Bailey.[5] He opened the first Black-led architecture firm in downtown Chicago,[4] and by 1940, he was a licensed architect in the state of Illinois. In 1937, Beverly Lorraine Greene had briefly worked for O'Neal's architecture firm, and he had served as one of her mentors.[4][8] Georgia Louise Harris Brown, the second African American woman to become a licensed architect in the United States, had also worked at the firm of O'Neal from 1945 to 1949.[1][9][6] Architect John Moutoussamy had also been mentored by O'Neal and worked at the firm.[5] O'Neal published two design books: "A Portfolio of Modern Homes" (1949),[10] and "A Volume of Contemporary Homes" (1980).
He retired in 1983.[2] O'Neal had married three times.[1] After retirement, he moved to Tucson, Arizona, followed by a move to Honolulu, Hawaii. He died at age 80 on March 17, 1989, in Honolulu.[11]
