<human>: I'd like to know the names of the most influential people in the history of medicine.
<bot>: The most influential person in the history of medicine is probably Alexander Fleming, who discovered penicillin in 1928. He was awarded the Nobel Prize in 1945 for his discovery. Other important medical figures include Louis Pasteur, who developed vaccines and treatments for diseases such as rabies, cholera, and anthrax; Joseph Lister, who invented antiseptic surgery; and Jonas Salk, who developed the first successful vaccine against polio.
