Margaret Ann Ulle, an advocate for the developmentally disabled, died of an infection Saturday at Roland Park Place. She was 91.
Born Margaret Ann Black in Baltimore and raised in Pittsburgh and Ardmore, Pa., she earned a liberal arts degree at what was then Randolph-Macon Woman's College.
She earned a diploma at Peirce Business College in Philadelphia and returned to Baltimore in 1942 and became secretary to several John Hopkins University presidents. She worked with Isaiah Bowman from 1942 to 1949 and Detlev Bronk from 1949 to 1951.
Family members said that after the birth of her two sons, Wilbur Paul Ulle Jr. and Richard Black Ulle, she devoted her time, as a volunteer, to community services in the field of mental retardation.
She served as president of the ARC Baltimore from 1961 to 1963 and as president of ARC Maryland from 1963 to 1965. Mrs. Ulle was a board member of ARC-National from 1963 to 1967. She served as vice president of the Northeast Region of ARC from 1967 to 1970. She also served as president of Emerge from 1988 to 1992.
In 1970, President Richard M. Nixon appointed Mrs. Ulle to the White House Task Force on Mental Health and Mental Retardation. In 1971, President Nixon appointed her to the President's Committee on Mental Retardation. She was reappointed by President Gerald Ford and served until 1976.
"She was a public speaker and would do anything to fight for special education," said her daughter, Margaret Miriam Ulle of Timonium.
She also served on state boards, including the Advisory Council of Developmental Disabilities, and was chairman of the Citizens Advisory Board of the Henryton Center and of the Citizens Advisory Board of Crownsville Hospital Center. She also served as secretary of the Governor's Commission to Revise the Mental Retardation and Developmental Disabilities Law.
In 1978, she moved to Sherwood Forest, where she became the first female president of the Sherwood Forest Club. During Maryland General Assembly sessions, she served as an administrative aide to Sens. Rosalie S. Abrams and Barbara A. Hoffman for 12 years.
Mrs. Ulle served as first president of the Panhellenic Association of Baltimore and served on the board of the Greater Baltimore WMCA. In 1986, she was given Randolph-Macon's Alumnae Achievement Award. She belonged to the Pi Beta Phi Fraternity.
Services are private.
In addition to her daughter and two sons, who both live in Baltimore, survivors include her husband of 65 years, Wilbur "Bud" Paul Ulle, a retired engineer; and a brother, former U.S. District Judge Walter Black Jr. of Easton.
