Alma Woodsey Thomas was born in Columbus, Georgia, to an upper-middle-class family. Her family was active in the Black community in town and often hosted art and literary salons. She showed artistic abilities from a young age, creating sculptures and puppets out of clay from the river behind her house.

In 1907, racial violence increased in the South, and at 16, Thomas and her family moved to Washington, DC. She attended the segregated Armstrong Technical High School, where she had her first art class. She aspired to become an architect, and since it was an unusual profession for women at the time, she decided to study kindergarten education instead. In 1914, at 23, she began her 36 years career as a teacher.

In 1921, at the age of 30, Thomas returned to school as a home economics student at Howard University. Soon after, she switched to fine art in the new art department, becoming the first student to graduate the program and probably the first Black woman in the US to earn a bachelor’s degree in art. At 33, with her new specialization, Thomas began teaching art at Shaw Junior High School, leaving for her retirement 36 years later. She also founded a community arts program for children while attending similar programs for adults. In 1930, she began taking summer courses at Columbia University, earning a Master’s in art education at 43 years old. In this period, her art was influenced by the French School of Painting, focusing on landscapes and still-life painted in an impressionist style.

During the 1940s, she was part of The Little Paris Group – a community of Black Washington artists that helped beginner artists improve their techniques. It had inspired her to further her academic education, and for the next ten years, she took night and weekend classes in Art History and Painting at the American University. At the time, her art evolved from figurative painting to abstracts, experimenting with shapes and colors, and she became associated with the Washington Color School – an abstract expressionist art movement.

Over the years, Thomas continued painting, but only after she retired from teaching did she become a full-time professional artist. At 69, she began to translate all the theoretical and practical education she acquired over the decades into her own art with a unique point of view. She became known for her colorful paintings of abstracted shapes and patterns, as can be seen in her series of Earth Paintings, in which she painted abstract circles that reference the rows of azaleas and cherry blossoms that grow in Washington DC.

In 1966, at the age of 75, Thomas had her first retrospective exhibition at Howard University. She continued to create new work, such as the Space series, inspired by the moon landing in 1969 and displaying it in various venues, such as the Corcoran Gallery of Art and the Metropolitan Museum of Art. In 1972 she became the first black woman to have a solo exhibition at the Whitney Museum of American Art.

Thomas died at the age of 87 following aortic surgery.
