An Italian-American neurologist, Rita Levi-Montalcini discovered nerve growth factor (NGF), revolutionizing neurobiology. She won the Nobel Prize in Medicine in 1986, and continued her research despite fascist racial laws that forced her to work in secret. She remained active in science past the age of 100.

- Discovered nerve growth factor (NGF) in the 1950s during her work at Washington University in St. Louis.
- Awarded the Nobel Prize in Physiology or Medicine in 1986, shared with Stanley Cohen, for the discovery of NGF.

Works & Achievements
Rita Levi-Montalcini's landmark scientific discovery: the identification of a protein that stimulates the growth and ensures the survival of neurons. This discovery revolutionized neurobiology and paved the way for understanding neurodegenerative diseases such as Alzheimer's and Parkinson's.
A foundational scientific publication in the Proceedings of the National Academy of Sciences, presenting nerve growth factor to the scientific world for the first time. This paper went on to become one of the most cited references in cell biology.
An autobiography published the year after she received the Nobel Prize, in which Rita Levi-Montalcini traces her life from childhood in Turin to her scientific recognition. Translated into many languages, the book is both a testament to science and a personal account of resistance to totalitarianism.
A European brain research institute founded in Rome by Rita Levi-Montalcini to accelerate the understanding and treatment of neurodegenerative diseases. She served as its scientific director well into the later years of her life.
A work of popular science in which Rita Levi-Montalcini pays tribute to the great unsung scientists of history. It reflects her lifelong commitment to bringing scientific culture to the general public.
Anecdotes
When the fascist racial laws of 1938 barred her from practicing medicine as a Jewish woman, Rita Levi-Montalcini set up a clandestine laboratory in her bedroom in Turin. She dissected chicken embryos on her nightstand, refusing to let Nazi ideology extinguish her passion for science.
In 1943, driven out of Turin by the Allied bombings, she fled with her family to Florence under a false identity. There she continued her research in secret, carrying her precious embryos and microscope in a suitcase, risking her life rather than abandon science.
In 1952, during a pivotal experiment in Rio de Janeiro with Hertha Meyer, Rita Levi-Montalcini observed for the first time under the microscope an explosion of nerve fibers growing around a tumor. She described this vision as 'the most beautiful of my entire scientific career' — the very night she realized she had just discovered nerve growth factor.
Appointed Senator for Life in Italy in 2001 at the age of 92, she continued to sit in the Senate and vote on legislation into her final years. In 2006, at 97, she declared that her brain was functioning better than ever, attributing her intellectual longevity to curiosity and a passion for knowledge.
When the Nobel Prize was announced in 1986, Rita Levi-Montalcini was 77 years old. She shared the prize with Stanley Cohen, her American collaborator. In her Stockholm address, she paid tribute to Viktor Hamburger, the researcher who had invited her to Saint Louis, stating that without that encounter, her discovery would never have come to light.
Primary Sources
Nell'autunno del 1938, mentre ascoltavo alla radio il discorso di Mussolini che promulgava le leggi razziali, non provai terrore, ma una fredda determinazione: avrei continuato a fare ricerca, in qualunque modo.
The discovery of NGF in the early 1950s came about as a result of a series of strange and unpredictable events... I looked at the tumor and suddenly the most beautiful sight confronted my eyes: a dense halo of nerve fibers around the tumor.
A nerve growth-stimulating factor has been extracted from mouse sarcoma 180 and 37... The factor stimulates growth and differentiation of sensory and sympathetic ganglia in the chick embryo.
I thank you for giving me this opportunity to work in Saint Louis. The results we are obtaining on nerve fiber growth exceed anything I would have dared hope for.
Key Places
Rita Levi-Montalcini's birthplace, where she studied medicine and set up her first clandestine laboratory in her family bedroom in 1940, defying fascist racial laws.
The city where the Levi-Montalcini family took refuge in 1943 under false identities, fleeing the bombing raids and Nazi persecution. Rita continued her research underground until the Liberation in 1945.
The laboratory of Professor Viktor Hamburger, where Rita Levi-Montalcini settled in 1947. It was here that she and Stanley Cohen conducted the work that would lead to the discovery and isolation of NGF.
In 1952, Rita Levi-Montalcini worked here with biologist Hertha Meyer, a pioneer in tissue culture. It was here that she first observed under the microscope the spectacular proliferation of nerve fibers induced by NGF.
The Roman laboratory she founded and directed from 1962, which became one of the most important neurobiology research centers in Europe. She continued her work on NGF there and trained several generations of researchers.
