Lindsley, William D.
 
William D. Lindsley of Waynoka, Oklahoma, invented several everyday items, including fishhooks and flyswatters. In 1909 he began experimenting with aircraft designs. His first design was called the Oklahoma Monoplane; a sketch of which appeared in the Waynoka Democrat newspaper on March 5, 1909. In January 1910, he applied to the Unites States Patent Office for a patent on his flying machine, which was eventually granted on September 5, 1911.
