After college she moved to
Washington, D.C., where she taught music at the
Lucretia Mott Elementary School and at
Howard University. Her experience at the Mott school convinced her of the need for free kindergarten and for special training for kindergarten teachers. Starting in 1895, as chair of the Education Committee of the
National League of Colored Women (NLCW), she campaigned for the establishment of free kindergarten classes for black children in Washington D.C. The League established six or seven local kindergartens, and in October 1896, she took over the management of a
normal school founded by the NLCW to train kindergarten teachers. In 1898, she successfully lobbied Congress for federal funds to introduce kindergarten classes to the Washington D.C. public school system; it was the first time federal funds had been allocated for kindergarten education. That same year, she and Sara I. Fleetwood represented the NLCW at the
National Congress of Mothers, a convention in Washington D.C. that led to the formation of the
Parent-Teacher Association (PTA). At the convention she met the philanthropist
Phoebe Hearst, and persuaded her to fund the Kindergarten Training School for five years. In 1906 she again secured federal funding, this time for kindergarten teacher training classes at the
Miner Normal School. In the 1900s she directed the kindergarten program at the Colored
Settlement House (also known as the Social Settlement), whose leadership included
Anna J. Cooper,
Francis J. Grimké, and
Mary Church Terrell. She became nationally known as an advocate for kindergarten education, and local groups frequently sought her advice. In 1904 she published an article in the
Southern Workman in which she recommended
starting the education of children long before the age of six, which was then the legal age for children to start public school. She believed nursery schools should be part of the public school system, and continued to advocate for them throughout her career. She also wrote historical articles and contributed to her husband's
Historical and Biographical Encyclopedia of the Colored Race. On March 3, 1913 she was one of less than 100 black women who bravely marched in the Woman's suffrage parade. While in her seventies, she lobbied Congress for a health center to combat tuberculosis, and for land to be converted to playgrounds near two local elementary schools. She was vice president of the Public School Association, an officer of the Association for Childhood Education, and a member of the NAACP, the Citizens Advisory Committee on Hot Lunches for School Children, the
YWCA, and
St. Luke's Episcopal Church. == Personal life ==
