In 1921, Julian left Montreal for good and moved to Harlem. Once there he came under the influence of the charismatic Marcus Garvey and joined the Universal Negro Improvement Association. This new "Garveyvite" soon adopted a new persona, rechristening himself "Lieutenant Hubert Julian" of the Royal Canadian Air Force. Julian had a tailor fashion for him a fake military uniform in order to push his new narrative. On 3 September 1922, Julian performed his first parachute jump at Curtiss Field on Long Island; the event was headlined with a flight by Bessie Coleman. Julian would make one more jump that year before teaming up with aviator Clarence Chamberlin who, in addition to teaching his new business partner how to truly handle an airplane, flew him up above Harlem where the Trinidadian parachuted several times, the most famous moment coming when he wore a crimson jumpsuit while playing "Runnin' Wild" on a saxophone. This would be the stunt which caused H. Allen Smith to dub Julian "The Black Eagle of Harlem". Julian also parachuted over Harlem while playing a gold-plated saxophone in October 1923.
