Q. Who won 2 Nobel Prizes

Marie Curie is the most famous person to have won two Nobel Prizes in different scientific fields—she received the Nobel Prize in Physics in 1903 (shared with her husband Pierre Curie and Henri Becquerel) for their work on radioactivity, and the Nobel Prize in Chemistry in 1911 for her discovery of radium and polonium. Her achievement is particularly remarkable not only because she won in two different sciences but also because she was the first woman to win a Nobel Prize and remains the only woman to have won Nobel Prizes in multiple scientific disciplines. Her work fundamentally changed our understanding of atomic physics and chemistry, and her legacy continues to inspire scientists worldwide, particularly women in STEM fields.

Linus Pauling is another individual who won two Nobel Prizes, though in his case, both were in different categories—the Nobel Prize in Chemistry in 1954 for his research on chemical bonds, and the Nobel Peace Prize in 1962 for his activism against nuclear weapons testing. John Bardeen, the American physicist, won the Nobel Prize in Physics twice—in 1956 for the invention of the transistor and in 1972 for the theory of superconductivity—making him the only person to win the Nobel Prize in the same category twice. Frederick Sanger also won the Nobel Prize in Chemistry twice, in 1958 and 1980, for his work on the structure of proteins and DNA sequencing. The International Committee of the Red Cross has won the Nobel Peace Prize three times (1917, 1944, 1963), though this is an organization rather than an individual. These multiple Nobel laureates represent the pinnacle of sustained excellence and groundbreaking contributions to science, peace, and humanity.
