It's well known that Dick and Heinlein were friends. On Dick's wikipedia article there is an extract from the introduction to the 1980 short story collection The Golden Man in which Dick praises Heinlein for how he helped him during the tough times.
I've searched the internet for more info about their friendship and apart from the alleged present of a typewriter from Heinlein you don't find much.
This is history, as they say, and I'd like to learn more. Anyone can provide more details about the interaction of these two writers?
