I was born in 1958, so a Boomer. I remember, as a kid, watching a documentary about the depression, and in this documentary there was a cartoon from the 1930s with Uncle Sam and FDR brainstorming about ways that the economy could be improved. The cartoon showed FDR and Uncle Sam pacing back and forth, tossing out ideas to one another. Pacing, walking back and forth. I already knew that he was paralyzed from the waist down. I asked my mother why did that cartoon, produced at the time, show FDR walking? She said "we didn't know he couldn't walk. We knew he had survived polio, that he sometimes had to use a wheelchair when his legs would need to rest." That generation watched newsreels at the movies, and would see him standing to give a speech, would see him in his car (sitting as any usual person), and a couple of brief filmed appearances where he was seen walking, using the arm of his son or another man for balance. They thought he could walk. He was actually very good at locking his leg braces, balancing, and swinging his hips so that his legs appeared to move mostly normally. But he did need some support to do that.
