Jeanne Ferrier

Jeanne Ferrier (April 6, 1888, Montpellier – May 23, 1979, Paris) was a French physicist. She was a pioneer in the field of radiotherapy.

Biography After earning a dual degree in mathematics and physics from the University of Montpellier, Jeanne Ferrier became a science teacher at a boys' high school in Tarbes.

In 1910, she married her professor, Samuel Lattès, who died in 1918. After becoming a widow for the first time, she moved to Paris and joined Marie Curie's laboratory with the support of a Carnegie grant.

Around 1930, health concerns compelled her to cease working with radioactivity. She then joined the Henri Poincaré Institute as an assistant in probability calculations under Émile Borel's guidance, where she worked until her retirement in 1958.

Family Jeanne Ferrier was first married to Samuel Lattès on August 17, 1910, and became a widow in 1918, with one daughter from this first marriage. In her second marriage, she wed her collaborator, physicist Georges Fournier, on August 31, 1929, with whom she had two children.

Notable works Jeanne Lattès conducted research in the field of radioactivity, including studies on tissue necrosis caused by radium radiation and the detection of radioactive elements in cells. Some of her notable works include: "Sur les conditions physiques qui accompagnent le phénomène de nécrose produit par les rayons du radium" (On the Physical Conditions Accompanying the Phenomenon of Necrosis Produced by Radium Rays) – Comptes rendus de l'Académie des sciences, 176 (1923), 867–869.
