Jeppesen (1934 - present)

Jeppesen (1934 - present), originally Jeppesen and Company, is a Colorado-based company offering products and services related to aeronautical navigation and operations. Founded by aviation pioneer Elrey Borge Jeppesen and with important contributions from his wife, Nadine Jeppesen, a leading female figure in the early history of aviation, the company established a reputation in the mid-20th century for high-quality aeronautical navigation charts. By the 1970s, the company had expanded to other countries and adopted innovative methods, employing computers in navigation and flight planning. It was purchased several times by larger companies, including eventually by Boeing, while also undertaking its own acquisitions.
