Nadine Jeppesen was hired by United Airlines as a "stewardess" to tend to passengers aboard its flights. In 1936, she married Capt. Jeppesen and together they established a flight chart business, producing the Jeppesen Airway Manual. Working out of the basement of their home in Salt Lake City, Utah, Nadine hired cartographers, helped design and write the copy for promotional procedures, and handled a myriad of other details associated with running the company. She continued to work as secretary/treasurer after they moved to Denver in 1941, and held that position until the company was sold in 1961. Nadine died in 1996.
