A son of the American heartland, Del was born in Linn, Kan. Growing up he called Greenleaf, Kan. his hometown, where he lived with his parents, the late August “Gus” and Gertrude “Gert” (Oestriecht) Bokelman, and brother, Terry Bokelman.

Following his graduation from Greenleaf High School in 1952, he enrolled at Kansas State University, where he was a member of Beta Sigma Psi fraternity. Del completed his Bachelor of Science and Doctor of Veterinary Medicine degrees in 1958 as part of Kansas State’s six-year accelerated baccalaureate/DVM program.

Del married Karen (Carlson) of Ellinwood, Kansas in June of that year, and they moved to the east coast, living in Greenport, New York on the north fork of Long Island, Ithaca, New York and Lansdale, before settling in Doylestown, in 1966, where they raised four children.

Following his graduation from Kansas State, he worked at the Plum Island Animal Disease Laboratory, a US federal research facility off the coast of Long Island, as a Veterinarian, Immunological Investigations.

Shortly thereafter, Del started an eminent, 34 year career at Merck Research Laboratories (MRL) in West Point, Pennsylvania, retiring from there in 1998. During this time he earned a universal reputation as an authority on the safety evaluation of medicinal products. Dr. Bokelman was promoted to Vice President of Safety Assessment in 1989, with duties including other research activities in MRL as well as the Department of Safety Assessment.
