Rita Levi-Montalcini

Rita Levi-Montalcini (22 April 1909 – 30 December 2012) was an Italian neurobiologist and physician who discovered nerve growth factor (NGF), a protein that regulates the growth, maintenance, proliferation, and survival of certain target neurons. For this breakthrough, she shared the 1986 Nobel Prize in Physiology or Medicine with American biochemist Stanley Cohen, who independently identified epidermal growth factor (EGF).

Born in Turin to a Sephardic Jewish family, Levi-Montalcini graduated in medicine from the University of Turin in 1936 and initially worked as Gustav Levi's assistant in histology and neurology. The 1938 Italian racial laws under Fascism, which prohibited Jews from academic and professional roles, forced her to abandon her university position; she fled briefly to Belgium in 1939 but returned to Italy after the German invasion. During World War II, she conducted pioneering research on neural development in a clandestine laboratory improvised in her bedroom, using chick embryos to observe nerve cell responses to limb ablation and tumor implants, which led to her initial identification of a nerve growth-promoting agent.

Rita Levi-Montalcini was born on April 22, 1909, in Turin, Italy, into a Sephardic Jewish family of middle-class means with roots tracing back centuries in the region. She was the youngest of four children, including an older brother, Gino, who became an architect, and an older sister, Anna; Levi-Montalcini shared an identical twin sister, Paola, who pursued a career as an artist.

Despite these constraints, Levi-Montalcini's upbringing emphasized self-reliance and freethinking, influenced by her father's engineering mindset and her mother's artistic sensibility, which her twin sister Paola embodied professionally. The family's Jewish heritage, while culturally observant, did not impose strict religious orthodoxy, allowing flexibility in personal development amid Italy's pre-fascist secular society. This background instilled resilience, as Levi-Montalcini later reflected on overcoming familial reservations to pursue medicine, viewing imperfection as a driver of human achievement.

Rita Levi-Montalcini was born on April 22, 1909, in Turin, Italy, as the youngest of four children in a secular Sephardic Jewish family; her father, Adamo Levi, was an electrical engineer and mathematician who emphasized intellectual rigor at home, while her mother, Adele Montalcini, was a painter whose artistic influence permeated the household. She shared an especially close twin bond with her sister Paola Levi-Montalcini, born minutes after her and later renowned as a painter who created notable portraits of Rita; the twins maintained lifelong companionship, cohabiting in Rome from 1977 onward after Rita's return from the United States, with Paola providing emotional support amid Rita's scientific pursuits. Their older brother, Gino Levi-Montalcini, an architect, and sister Anna also contributed to a family environment marked by creative and professional achievements, though Gino's death in 1971 and Paola's in 2000 preceded Rita's own longevity.
