Silberstein was as we all know an interesting thinker, working early and with some elegance in relativity, though he did run into a spot of bother with Einstein in which the good Dr. Silberstein fared not so well. I’ve always rather “liked” Silberstein for his early work on relativity.
“Ludwik Silberstein (1872 – 1948) was a Polish-American physicist who helped make special relativity and general relativity staples of university coursework. His textbook The Theory of Relativity was published by Macmillan in 1914 with a second edition, expanded to include general relativity, in 1924.”–Wikipedia
