Kaluza's paper to Einstein

[Terry Giblin]

Where can I get a copy of the paper Theodor Franz Eduard Kaluza, sent to Albert Einstein.

Any help would be greatly appreciated.

I assume you are refering to Kaluza's 1921 paper "Zum Unitätsproblem der Physik" which Einstein refereed and finally recommended for publication. I'm not aware of an online version of the paper, at least not in english. An english translation of that paper, and letters to Kaluza from Einstein relating to that paper can be found here: "Unified Field Theories of More than 4 Dimensions" (Singapore: World Scientific, 1983), 427-33; 447-57
