14274 Landstreet           Discovered 2000 Jan. 29 by Spacewatch at Kitt Peak.
John Darlington Landstreet (b. 1940) is on the faculty at the University of Western Ontario. He helped discover magnetic fields in white dwarf stars and developed Balmer-line polarimetry for detection of magnetic fields in middle-main sequence stars.
