William A. "Pat" Patterson (October, 1899 — June 13, 1980) was the President of United Airlines from 1934 until 1966.
Patterson was born on a sugarcane plantation in Waipahu on Oahu, Hawaii. When Patterson was 13, his widowed mother moved to San Francisco, California, while he remained at Honolulu Military Academy. Not liking the academy, he decided to leave. He persuaded a captain to allow him to work on his ship in exchange for passage to San Francisco.
Instead of finishing high school in San Francisco, Patterson became an office worker at Wells Fargo bank, though he later attended night school. He became a teller and later a loan officer.
As a loan officer, he authorized a loan to Pacific Air Transport and became an advisor to its founder and president Vern Gorst. When Gorst sold his airline to Boeing Air Transport, the advice that Gorst was receiving from Patterson brought the latter to the attention of Philip G. Johnson of Boeing.
Patterson was recruited by Johnson, leaving Wells Fargo in 1929, and moving to Seattle, Washington, to be the assistant to the president of Boeing Airplane Company and Boeing Air Transport. In 1931 Boeing Air Transport was one of four airlines that merged into United Air Lines and Patterson moved to Chicago to become United's general manager.
Two years later, Patterson was promoted to vice president of United. In 1934, in reaction to the Air Mail scandal and the departure of Johnson, Patterson became the company's president at the age of 34.
Patterson is credited with starting the profession of flight attendant. He gave his approval to hire eight nurses to work as flight attendants on a three-month trial basis. On May 15, 1930, United became the first airline to use flight attendants, a practice that has since been adopted by every major airline. Patterson's daughter, Patty, briefly worked for American Airlines as a flight attendant before her marriage rendered her ineligible. Patterson and C. R. Smith, the CEO of American, shared a friendly rivalry.
