Rita Levi-Montalcini: The Bedroom Laboratory
Barred from academic work by Mussolini's 1938 racial laws, she built a laboratory in her own bedroom in Turin and dissected chicken embryos with sharpened sewing needles under a microscope while the war went on outside. The work she did there — illegal, unfunded, conducted by a woman the state had declared unfit to hold a job — became the foundation of the discovery that won her the Nobel Prize in Physiology or Medicine in 1986. She lived to 103, and served in the Italian Senate until the day she died.
Turin, and a Father's Objection
Rita Levi was born in Turin on 22 April 1909 to Adamo Levi, an electrical engineer and mathematician, and Adele Montalcini, a painter. The family was Italian Jewish, with roots the article traces to the Roman Empire and Sephardic heritage from Asti and Casale Monferrato. She had a twin sister, Paola, who became an artist, a brother, Gino, who became an architect, and a sister, Anna. As a teenager she admired the Swedish writer Selma Lagerlöf and thought of becoming a writer herself; watching a close family friend die of stomach cancer changed her mind and sent her towards medicine. Her father initially opposed higher education for his daughters, believing it incompatible with the life of a wife and mother, and eventually relented.
The Manifesto of Race
She entered the University of Turin medical school and graduated summa cum laude with an M.D. in 1936, having studied under the neurohistologist Giuseppe Levi, who directed her attention to the developing nervous system — the subject she never left. She stayed on as his research assistant until 1938, when Mussolini's Manifesto of Race barred Jews from academic and professional careers. From 1939 to 1943 she ran her clandestine bedroom laboratory, studying nerve fibre growth in chick embryos. After the German invasion in 1943 the family fled to Florence and survived the Holocaust under assumed identities, sheltered by non-Jewish friends. When Florence was liberated in August 1944 she volunteered her medical training with the Allied health services, working among refugees.

Take the IQ test →Thirty Years in St. Louis
In 1946 she accepted what was meant to be a one-semester fellowship with Viktor Hamburger at Washington University School of Medicine in St. Louis. She stayed thirty years. Working there in 1952, she transplanted fragments of mouse tumour tissue into chick embryos and watched nerve fibres proliferate in a dense halo around the tumour cells — growth so abundant she described it as looking "like rivulets of water flowing steadily over a bed of stones." The tumour, she reasoned, was releasing a substance that made nerves grow. With Hertha Meyer she published the first definitive evidence of the protein in *Cancer Research* in 1954, in a paper on the effects of mouse sarcomas 180 and 37 on the spinal and sympathetic ganglia of the chick embryo. She was promoted to full professor in 1958.
Nerve Growth Factor
Nerve growth factor turned out to be the protein responsible for the growth and maintenance of neurons in the sympathetic and sensory nervous systems — the first of the growth factors to be identified, and the opening of an entire field. It demonstrated linkages between the nervous, immune and endocrine systems and reframed how researchers approach neurodegenerative disease. The biochemist Stanley Cohen, who purified the factor, shared the 1986 Nobel Prize with her, along with the Albert Lasker Award for Basic Medical Research that year. She received the National Medal of Science in 1987. In 1962 she opened a second laboratory in Rome and thereafter divided her time between the two cities, directing the Research Center of Neurobiology of the Italian National Research Council from 1961 to 1969, the Laboratory of Cellular Biology from 1969 to 1978, and the Institute of Cell Biology from 1977 to 1979. In 1993 she identified palmitoylethanolamide as an important modulator of mast cells, and she was among the first scientists in the 1990s to press the case for mast cells' role in human pathology.
The Senator
President Carlo Azeglio Ciampi appointed her senator for life in 2001, a post she held until her death in Rome on 30 December 2012. It was not a ceremonial retirement. Right-wing senators attacked her votes supporting Romano Prodi's government between 2006 and 2008, and the far-right politician Francesco Storace mocked her age. In 2003 she sued the comedian Beppe Grillo for libel after he called her "an old whore" during a performance. She never married, and was unapologetic about it: "I never had any hesitation or regrets in this sense... My life has been enriched by excellent human relations, work and interests. I have never felt lonely." She founded the European Brain Research Institute in 2002 and the Rita Levi-Montalcini Foundation, which supports education and research for young women in Africa and Italy.
Why Rita Is Called a Genius
The cognitive quality is interpretive nerve applied to a visual anomaly. The halo of nerve fibres around the transplanted tumour was, in strict terms, a curiosity; what distinguished Levi-Montalcini was refusing to treat it as an artefact and instead reasoning to a diffusible chemical signal — an entity nobody had shown to exist. Discovering that developing tissue is instructed by soluble factors rather than merely by contact and position reorganised developmental biology, and the Nobel committee's recognition in 1986 reflects that the finding opened a field rather than closing a question. The second, less discussed quality is sheer persistence under conditions designed to stop her: a state-enforced ban, a bedroom bench, homemade instruments, and later three decades of unglamorous work in a foreign country before the prize arrived.
The honest counter-case is that the discovery was collaborative and incomplete without others. Viktor Hamburger's laboratory supplied the embryological framework and the question; Stanley Cohen did the biochemistry that isolated and characterised the protein, and shared the prize for good reason. Her later record is genuinely mixed: the long association with the pharmaceutical firm Fidia and her support for Cronassial, a bovine-brain ganglioside preparation later linked in some patients to Guillain-Barré syndrome and banned in Germany in 1983 and Italy in 1993, drew public criticism after investigators found Fidia had paid the Italian Ministry of Health for rapid approval and promotion in untested applications. Her governance of the European Brain Research Institute was criticised in 2010 as autocratic. Genius in observation did not immunise her against institutional misjudgement.
Legacy
She was the tenth woman elected to the US National Academy of Sciences, in 1968, a foreign member of the Royal Society from 1995, and in 2009 the first Nobel laureate to reach a hundred. An orchid, *Ophrys × montalciniae*, carries her name. So does a generation of Italian and African women scientists whose education her foundation paid for.
