After earning a doctorate in 1942, he joined the chemistry faculty at Penn State, where he lived and worked for the next 40 years. He coauthored a textbook, Synthetic Organic Chemistry, in 1953. At Penn State, he served as assistant head of the Department of Chemistry, vice president of research, director of intercollege research programs and associate dean of the graduate school.

Harry David Zook
After his retirement from Penn State, Harry moved to Winter Park, Fla., where he devoted himself full time to his interest in genealogy. He and his wife, Margaret, traveled throughout the U.S. and Europe, visiting courthouses, libraries, and cemeteries. Harry's interest was tracing the descendants of 18th century Amish Zook immigrants to America and investigating their origins in Europe. His first "Zug/Zuck/Zouck/Zook Genealogy" was published in 1983, but he continued his research for another 25 years, publishing a revised and updated second edition in 2009, at the age of 93.

He is survived by: his children, Stephen M. Zook, of State College, and Terri Zook Johnson, of Madison, Wis.; his grandchildren, Michael Zook, Daniel Zook, Amy Zook Castor, Jyothi Froemming and Naveen Froemming; and his great-grandchildren, Mitchell and Oleg Zook. He is also survived by his cousin, Grace Weiler, and long-time friends Louise Warner, Doug Zook and Shelby Woody.
