Established by educator Marion Kingsbury in 1938, Kingsbury is the oldest nonprofit educational organization to address the needs of children and adults with learning disabilities and differences in the Washington, D.C. area.
In September 1938, Marion Kingsbury founded The Remedial Education Center with two colleagues. Mrs. Kingsbury led the first tutor-training course that fall, and the center began tutoring children with reading difficulties. Early on, she recognized that "remedial" students were quite often as intelligent as their classmates, and she worked to educate parents and teachers about learning difficulties. In the late 1940s, Mrs. Kingsbury founded the National Association of Remedial Teachers to unite and educate teachers of students with learning difficulties. The center began offering diagnostic testing for children in the fall of 1946, utilizing the team approach that the center maintains today.
When Marion Kingsbury retired as director in 1964, the Board of Trustees voted to change the name of the organization from The Remedial Education Center to The Kingsbury Center in her honor.
