Hattie McDaniel (standing, center right), the first African American to win an Oscar won in 1940 for her supporting role as Mammy in "Gone with the Wind," performed with the George Morrison Orchestra in the 1920s. While attending Denver's East High School in the early 1900s, McDaniel started professionally singing, dancing and performing skits in shows as part of her family’s Vaudeville act, The Mighty Minstrels. She dropped out of high school in 1909 to focus on her singing and dancing. The George Morrison Orchestra sometimes played at the Albany Hotel, which had not previously allowed performances by African American musical groups. Photo circa 1928.
