He was a good one
I would often confuse him with Pohl Anderson, who was a contemporary and sometime collaborator.
Both were prolific short story writers. They churned out at least 1-2 every month.
The only Fredrick Pohl novel I read was "The Space Merchants". It was a brilliant work that I would need to reread to fully describe it. It involved recruiting volunteers for a Venus colony. I remember liking it a lot but much of the details are lost in my synapses.
