Robley Cook Williams (October 13, 1908 – January 3, 1995) was an early biophysicist and virologist. He served as the first president of the Biophysical Society.

Nevin Stewart Scrimshaw (January 20, 1918 – February 8, 2013) was an American food scientist and Institute Professor emeritus at the Massachusetts Institute of Technology. Scrimshaw was born in Milwaukee, Wisconsin. During the course of his long career he developed nutritional supplements for alleviating protein, iodine, and iron deficiencies in the developing world. His pioneering and extensive publications in the area of human nutrition and food science include over 20 books and monographs and hundreds of scholarly articles. Scrimshaw also founded the Department of Nutrition and Food Science at the Massachusetts Institute of Technology, the Institute of Nutrition of Central America and Panama, and the Nevin Scrimshaw International Nutrition Foundation. He was awarded the Bolton L. Corson Medal in 1976 and the World Food Prize in 1991. Scrimshaw spent the last years of his life on a farm in Thornton, New Hampshire, where he died at 95.

Robert Paul Kraft (June 16, 1927 – May 26, 2015) was an American astronomer. He performed pioneering work on Cepheid variables, stellar rotation, novae, and the chemical evolution of the Milky Way. His name is also associated with the Kraft break: the abrupt change in the average rotation rate of main sequence stars around spectral type F8.

Elizabeth Duncan Koontz (June 3, 1919 – January 6, 1989) was a national figure in education, civil rights and the women's movement. She was the first African-American president of the National Education Association and director of the United States Department of Labor Women's Bureau.

Harold Lester Johnson (April 17, 1921 – April 2, 1980) was an American astronomer.
Harold Johnson was born in Denver, Colorado, on April 17, 1921. He received his early education in Denver public schools and went to the University of Denver, graduating with a degree in mathematics in 1942. Johnson was recruited by the MIT Radiation Laboratory to work on World War II related radar research. After the war Johnson began graduate studies in astronomy at University of California, Berkeley where he completed his thesis under Harold Weaver in 1948.
In the following years working at Lowell Observatory, University of Wisconsin–Madison, Yerkes Observatory (where he met William Wilson Morgan), McDonald Observatory, University of Texas–Austin, the Lunar and Planetary Laboratory in Tucson, Arizona, and the National Autonomous University of Mexico he applied his instrumental and electronic talents to developing and calibrating astronomical photoelectric detectors.
He died of a heart attack in Mexico City in 1980. He and his wife, Mary Elizabeth Jones, had two children.
Johnson was awarded the Helen B. Warner Prize by the American Astronomical Society in 1956. He was elected to the National Academy of Sciences in 1969. He is remembered for introducing the UBV photometric system (also called the Johnson or Johnson-Morgan system), along with William Wilson Morgan in 1953.

Francis Clark Howell (November 27, 1925 – March 10, 2007), generally known as F. Clark Howell, was an American anthropologist.
Born in Kansas City, Missouri, F. Clark Howell grew up in Kansas, where he became interested in natural history. He served in the U.S. Navy during World War II, from 1944 to 1946 in the Pacific Theater. Howell was educated at the University of Chicago, where he received his Ph.B., A.M. and Ph.D. degrees under the tutelage of Sherwood L. Washburn.
Dr. Howell died of metastatic lung cancer on March 10, 2007, at age 81 at his home in Berkeley, California.

Arthur Davis Hasler (January 5, 1908 – March 23, 2001) was an ecologist who is credited with explaining the salmon's homing instinct. Hasler was a member of the National Academy of Sciences and the American Academy of Arts and Sciences. The New York Times called him "an internationally recognized authority on freshwater ecology". He served as President of The Ecological Society of America, which called him "one of the leading figures in 20th century freshwater ecology". Hasler pioneered a research method based on manipulation of entire lake ecosystems. This method became an instrumental new tool for ecology. He published over 200 scientific papers, was an author or an editor of 7 books, and supervisor of 52 doctoral degrees.

Chauncy Dennison Harris (1914 - December 26, 2003) was a pioneer of modern geography. His seminal works in the field of American urban geography ("The Nature of Cities" and "A Functional Classification of Cities in the United States") along with his work on the Soviet Union during and after the Cold War era established him as one of the world's foremost urban geographers. He also made significant contributions to the geographical study of ethnicity, specifically with respect to non-Russian minorities living within the Soviet Union. Harris traveled regularly to the Soviet Union and played a key role in establishing a healthy dialog between Soviet and American scholars.

Robert Minard Garrels (August 24, 1916 – March 8, 1988) was an American geochemist. Garrels applied experimental physical chemistry data and techniques to geology and geochemistry problems. The book Solutions, Minerals, and Equilibria co-authored in 1965 by Garrels and Charles L. Christ revolutionized aqueous geochemistry.
Garrels earned a bachelor's degree in geology from the University of Michigan in 1937. He went on to earn an M.S. degree from Northwestern University in 1939, his thesis work was on iron ores of Newfoundland in 1938. His Ph.D. was awarded in 1941 based on lab studies of complex formation between lead and chloride ions in aqueous solution.
