That question should result in some interesting answers!
I think you are refering to Gustave Whitehead who allegedly on August 14, 1901, in Fairfield, Connecticut, reportedly flew his engine-powered Number 21 800 meters at 15 meters height. No photographs exist of this flight, but a sketch was made by one of the many witnesses.
There is also talk the first flight was by a twenty-five year old New Zealander, Richard Pearse on March 31, 1902 in Waitohi, New Zealand just near Timaru.
