I'd say go either to an article published, I think, in IEEE several years ago, a great article with many details about him developing his CW, including the generator, or go to Wikipedia, whose article on him is not bad either.

But he was a phenomenal guy.
And even though he reaped little from his inventions (RCA settled with him for enough money for him to comfortably live in the estate he bought) I think one of the sweetest revenge moments on his rivals like Marconi, who laughed at him, was when Marconi had to buy the license from him for CW, therby admitting defeat.
