I sometimes cite Tesla as a superbrilliant guy with little business sense. As Craig pointed out, he could have been Gigawealthy but he somehow managed to avoid any sort of monetary accumulation.
I like to think that he was still able to do everything that he desired in life and that he knew all along that he couldn`t take it with him so he never bothered.
If you want a fun book to read about Tesla, try this one:
TESLA: Master of Lightning
By Margaret Cheney & Robert Uth
It`s an easy read, full of some awesome pictures, and you will fall in love with everything Tesla. Very sad that this man does not get the recognition in our society that he deserves.
Think of it this way, it`s possible that none of us would be here at SuN if not for him! An amazing man!
