(4140) Branham is a main belt asteroid that was discovered on November 11, 1976 at Argentina's El Leoncito Observatory, a branch of the Felix Aguilar Observatory . Subsequently, the asteroid could already be detected on recordings made in 1929 at the Crimean Observatory in Simejis and in 1952 at the McDonald Observatory in Texas .
The asteroid was named after the American astronomer Richard L. Branham, Jr. , who deals with meridian astronomy and celestial mechanics . He worked on the passage instrument of the United States Naval Observatory in Washington, DC from 1968 to 1982 , then went to Argentina and became director of the Yale-Columbia Southern Station in Leoncito.
