Hazelton debuted on stage as a child when a production at Grover's Theater (now the National Theatre) in Washington, D.C. needed a boy to play a young prince in King John.
In 1910, he was a member of the Columbia Players in Washington, D.C.[1] When the Pasadena Community Playhouse presented Our American Cousin in 1930, Hazelton spoke during intermission of each performance, relating what he witnessed as he observed the assassination.
[2] In 1933, Hazelton gave a lecture at May Company Exposition Hall in Los Angeles and talked about watching Booth shoot Lincoln.
[3] An article in Good Housekeeping in its February 1927 edition, titled "This Man Saw Lincoln Shot," was the basis for a leaflet that Hazleton released to raise funds later in his life.
[5] Hazelton also claimed that Booth was not killed by Union soldier Boston Corbett in a barn in Northern Virginia on April 26, 1865.
