Rita Levi-Montalcini

Rita Levi-Montalcini (April 22, 1909 – June 30, 2012) was an Italian neurobiologist who won the Nobel Prize in Physiology or Medicine in 1986 for her discovery of nerve growth factor (NGF), a protein crucial for the development and function of nerve cells. Born in Turin, Italy, to a Jewish family, she pursued science despite societal barriers against women in academia and faced additional obstacles under Fascism and World War II. During the Nazi occupation of Italy, she worked in hiding, conducting experiments with chicken embryos using improvised laboratory equipment. Her groundbreaking research, conducted in collaboration with biochemist Stanley Cohen, revealed how growth factors regulate cell development and differentiation—work that fundamentally transformed our understanding of biology. Beyond her scientific achievements, Levi-Montalcini was a passionate advocate for peace, women's rights, and scientific education. She remained active in research and public life well into her 100s, continuing to write and speak about science and ethics. Her legacy extends beyond her Nobel Prize-winning discovery to her role as an inspiration for women in science and her lifelong commitment to using knowledge for humanitarian purposes.
