Marie Bloch

Biography

Bloch was born on 26 July 1902 in Lyon, France. She was born to a Jewish family of five children. Her father, Salomon Bloch, was a watchmaker who immigrated from Hégenheim, Switzerland. He was said to have been the guardian of Lyon's synagogue. The Blochs descended from a Jewish clan that settled in Alsace since the 17th century. Bloch's grandfather decided to move to Lyon when Alsace was occupied by the Germans after the French defeat during the Franco-Prussian War in 1871.

In 1918, Bloch obtained a scholarship to study at the Ecole Technique Municipale (the City Technical School), which was established by the then mayor of Lyon, E. Herriot. She graduated two years later. She obtained a certificate in General Mathematics from the Faculty of Sciences in 1932. She also completed Differential and Integral Calculus, Rational Mechanics, General Physics and Advanced Astronomy.

Bloch started working as an auxiliary staff at the Lyon Observatory. By 1925, she became the official user of the observatory's bent equatorial telescope. A year later, in October 1926, she was officially employed as an assistant astronomer under the leadership of Jean Dufay. During the Second World War, Bloch was forced to abandon her work for being Jewish. She spent years in hiding with the help of Maurice Durvis, who got her employed in a coal purchasing company. After the war, she resumed work at the observatory.

Bloch died on August 1, 1979, in Meyzieu.
