His sister Jo Garcia informed The Hamlet that David died last Sunday.
To all of his family and friends, as well as his partner Sally, we offer our deepest condolences from all at Dulwich Hamlet Football Club.
David, or 'Pressure Harry' as he was affectionately known by the Hamlet faithful, due to him continually exhorting the team to put 'pressure' on the opposition, first saw Dulwich play as a five year old boy, way back in 1954, taken along to a game at the old Champion Hill by Jo. He was also a local man, living in the flats across the road from the ground at the time.
David was a regular home and away, and regardless of how poor the Club may have played at times he was ALWAYS on the terraces, shouting encouragment. He was never happier than in recent seasons, seeing so many fans flocking to Champion Hill and singing their hearts out for the team.
Club Secretary Martin Eede said: "It's a great shock. I will miss him immmensely. In all my time at the Club David was one of those who would be there ready to help out at the ground, not being asked, but quietly volunteering to help, just because he loved Dulwich Hamlet."
Chairman Jack Payne also paid tribute: " He was one of our loyalist supporters, and always one of the first to be at the ground on a match day. It won't be the same without him."
Fellow supporter Mishi Morath continued: "I've been following Dulwich since I was a kid in the Seventies. Everyone knew 'Harry'. As a youngster I always remember his Dulwich Hamlet Union Jack in the back window of the supporters coach, and hanging behind the goal, long before we had the multitude of flags we have today!"
The funeral will be tomorrow at Golders Green Crematorium, Hoop Lane, NW11 7NL; in the East Chapel, with the service being at 1.30pm.
This is only five minutes walk from Golders Green underground station, on the Northern Line.
The family have requested no flowers, but any Dulwich Hamlet fans are welcome to attend.
