Irene Kaminka Fischer (born July 27, 1907 in Vienna, died October 22, 2009 in Boston) was a mathematician, geodesist, National Academy of Engineering Member; Fellow International Geophysical Union, Inductee of the National Imagery and Mapping Agency Hall of Fame.
Fischer became one of two internationally known women scientists in the field of geodesy during the golden age of the Mercury and Apollo moon missions.
Her Mercury Datum, or Fischer Ellipsoid 1960 and 1968, as well as her work on the lunar parallax, were instrumental in conducting these missions.
"In his preface to the ACSM publication, Fischer's former colleague, Bernard Chovitz, referred to her as one of the most renowned geodesists of the third quarter of the twentieth century.
Yet this fact alone makes her one of the most renowned geodesists of all times, because, according to Chovitz, the third quarter of the twentieth century witnessed "the transition of geodesy from a regional to a global enterprise."
