Sometimes when seeking out information, I find it best not to work myself into a frenzy trying to pin down every last detail. Part of history is working with the information available, and even with the incredible amounts of information available on the internet (which is how I do most research these days), it is difficult to know everything. Some people have holes in their history.
The basic facts regarding Burnside’s life are fairly easy to find. He died on August 26, 1935 at the age of 47 after a career in aviation that included working with Charles Lindbergh and Will Rodgers. (Rochester Journal Aug 27, 1935). The Nevada Aviation Hall of Fame has a more extensive biography. Burnside was born in Oneonta, New York, on August 7, 1888. He went to college to study music, then became interested in flying in 1911 after seeing a plane at a county fair. He and a friend signed up for classes at the new Thomas Brothers Flying School in Bath, New York, where Burnside eventually became an instructor. The company (and Burnside) moved to Ithica, New York, eventually becoming the Morse Thomas company. During World War I, Burnside served as their chief test pilot. In the 1920 Census, Burnside was living in Ithica. HE often flew in the movies of the Wharton, Incorporated and Grossman Picture Corporation. This was a small movie company based out of Ithica. According to Wikipedia (not the best source, but movie history is not the rabbit hole I am jumping down), the company left Ithica in 1920.
Less information is available about what Burnside was doing between 1920 and 1927, when he flew one of the first legs of the air mail between New York and Chicago after National Air Transport took over that leg of the mail route. The Nevada Aviation Hall of fame doesn’t say anything about this time period. The Post Office says that he began flying in 1923, and flew until 1927 when private corporations took over the service. He was at various times stationed in Maywood and Cleveland. There is no mention of why Burnside chose to fly the mail, and the only mention I have found of him is from a 1924 Omaha World Herald Article that says he was a troubleshooter for the newly instituted night air mail route.
The 1930 Census has Burnside living as a boarder in Rocky River, Ohio. This is located on the west side of Cleveland, a logical place for an aviator to be. Despite the relocation, Burnside kept his New York ties. He died in 1935 in Bath, New York. Burnside’s career with the Post Office was quiet, and, as I said, little is mentioned about him in that context. But he was widely respected as an aviator, and a reminder that it took many people to propel the air mail service forward into the future.
