Jonas Salk, just the dude who created the first efficacious and safe polio vaccine in the 1950s. He didn't patented it, didn't earn a cent from it, 'cause he wanted it to be as accessible as possible.
In this paper he writes: "It would appear from this review that responsibility for the problem of eliminating paralytic poliomyelitis rests with each individual for whom there is a need for vaccine, either for himself or for those for whom he is responsible; this responsibility is shared by those who are in a position to bring this knowledge to him and to help him avail himself of the necessary treatment. Little need be said about this other than to emphasize that the indications provided in this review suggest that there need be little, if any, paralytic poliomyelitis in the United States in 1957 if all who are potentially susceptible are treated with vaccine that is now available."
