Probably not polio. More likely his mom took Thalidomide during pregnancy. That happened to one of my classmates in high school. His left forearm and hand never developed past the fetal stage. His right arm was fine. Aside from the left arm, he was a perfectly bright and capable person.
He would have been born during WW II. I think that was pre-thalidomide. I'm pretty sure he said polio did it.
But it's been a few miles since then and now.
Thalidomide was never FDA approved in the US to treat morning sickness. In the late '80's or early '90's it was approved to treat cancer but it has a black box pregnancy warning and only certain doctors can prescribe it.
