Monrovia is the discoverer's hometown. Nestled in the foothills NE of Los Angeles, California, it is known for its all-American small-town atmosphere, historic homes (including the Upton Sinclair House), classic cars, and its charming warm historic Mayberry-like downtown. It is called the “Gem City of the Foothills” and home to the famous “Big M”.Naming citation (WGSBN Bull. 3, #16, 4), IAU / Minor Planet Center, via NASA/JPL
