Arlo Udell Landolt (born September 29, 1935) is an American astronomer.[1] Landolt has worked principally in photometry and has published a number of widely used lists[2][3][4] of standard stars.[5][6] In 1995, he received the George van Biesbroeck Prize from the American Astronomical Society.[7] Landolt was the first discoverer of a pulsating white dwarf when he observed in 1965 and 1966 that the luminosity of HL Tau 76 varied with a period of approximately 12.5 minutes.[8] The asteroid 15072 Landolt is named after him.[6]


Arlo Landolt graduated from Highland High School in 1952. He received his Ph.D. in 1962 from Indiana University.[5]
