The role of a flight attendant derives from that of similar positions on passenger ships or passenger trains, but it has more direct involvement with passengers because of the confined quarters on aircraft. Additionally, the job of a flight attendant revolves around safety to a much greater extent than those of similar staff on other forms of transportation. Flight attendants on board a flight collectively form a cabin crew, as distinguished from pilots and engineers in the cockpit.
The German Heinrich Kubis was the world's first flight attendant, in 1912. Kubis first attended the passengers on board the DELAG Zeppelin LZ 10 Schwaben. He also attended to the famous LZ 129 Hindenburg and was on board when it burst into flames. He survived by jumping out a window when it neared the ground.
Origins of the word "steward" in transportation are reflected in the term "chief steward" as used in maritime transport terminology. The term purser and chief steward are often used interchangeably describing personnel with similar duties among seafaring occupations. This lingual derivation results from the international British maritime tradition (i.e. chief mate) dating back to the 14th century and the civilian United States Merchant Marine on which US aviation is somewhat modeled. Due to international conventions and agreements, in which all ships' personnel who sail internationally are similarly documented by their respective countries, the U.S. Merchant Marine assigns such duties to the chief steward in the overall rank and command structure of which pursers are not positionally represented or rostered.
Imperial Airways of the United Kingdom had "cabin boys" or "stewards"; in the 1920s. In the US, Stout Airways was the first to employ stewards in 1926, working on Ford Trimotor planes between Detroit and Grand Rapids, Michigan. Western Airlines (1928) and Pan American World Airways (Pan Am) (1929) were the first US carriers to employ stewards to serve food. Ten-passenger Fokker aircraft used in the Caribbean had stewards in the era of gambling trips to Havana, Cuba from Key West, Florida. Lead flight attendants would in many instances also perform the role of purser, steward, or chief steward in modern aviation terminology.
The first female flight attendant was a 25-year-old registered nurse named Ellen Church. Hired by United Airlines in 1930, she also first envisioned nurses on aircraft. Other airlines followed suit, hiring nurses to serve as flight attendants, then called "stewardesses" or "air hostesses", on most of their flights. In the United States, the job was one of only a few in the 1930s to permit women, which, coupled with the Great Depression, led to large numbers of applicants for the few positions available. Two thousand women applied for just 43 positions offered by Transcontinental and Western Airlines in December 1935.
