Louis Leprince-Ringuet, born Mars 27, 1901 in Alès and died December 23, 2000 in Paris, is a French physicist, telecommunications engineer, science historian and essayist. Louis Marie Edmond Leprince-Ringuet, son of Félix Leprince-Ringuet, director of the School of Mines, and Marie Stourm, grandson of René Stourm, of the Institute, and great-grandson of the sculptor Victor Paillard, was a student at the École Polytechnique (X1920N, graduated 28th in 1922 out of 205 students). A good part of his family also came from Polytechnique: Leprince-Ringuet, Félix Adrien Louis (X 1892; father; 1873-1958), Leprince-Ringuet, Henri René André (X 1899; uncle; 1878-1961), Leprince- Ringuet, Jean Marie Gabriel (X 1923; brother; 1904-1992).)

He married Denise Paul-Dubois, granddaughter of Paul Dubois and Hippolyte Taine. Widowed after seven months of marriage, he remarried Jeanne Motte in 1929. They had seven children together, including Dominique Leprince-Ringuet who was killed in 1966 while climbing Mount Huascaran in Peru1.
Studies

He continued his studies at Supélec from 1920 to 1923, then at Télécom Paris (class of 1925, year of exit)2, before becoming an engineer in the Submarine Cable Service.
Physicist, researcher and teacher

From 1929, he worked with Maurice de Broglie at the X-ray physics laboratory. It was thanks to the latter - whom he would later describe as his "spiritual father" - that he began to work on what would become his specialty, nuclear physics. He created his own nuclear physics laboratory. We owe him the discovery of the “U meson” [ref. necessary].

He taught physics at the École Polytechnique from 1936 to 1969 (succeeding Charles Fa
