Augustus Roy Knabenshue (July 15, 1876 – March 6, 1960) was an American aeronautical engineer and aviator.

[3] In 1904, at the Louisiana Purchase Exposition, Roy Knabenshue piloted Thomas Scott Baldwin's California Arrow dirigible to a height of 2,000 feet (610 m) and was able to return to the takeoff point.

[4][5] Knabensue continued working for Baldwin for the next year, operating the Californian Arrow at events around the country.

According to writer Charles Taylor, author of the 1948 article reporting the story, Knabenshue talked Wilbur out of disposing of the machine for historical purposes.
