Had not heard this until I saw LA's obit here.
Never met the man, although did hear him speak once.
LA's picture is from the cover of The Way the Future Was: A Memoir by Pohl.
If you are at all interested in early Science Fiction writers of the great flowering of the genre, it's one of the two most interesting accounts, along with Damon Knight's The Futurians.
Pohl was used by Isaac Asimov as the counter example to his own comment that levels of education often reflected a person's intelligence.  The two originally met when they were in high school. Asimov had a PHd in chemistry while Pohl did not go past 12th grade. Asimov considered Pohl as perhaps the most intelligent person he ever met.
Pohl was as important as an editor and agent as he was as a writer,  although few received more writing awards.
In all three roles he was important to the development of at least two generations of authors.
