Arthur Froehlich was born in 1909 in Los Angeles; his father was a cattle and dairy farmer. He attended the University of California. His first job was as a draftsman for the structural engineer working on Santa Anita racetrack. That sparked an architectural practice designing racetracks. In addition to Hollywood Park, they include Aqueduct Racetrack (1958) in New York, Belmont Park (1967) in New York (a job he won over Frank Lloyd Wright's NY office), Keeneland in Kentucky, Golden Gate Fields, Garden State Park and the Hipodromo La Rinconada National Track(1959) in Caracas. Other buildings include the parking structures at UCLA, Jack Rose Building in Ventura which was demolished and the Hanna Barbera Studios in Los Angeles. He died in 1985.
