Some previous questions on Einstein bring the following question: is a complete (or incomplete) list of Einstein assistants available somewhere?
A quick search on the Internet brings several familiar names, but no list. I know many of them, but I would like to see a complete list, with dates of employment, if possible. Of course, one can look at the list of his co-authors, but not all assistants co-authored papers with him. Some of them were (or later become) famous mathematicians. As I understand, this was a formal payed position: a German professor was eligible to have assistants. This applies to the period when Einstein worked in Berlin. Perhaps he also had an assistant in Princeton, I am not sure.
EDIT. Here are the candidates whom I extracted from the publicaton list until 1938: W. Mayer (8), N. Rosen (4), J. Laub (3), L. Hopf (2), W. Ritz, O. Stern, A. Fokker, B. Hoffmann and P. Bergmann. (Other co-authors in this period are Lorenz, Minkowski, de Sitter and Grossmann, but they were not his assistants). Later publications add V. Bargmann, B. Kaufman, H. Born, A. Lande, S. Penner, B. Podolsky, and few other people who could not be his assistants.
Cornelius Lanczos was an assistant in 1928-29 but never co-authored a paper.
