Gene Duman, a band director who taught in Fairfax County public schools for more than five decades, died Sept. 4 at Reston Hospital Center. He was 76.

The cause was a blood infection, said his wife, Barbara Duman.

Mr. Duman joined the Fairfax school system in 1958 and taught over the years at Edison High School in Alexandria, Herndon High School, Kilmer Middle School in Vienna and Longfellow Middle School in Falls Church.

After retiring in 2005, he continued teaching in Fairfax elementary schools and as a substitute teacher, as well as at private schools including Green Hedges School in Vienna and Flint Hill School in Oakton.

Mr. Duman also worked part time at the Tower Records music store at Tysons Corner and gave tuba and euphonium lessons.

George Eugene Duman Jr. was born in Johnstown, Pa., and received a bachelor’s degree in music from the Peabody Institute in Baltimore in 1954. He was a Reston resident.

He belonged to several music education organizations and received honors that included the 1967 award for Fairfax County’s teacher of the year, his wife said.

Mr. Duman collected and repaired old radios and belonged to the Mid-Atlantic Antique Radio Club. He was volunteer docent at the National Capital Radio and Television Museum in Bowie.

Survivors include his wife of 55 years, Barbara Miller Duman of Reston; two sons, Eric Duman of Reston and Christopher Duman of Sterling; a sister, Marsha Hudson of Bel Air, Md.; and a granddaughter.
