Frederick C. Leonard
Frederick Charles Leonard (March 12, 1896 – June 23, 1960) was an American astronomer. As a faculty member at the University of California, Los Angeles, he conducted extensive research on double stars and meteorites, largely shaping the university's Department of Astronomy. He received his undergraduate degree from the University of Chicago in 1918 and his PhD in astronomy from the University of California at Berkeley in 1921. Leonard was an astronomer from his teenage years, founding the Society for Practical Astronomy in 1909. In 1923 he founded The Society for Research on Meteorites, which later became known as the Meteoritical Society. In 1933 he became its first president and was the Editor of the Society's journal for the next 25 years. The Society instituted the Leonard Medal in 1962, its premier award for outstanding contributions to the science of meteoritics and closely allied fields.
==Early life==
Leonard was born in Mount Vernon, Indiana in 1896 and moved with his family to Chicago in about 1900, eventually settling near the University of Chicago. From the age of eight, he showed great interest in the stars and by early adolescence had become an active amateur astronomer. In 1909 he attended the annual meeting of the Astronomical and Astrophysical Society of America, held at the Yerkes Observatory. The same year, he organized the Society for Practical Astronomy (SPA), a national amateur organization. Leonard's leadership raised concerns among professional astronomers〔 as not all were in favor of amateur contributions to the profession. Nonetheless, the organization flourished until Leonard's departure in 1919.〔(California Digital Library ), Frederick Charles Leonard, Astronomy: Los Angeles.〕
Leonard was a prolific writer and by the age of 14 had attracted the attention of numerous publishers. He authored a year-long series of articles titled "Mr. Leonard's Star Colors" in the English Mechanic and World of Science.〔 A Chicago Tribune reporter characterized him as a "co-worker with such savants as Prof. F. R. Moulton"〔 and Francis P. Leavenworth.
After graduating from Hyde Park High School in Chicago, Leonard completed his bachelor's and master's degrees at the University of Chicago. He continued his graduate education at the University of California, Berkeley with Armin Leuschner, being awarded his PhD in 1922 for his thesis "An Investigation of the Spectra of Visual Double Stars".
