In Baltimore, he played for many years at the old Love's Restaurant and Cocktail Lounge at Charles and 25th streets.
In 1964, Mr. Anders began his 47-year career at McDonogh School, where he rose to head the music department.
"By the time he retired in 2011, Marsh had directed every single musical group on campus, given countless private lessons, and run the entire Music Department," said the McDonogh Magazine profile.
Noreen Lidston, who was head of the lower school, said in the article that "Mr. Anders has meant the world to three generations of children. With complete joy and unending kindness, he has taught pre-firsters how to play the kazoo, trained students to become concert pianists, and everything in between."
"He had a long, long influence here," recalled Mr. Olsen, who said the school was putting together a George Gershwin medley for Mr. Anders' memorial service. "Marsh just loved Gershwin," he said.
One of Mr. Anders' longtime private piano students was Paige A. Unitas, who lives in Lutherville.
"He was a great teacher and very patient. For me, when I was learning to play piano, the lesson books could be very boring, but he would say to me, 'Pick out something you want to play,' and he'd help me learn it," said Ms. Unitas. "He wanted you to enjoy playing the piano."
From 2001 until last year, Mr. Anders was a member of Sentimental Journey Orchestra, a 17-piece ensemble that practiced weekly and played at area nursing homes, retirement communities and hospitals.
The longtime Towson resident enjoyed fishing and watching stock car races and "The Charlie Rose Show," family members said. He was a record collector and also maintained a lively interest in current events and politics.
A memorial service for Mr. Anders will be held at 11:30 a.m. Saturday in the chapel at McDonogh, 8600 McDonogh Road.
In addition to his daughter and brother, Mr. Anders is survived by two sons, Paul Anders of Ellicott City and Alan L. Anders of New York City; a sister, Lee Woolford of White Hall; four grandchildren; and three great-grandchildren. His wife of 44 years died in 1991.
