Sterling Gaylen Bradley

Born April 2, 1932, in Springfield, Missouri, Bradley went to Missouri State University where he completed his undergraduate studies in 1950 majoring in biology and chemistry. He pursued a master’s degree and a Ph.D. in microbiology at Northwestern University in Illinois, where he worked with Maurice Sussman in the biological sciences department on characterization of chemical and physical environment of the soil-dwelling eukaryotic organism Dictyostelium discoideum. He went to the University of Wisconsin in 1954 as a postdoctoral fellow under Joshua Lederberg and developed an interest in Streptomyces bacteria, the largest genus of Actinomycetota.

Following his postdoctoral study and a short stint as an instructor, Bradley was hired in 1957 as an assistant professor at the University of Minnesota where he continued to study the taxonomy of actinophage. After he became a full professor, he shifted to Medical College of Virginia at Virginia Commonwealth University in 1968 as a professor and chair of Department of Microbiology and Immunology and continued till 1996 when he retired and was named dean emeritus of the School of Basic Health Sciences.

Bradley’s research interests covered a wide area of bacterial lipopolysaccharide, interaction between bacterial endotoxin and therapeutic drugs, biology of the so-called brain-eating amoeba Naegleria fowleri and immunotoxicology. He had more than 200 publications with almost 3,000 citations.

Bradley held several prestigious academic positions during his career. He was the vice president for academic affairs at the University of Maryland Biotechnology Institute from1996 to 1999 and a visiting professor and interim director at Penn State University from 1999 to 2012. As a consultant, author and lecturer, he promoted global outreach programs, research integrity, public science education and science policy.

A longtime member of the 91ÑÇÉ«´«Ã½, Bradley had a letter published in the September 2005 issue of 91ÑÇÉ«´«Ã½ Today titled “‘Intelligent Design’ does not belong in the science classroom.”

Bradley was known as a committed mentor to people at all stages of their education and careers, according to a . In addition to guiding doctoral candidates and junior faculty, he hosted international students through Rotary International and was a leader in Boy Scouts and Indian Guides.

Bradley is survived by his wife, former 91ÑÇÉ«´«Ã½ president Judith Bond; four children and their spouses; eleven grandchildren; and seven great-grandchildren.
