I'm coming towards the close of a good (yet dated) book: Men of Mathematics, by E.T. Bell. For those of you who haven't read it, the book gives a detailed accounts of the lives up the many recent greatest mathematicians and also touches upon the work they did. Is there a book that would be akin to Bell's but for physics instead? A "Men of Physics" per se that discusses the lives of men like Einstein, Bohr, Thompson, etc.
