In his correspondance with Jimmie Savage and Will Baumol in the early 1950s, Maurice Allais would write in French and the two Americans would reply in English. Also Italian mathematician Bruno de Finetti started his corrspondance with Savage in French in the 1940s, although he switched to English in the mid 1950s. In addition, it appears from remakrs here and there that people such as Samuelson, Baumol and Savage could read German, that Savage’s Latin wasn’t so bad, but that Baumol apologized not being able to read Latin.
Which all begs the question: In general, how well did American economists in the twentieth century read and speak other languages? Could American professors in the 1920s, 1950s and 1980s be expected to read French and/or German? Or was this really an exception?
Dans l’attente de votre réponse, je vous prie d’agréer, mon cher Baumol, mes salutations distinguées.
