126445 Prestonreeves           Discovered 2002 Feb. 7 by J. V. McClusky at Kingsnake Observatory.
W. Preston Reeves (b. 1935), chemistry professor emeritus, Texas Lutheran University, helped found the department and taught students organic chemistry for over 30 years. More than 120 of these students received advanced degrees. He also made research contributions in phase-transfer catalysis.
