Georges César Tiercy (1886–1955) was a Swiss astronomer and the 7th director of the Observatoire de Genève [1] from 1928 to 1956.
Tiercy received his bachelor of science degree in 1913 from the University of Paris and his Ph.D. in science and mathematics from the University of Geneva in 1915. He was a master in a private college in Ouchy from 1908 to 1912. He taught mathematics in various schools in Geneva from 1913 to 1927 and was a privat-docent at the University of Geneva from 1915. After an internship at the observatories of Hamburg in 1927 and of Arcetri in Florence in 1927–1928, Tiercy became director of the observatory of Geneva in 1928. At the University of Geneva he was professor ordinarius of astronomy from 1928 to 1950 and rector from 1948 to 1950. At the University of Lausanne he was professor extraordinarius of astronomy from 1936 to 1953 and professor ordinarius from 1953 to 1955. He was the author or co-author of more than 250 papers. [2]

He did research on theoretical physics, astrophysics, geodesy, meteorology and chronometry.
