Initially a half forward, Gallagher hailed from Rosebud.
In doing so he joined John Coleman and Ted Freyer as the only players to have kicked 12 goals or more in a game for Essendon.
He also booted three majors in the 1957 VFL Grand Final where he was his club's only multiple goal-kicker in a 61-point loss to Melbourne.
With his place in the side no longer assured in 1958, Gallagher opted to join New South Wales club Turvey Park as captain-coach.
