Mr. Panitz had served as a trustee of the Baltimore Symphony Orchestra, Citizens Planning and Housing Authority, Home Builders Association of Maryland, Enterprise Development Co., and Westview Savings & Loan.
He was a member of the Hopkins Club and the Center Club.
"But his favorite club was the Petit Louis restaurant in Roland Park," said his wife.
A drummer, Mr. Panitz was a founder of the Chamber Jazz Society. He was also an avid student of history and a world traveler.
In 1985, he and his wife built a home on Martha's Vineyard, where they lived four months of the year until they sold it in 2006.
A memorial service will be held at 11 a.m. Sept. 9 at the Evergreen Museum and Library, 4545 N. Charles St.
In addition to his wife, he is survived by a son, Thomas Panitz of New York City; three daughters, Susan Fillion of Ruxton, Amy Panitz of Manchester, Vt., and Polly Panitz of McLean, Va.; a stepson, Jonathan Watts of Kamakura, Japan; two stepdaughters, Anne Watts of Cambridge and Caroline Watts of Philadelphia; 10 grandchildren; and five step-grandchildren.
An earlier version misstated Shale D. Stiller's position with the Harry and Jeanette Weinberg Foundation. He is a former president and trustee, and was succeeded in 2010 by Rachel Garbow Monroe. The Baltimore Sun regrets the error.
