Kasper was born April 27, 1935, in Illinois. As a high school senior, he joined the Navy Reserve and served for eight years. He studied chemistry at the University of Illinois Urbana–Champaign, then transferred to the University of Illinois Chicago College of Pharmacy, graduating in 1958. He received a scholarship for graduate school at the University of Wisconsin–Madison, where he worked in Harold Deutsch’s lab and earned his Ph.D. in physiological chemistry in 1962. With a National Institutes of Health fellowship, he pursued postdoctoral studies at the University of Utah and then at UCLA, where he was hired as an assistant professor.

When he was offered his own lab at the McArdle Laboratory, Kasper moved with his family in 1965 to Madison, Wisconsin and remained there until he retired, establishing a successful research program, teaching graduate-level oncology and toxicology courses, and mentoring undergraduates, medical and doctoral students, and postdoctoral fellows for 38 years.

Kasper studied proteins of the endoplasmic reticulum and nuclear envelope. His research focused on understanding the biochemical regulation of enzymes involved in the metabolism of chemical carcinogens, including NADPH-cytochrome P450 reductase and epoxide hydrolase. His lab discovered the CYP3A gene family and pioneered understanding its contribution in the metabolism of numerous endogenous compounds and more than half of all prescription drugs. Throughout his career, he had uninterrupted research funding from the NIH and other organizations, and he was an author on more than 100 peer-reviewed articles.

For many years, Kasper served on the editorial boards of the Journal of Biological Chemistry and Chemical-Biological Interactions and on study sections and advisory boards for the American Cancer Society. He was chair of the Safety Committee for the university’s oncology department for more than 20 years.

He is survived by his wife of 66 years, Mary Jean, and four children, seven grandchildren and five great-grandchildren.
