"He was really community-minded," his son said.
"It started with him on the sidelines watching practices and games" when his children played. "And because he was so available, he kind of got roped in."
Even after his children were no longer players, his son said, "he really enjoyed the camaraderie of it" as well as "seeing progress being made" by other youngsters.
Mr. Mattei's name is inscribed on the Springfield Volunteer Memorial Wall, his son said.
Born in Nanticoke, Pa., Mr. Mattei graduated from South Philadelphia High School in 1948 and, his son said, worked under enemy fire as an Army combat engineer in Korea during his 1951-53 service.
Mr. Mattei served with the Philadelphia Fire Department from 1954 to 1959, rising to acting lieutenant with Engine Company 10.
Mr. Mattei's work with the Springfield Youth Club - football for boys, cheerleading for girls - began in the late 1970s and continued into the early 1990s, with youngsters ages 6 to 14, his son said.
At times, he was the club's coach, president, and director, earning its Spartan Award.
From 1984 to '86, he was commissioner of the Bert Bell Football Conference, which his son described as the NFL for Delaware County youngsters.
From the early 1980s to the early 1990s, he was a coach with the Springfield Athletic Association and was at times a member of its leadership.
After his coaching career, Mr. Mattei was a member of the Springfield Township Board of Parks and Recreation for five years in the 1990s.
In addition to being a Republican committeeman and judge of elections from the 1980s into the 2000s, he was chairman of the Springfield Township Zoning Board from the 1990s into the 2000s.
After his retirement and until he moved to Foxfield in 2006, his son said, Mr. Mattei was manager of the Springfield Country Club Pool.
In addition to his son, Mr. Mattei is survived by Ann, his wife of 53 years; son Samuel A.; daughter Dina Cavanaugh; four grandchildren; and two great-grandchildren.
