The Larson Brothers Airport was the first airport in Winnebago County and one of the earliest Wisconsin airports. It housed the first Wisconsin agency selling government approved planes, and for 20 years served as a center for state aviators. This well-maintained airport opened in the town of Clayton in 1922, followed by Oshkosh Airport in 1927 and Whiting Airport in the town of Menasha in 1928. Of the three airports, the Larson Brothers Airport is the only one with its original hangar and sod landing field.

Four brothers, Roy, Clarence, Newell and Leonard Larson, developed the airport. They began by creating a grass landing strip behind the barn on their family farm. At first they gave lessons and ran a flying circus, touring county fairs and "barnstorming" throughout the Midwest. In 1924, they built a simple wood-frame six-plane hangar modeled after designs in an aviation magazine, allowing the field to accommodate transient as well as local aviators. They also built and serviced planes, forming the Roy Larson Aircraft Company in 1926. The next year, the brothers incorporated under the name Wisconsin Airways. While modest in size and appearance compared to airports today, the facilities were comparable to metropolitan airports and enjoyed a statewide reputation. By 1932, a Milwaukee Journal reporter lionized the field as the "finest airport in the state."

Ultimately the airport's rural location contributed to its decline. After 1930, sod landing fields gave way to cinder runways, which in turn were paved and lengthened as airplanes increased in size and power. The high cost of improvements caused many small airports to close, the fields returning to farms or lost to city expansion. Rapidly changing technology also transformed metropolitan airports, removing all traces of their modest origins. In the face of these changes, the Larson Brothers Airport continued operation until closed by federal mandate at the outbreak of World War II. Leonard Larson maintained the airport for his family's use.
