He was supervisor of dirigible operations, liaison to the Navy, pilot and instructor in Key West and Akron at Goodyear's Wingfoot Lake facility from 1917 to 1921.
Gampper was chief pilot of the Wingfoot Air Express, an early Goodyear blimp that was to make history in Chicago on Monday, July 21, 1919, when the worst dirigible disaster in United States history occurred on that date.
The highly flammable hydrogen in the blimp ignited over downtown Chicago causing the airship to crash through the skylight of the Illinois Trust and Savings Building.

It consists of blueprints, manuals, newspaper articles, brochures and photographs of airships and balloons during the early part of the 20th century.
