Calloway was the first African American to receive an academic doctorate from an institute west of the Mississippi River and the first African American to receive a PhD in chemistry from Iowa State University (ISU).

Early life and education

Calloway was born on October 10, 1907 in Tuskegee, Alabama. He was one of five children born to his father James N Calloway, who was a former slave and his mother Marietta Oglesby.

He studied at Iowa State University and completed his B.S in 1930. Three years later, in 1933, he became the first African American to earn his Ph.D. in Organic Chemistry. Henry Gillman was Calloway's Ph.D. advisor at Iowa State University. He was one of the few African American chemistry majors Gillman helped obtain their doctorates at ISU. Once he received his doctorate he led the department of chemistry at Tuskegee Institute from 1933 to 1935. Following in his father's foot steps, he became an assistant professor in Fisk University’s Chemistry Department. He taught in Fisk University's chemistry department until 1940.

Dr. Calloway continued his passion for knowledge and discovery and earned his M.D. degree from the University of Illinois in 1943. Calloway served as an assistant professor at the University of Illinois Medical School and worked as a practicing physician and earned a specialist degree in Internal Medicine. Between 1944 and 1947 he did significant studies as the director of a US Naval project. In 1946, he published approximately 17 papers and had four more in process. His research was in chemistry, pharmacology and internal medicine. In 1947, Calloway rose from assistant to senior professor at University of Illinois Medical School and he served as Medical Director at Provident Hospital where he remained for two years. He created the Medical Associates of Chicago, composed of 12 doctors who worked with state of the art equipment.

Author, Chemist, Physician, Scientist, and Civil Rights Activist, he was a pioneer in the field of chemistry. Calloway was an organic chemist, physician, military officer, and educator. Immediately after getting his Ph. D., Calloway became head of the chemistry department at the Tuskegee Institute in Alabama. Calloway was also a professor at the University of Illinois Medical School and wrote more than 30 scientific articles and publications in scientific journals. He served as a medical director of Provident Hospital in Chicago until 1949, and then founded the Medical Associates Clinic of Chicago.

He became Chief of the Medical Staff at the Tomah Wisconsin Veterans Administration Hospital in 1963. He then opened a private practice in Madison in 1966.

Calloway studied synthetic organic chemistry, a branch of chemistry that focuses on compounds that contain the element carbon. He also had a passion for writing Calloway published several peer-reviewed articles in top chemistry journals such as the Journal of the American Chemical Society.

While still practicing medicine in Chicago in the 1950s, he built a 400 acre showplace in Wisconsin, the Grand Marsh Wildlife Ranch, where wild and domestic animals that were kept in large, natural habitats.

He continued to volunteer his time with the Tuskegee Institute and with Iowa State until his death from cancer in 1979.
