Quinnipiac faculty members Jack Kaplan, 61, and Joachim Schnabel, 65, died last week in unrelated circumstances, according to separate announcements on MyQ.

Kaplan, a professor of mathematics, spent more than 28 years as part of the Quinnipiac faculty. He died at home on Thursday, according to the Weller Funeral Home in New Haven.

According to Mark Thompson, senior vice president for academic and student affairs, Kaplan was an active member of the Quinnipiac community, and “beloved by students and his faculty colleagues.”

Schnabel, an adjunct professor, taught classes in the School of Business and in the QU Seminar series before passing. On Oct. 4, Schnabel passed away at the Hospital of St. Raphael, according to the Iovanne Funeral Home in New Haven.

Born in Germany, Schnabel became a naturalized American citizen in 1962, and served in the U.S. Navy as a gunnery officer. He was later awarded the National Defense Service Medal, an honor for serving at a time when a national emergency was declared.
