Best known as a coauthor of Whole Body Counters, he helped explain radiation science in a clear, practical way during the early atomic age. His career bridged research, teaching, and public-facing scientific writing.

by John H. Woodburn, F. W. (Frederick W.) Lengemann
Frederick W. Lengemann was an American scientist and educator whose work centered on radiation biology and physiology. In the 1960s, he was an associate professor of radiation biology at the New York State Veterinary College at Cornell University, and Whole Body Counters introduced general readers to the science and uses of radiation-detection equipment.
Biographical notes published with that book say he earned his B.S. and M.N.S. from Cornell University and his Ph.D. from the University of Wisconsin. They also note earlier roles as a research associate in radiation biology and as an assistant professor of chemistry at the University of Tennessee, along with work as a biochemist for the Atomic Energy Commission.
Later accounts describe a long Cornell career: after joining the university in 1959, he served for decades in physiology and became Professor Emeritus in 1988. An obituary reports that he was born in 1925 and died in 2013, and that his professional life also included international consulting and training work connected with agriculture and nuclear science.
