11766 Fredseares           Discovered 1960 Oct. 17 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Frederick H. Seares (1873-1964) was an American astronomer who standardized the stellar magnitude system and extended it using photography at Mt. Wilson Observatory. He measured and interpreted color indices of stars.
