Marguerite Catherine Perey (19 October 1909 – 13 May 1975) was a French physicist and a student of Marie Curie. In 1939, Perey discovered the element francium by purifying samples of lanthanum that contained actinium. In 1962, she was the first woman to be elected to the French Académie des Sciences, an honor denied to her mentor Curie.

Francium was discovered by Marguerite Perey [5] in France (from which the element takes its name) on January 7, 1939. [6] Before its discovery, francium was referred to as eka-caesium or ekacaesium because of its conjectured existence below caesium in the periodic table. It was the last element first discovered in nature, rather than by synthesis.
Marguerite Perey presented her thesis, L'élément 87: Actinium K, at the Sorbonne, defending her proof that she had discovered the last of the natural elements. The element with atomic number 87 has, ever since, been referred to by the name proposed by Perey, in honor of her native land, "francium". [49]
Francium In 1939, Marguerite Perey, a student of Marie Curie, discovered the element francium by purifying samples of lanthanum that contained actinium. Perey first noticed that the actinium she purified was emitting unexpected radiation. After further study she was able to isolate this new element which she named "francium" for France. [31]

The University of California, Berkeley did not rename its School of Jurisprudence to a School of Law until the state legislature passed a bill in 1947 authorizing UCLA to create a "school of law." Boalt Hall's newly-hired dean, William Lloyd Prosser, got wind of this in 1948 while visiting UCLA to help plan the new law school and decided that ...
