Jean Alexandre Barré

[2] He studied medicine in Nantes, afterwards serving his internship in Paris, where he was influenced by Joseph Babinski (1857–1932).

In 1912 he obtained his medical doctorate with a thesis on osteoarthropathy associated with tabes dorsalis.

During World War I, he worked in a neurological unit of the 6th army, directed by Georges Guillain (1876-1961), with whom he began a longtime collaboration.

With Guillain, he was co-author of Travaux neurologiques de guerre (1920), a book that was published in three editions.

[4] His doctoral thesis, Les osteo-arthropathies du tabès, was a continuation of Jean Charcot's research of the disorder.
