He was awarded a President's Medal for his service to the university in 1998, and he received an honorary degree from the University of Massachusetts in 2005. He was also awarded a prize from the U.S. Particle Accelerator School in 1998 for his research.
Dr. Gluckstern served on, and in some cases chaired, a number of panels and committees, including the Maryland/D.C. selection committee for Rhodes scholars and the U.S. Department of Energy's High Energy Physics Advisory Panel.
His passion for teaching extended beyond the university setting, his family said.
"He would never give you the answer," said Steven Gluckstern, whose mother, Norma Block Packard, was separated from Dr. Gluckstern in 1981. He recalled that his father "never missed an opportunity to teach."
He and his siblings realized early on that their father "was someone who thought differently," arriving at answers much more quickly than others - but always willing, and wanting, to explain how to get to those answers.
"It was actually quite wonderful growing up in a house with a man who was that insightful," his son said. "He had the ability to take very complicated things and break them down into bite sizes."
Beyond his academic interests, Dr. Gluckstern played the clarinet and saxophone and loved doing crossword puzzles, his wife said.
A memorial service is scheduled for 1 p.m. Jan. 25 at the university's Clarice Smith Performing Arts Center, in Dekelboum Concert Hall.
Dr. Gluckstern is also survived by two daughters, Barbara Joy Greenspan of Teaneck, N.J., and Amie Yabroff of Washington; a brother, Allan Gluckstern of Boca Raton, Fla.; and six grandchildren.
He was predeceased by a daughter, Joanne, who died in 1955.
