathematics at the University of Nancy became the responsibility of Jules Molk in 1890 following the death of Émile Léonard Mathieu. A French mathematician specialized in elliptic functions, his academic path included studies at Humboldt-Universität zu Berlin and a career as a university teacher that spanned the turn of the twentieth century.
Academic Background and Early Career
Born in Strasbourg in 1857, Molk developed a command of German scientific literature during a residency in Berlin between 1880 and 1884. His doctoral thesis focused on German mathematical breakthroughs, providing a foundation for his later international collaborative efforts. He spent his career in France, ultimately settling at the University of Nancy where he served as a professor of rational mechanics.

Take the IQ test →The Encyclopedic Project
Beginning in 1902, Molk served as editor-in-chief for the French edition of the encyclopedia of pure and applied mathematical sciences. This project, based on Felix Klein's German encyclopedia, served as more than a simple translation, functioning as a deliberate re-reading of the material. The work involved coordinating numerous scholars, including Paul Appell, David Hilbert, Émile Borel, and Maurice Fréchet. Despite difficulties with the release schedule and publishing house operations, the first volumes reached the public in 1908, with final segments appearing in 1916.
Recognition and Legacy
Molk earned professional acclaim for his contributions, including election to the German Academy of Sciences Leopoldina in 1906. He received the Binoux Prize in 1912 and was designated a Knight of the Legion of Honour. His research output included a significant four-volume work on the theory of elliptic functions, co-authored with Jules Tannery. He died in Nancy in 1914 at the age of 57.

Questions readers ask
What was the significance of the encyclopedic project Molk led?
It represented a new form of Franco-German scientific collaboration that acted as an erudite re-reading of German mathematical sciences rather than a direct translation.
Where did Jules Molk teach?
He served as a professor at the University of Nancy, where he held the chair of applied mathematics and taught rational mechanics.
