The Department of Astronomy at the University of California, Los Angeles (UCLA) has its origins in the 1922 appointment of
Frederick C. Leonard, an astronomer, to the Department of Mathematics. In 1931, a separate Department of Astronomy was created.
The initial focus of the department was on meteoritics, followed by celestial mechanics, and interplanetary navigation. In
the 1950s, the department expanded to include instruction in stellar astronomy and astrophysics.
