I've had to ask Grok. I didn't know Jonas Salk was Jewish.

One significant invention by Jews for the betterment of the world is the polio vaccine. Developed by Jonas Salk, who was born into a Jewish family, this vaccine has played a crucial role in nearly eradicating polio, a devastating disease that once caused widespread paralysis and death.

Jonas Salk famously declined to patent his polio vaccine. In a television interview with Edward R. Murrow in 1955, when asked who owned the patent, Salk responded, "Well, the people, I would say. There is no patent. Could you patent the sun?" This decision allowed the vaccine to be widely distributed without the constraints of patent restrictions, significantly aiding in the global fight against polio.
