Isabel Merrick Morgan, PhD
Born: August 20, 1911
Died: August 18, 1996
Morgan's team successfully inoculated monkeys with a killed-virurs vaccine. From 1945-50, her work at Johns Hopkins defined the level of circulating antibodies needed in the blood stream to protect monkeys from an intracerebral challenge from the poliovirus. Her experiments advanced the knowledge needed to develop a viable vaccine.
Brief Biography: Isabel Morgan was born in New Bedford, Massachusetts, the daughter of two accomplished biologists, Thomas Hunt Morgan (who won a Nobel Prize in 1933) and Lilian Vaughan Samson.
Receiving her A.B. from Stanford University in 1932, she pursued her interest in bacteriology and received an M.A. from Cornell University in 1936 and a Ph.D. from the University of Pensylvannia in 1938. She joined the Rockefeller Institute that year and worked with Peter Olitsky, a pioneer in virus research. 1944, she joined David Bodian's poliomyelitis laboratory at the Johns Hopkins University School of Hygiene and Public Health. Morgan left polio research to marry Joesph Mountain in 1944. She died at age 85.

Description of papers: The unprocessed collection of the Isabel Morgan papers in the Alan Mason Chesney Medical Archives (0.25 linear feet) consist mainly of reprints of her published articles and little correspondence. The collection contains two volumes of her publications, as well as unbound reprints and a biographical sketch. The collection is strong in her research on poliomyelitis and the immunization of monkeys against the disease. Additional information on her role in the fight against polio can be found in the David A. Bodian Collection.
