Allen was born Tina Powell in Hempstead, New York in 1949 to father Gordon "Specs" Powell, a jazz drummer who played in the Ed Sullivan Show band, and Grenada-born Rosecleer Powell.[1] Her mother was a writer and a nurse, and one of Allen's uncles was a sculptor. Allen began painting at 5 years old; by the time she was 10 she was setting up her easel to paint the seascape of Grenada, West Indies where she lived until her early teens.[2] Allen's parents divorced when she was young. She lived with her mother for four years. While living with her mother in New York city, she met a sculptor by the name of William Zorach who later on became her mentor.[3]
Allen was an artistic child who began sculpting at the age of 13, when she was assigned to make an ashtray and instead created a bust of Aristotle.[4] She was mentored by the Lithuanian-American sculptor William Zorach who declared her a prodigy.[4] She earned a bachelor of fine arts degree from the University of South Alabama in 1978.[1] She also studied at the School of Visual Arts in Manhattan and received her Masters at the Pratt Institute.[2]
People described her art as a history in bronze because she always focused on important black historical figures and wanted to portray them through sculpture.[5] Allen often focused on the Harlem Renaissance. She also had periods of her work focus specifically on black men and then she turned her interest to black women.[5]
After college she volunteered for AmeriCorps VISTA and for several years hosted a local television show on the arts in Mobile, Alabama.[6]
Over the next two decades Allen continued creating realistic sculptures of black activists for display in public spaces. Her work is also collected by museums, corporations and private collectors.[1] Explaining her motivation, she said in an interview, "My work is not about me, it's about us."[8] Not only does her work serve to emphasize the contributions and aspirations of the African Diaspora but also works to create a "visual landscape that is nurturing and life affirming to people of color" in celebrating the beauty of African Americans.[4]
Allen was married twice and had three children, Koryan, Josephine, and Tara. She died of a heart attack due to complications of pneumonia in Los Angeles on September 9, 2008.[6]
