Here's a golden anniversary worth celebrating. I was born in 1955, so I don't remember a fear of swimming pools and urban crowds. I don't remember polio as anything but as the disease that crippled FDR, all because of the discovery that was announced by Jonas Salk on April 12, 1955:
"He further endeared himself to the public by refusing to patent the vaccine. He had no desire to profit personally from the discovery, but merely wished to see the vaccine disseminated as widely as possible."Exactly like all those selfless capitalist drug companies today.
