Margaret Merrell

Margaret Merrell (December 3, 1900[1] – 21, 1995)[2] was an American biostatistician who taught at Johns Hopkins University for many years[3] and became the first female full professor in the Johns Hopkins School of Public Health.[4] She is known for her research with Lowell Reed on the construction of life tables.[3][5] She also observed that, for longitudinal data on individuals, fitting a curve to each individual and then averaging the parameters describing the curve will typically give different results than averaging the data values of the individuals and fitting a single curve to the averaged data.[6]

Merrell was born in La Grange, Illinois.[2] She entered Wellesley College as an honor student from Framingham High School,[7] and became vice-president of the Wellesley mathematics club.[8] She graduated in 1922, and took a position as a schoolteacher in Baltimore.[9] She joined Johns Hopkins as an instructor and graduate student in 1925, and completed her Sc.D. there in 1930.[3] Her dissertation, supervised by Lowell Reed, was The Relationship of Individual Growth to Average Growth.[10]

After completing her doctorate, Merrell remained on the Johns Hopkins faculty.[3] During World War II, she consulted with the U.S. Army on treatments for sexually transmitted diseases and for motion sickness.[9] As a faculty member at Johns Hopkins, she "reportedly carried most of her department's teaching load"[11] and was described as "the intellectual power behind the throne" of the department.[3] She was promoted to full professor in 1957,[4] served as acting chair of biostatistics in 1957–1958, and retired in 1959.[3][4] She died in 1995, in a nursing home in Berlin, New Hampshire.[2]

She was honored by the American Statistical Association in 1951 by election as a fellow of the association.[12]
