Hope Tisdale Eldridge
Dorothy Hope Tisdale Eldridge (June 18, 1904 – October 5, 1991) was an American physical educator, demographer, and statistician. Early life and education 
Hope Tisdale was born in Mobile, Alabama, the daughter of Marion Eugene Tisdale and Helen M. Sturtevant Tisdale. She graduated from Barnard College in 1925. She trained for a career as a physical educator at the Boston Central School of Hygiene and Physical Education. She later completed a master's degree at New York University in 1935, and doctoral studies in sociology at the University of North Carolina at Chapel Hill in 1942. Her doctoral thesis was titled "Urbanization: A Study of the Process of Population Concentration in the United States and its Relation to Social Change". Career 
Tisdale taught physical education at the University of North Carolina at Greensboro from 1927 to 1938. In the 1930s she worked with the Works Progress Administration in North Carolina, and became interested in demography and statistics. Pursuing that interest, she took a job as an analyst with the United States Census Bureau from 1942 to 1947, and then with the Food and Agriculture Organization of the United Nations. She was editor of the UN's Demographic Yearbook beginning in 1950. In 1952, Tisdale became a target of the Internal Security Subcommittee of the United States Senate Judiciary Committee, and her refusal to cooperate with their questions led to her dismissal from the UN. She later sued, and was awarded compensation from the United Nations for her firing. She taught sociology at the University of Tampa in 1958. Selected publications
