H. Beam Piper, a science fiction author.
He was a somewhat popular author in his day, but not popular enough to make a living at writing (he killed himself because he was broke and couldn't sell any more of his writing, apparently).
His politics would probably rub a lot of people the wrong way nowadays (and back then, even - he'd be at home at a Tea Party event), but pretty much define his works. Every time I read his most famous novel,
Space Viking, I can't help but thing it's very very relevant to today.

(His work is out of copyright in the US, but I guess not Canada? Go figure. Gutenberg has it, as do a lot of places)
