[2] Along with his younger brother, Moe Mark (1872–1932),[3] Mitchel founded the Vitascope Theater (a special attraction of his Edisonia Hall in the Ellicott Square Building), one of the first permanent, purpose-built movie theaters in the world.
[2] Again with his brother, Mitchel founded the Automatic Vaudeville Company in 1904 in New York City.
The Mark brothers eventually built and operated dozens of theaters in the United States.
[8] By 1917, Mark's importance in motion picture exhibition was such that when Cecil B. DeMille complained in his autobiography that exhibitors were protesting the high price of Hollywood movie rentals, he cited Mitchel Mark along with Thomas Lincoln Tally as the worst offenders.
[2] On March 20, 1918, Mark died of an infection at his family's home at 527 Richmond Avenue at the corner of Breckenridge in Buffalo.
