In 1919, a young aviator lieutenant named Albert Plesman sponsored the ELTA aviation exhibition in Amsterdam. The exhibition was a great success; after it closed several Dutch commercial interests intended to establish a Dutch airline, which Plesman was nominated to head. In September 1919, Queen Wilhelmina awarded the yet-to-be-founded KLM its "Royal" ("Koninklijke") predicate.On 7 October 1919, eight Dutch businessmen, including Frits Fentener van Vlissingen, founded KLM—the abbreviation of Koninklijke Luchtvaart Maatschappij ("Royal Aviation Society") as one of the first commercial airline companies. Plesman became its first administrator and director.
