David Sinton Ingalls (28 January 1899 – 26 April 1985) was the US Navy's only flying ace of World War I, with six credited victories; thus he was the first ace in U. S. Navy history. He was the son of Albert S. Ingalls; his mother, Jane Taft, was the niece of President William Howard Taft. He was the grandson of railroad executive Melville E. Ingalls. He was the great-grandson of industrialist David Sinton, for whom he was named. He was married to Louise Hale Harkness, daughter of William L. Harkness and granddaughter of Daniel M. Harkness, who was instrumental in the formation of Standard Oil.

Ingalls received his secondary education at the University School in Cleveland, and later attended St. Paul's. He entered Yale in 1916, where he studied as a medical student (he would eventually graduate in 1920 with a BA in English) and joined the First Yale Unit. As such, Ingalls became a member of the Naval Reserve Flying Corps and by 1917 had obtained his pilot's license.

On 26 March 1917, Ingalls was enlisted as Naval Aviator No. 85. He was called to active duty on 4 April 1917. Before heading to Europe, Ingalls received aviation training at West Palm Beach in Florida. On 3 June, he was sent to Huntington, Long Island, New York for more training. His training was completed on 1 September 1917, and he was made a lieutenant (junior grade).
