Born in Coatbridge, near Glasgow, inside forward Tommy Gallogley began his career with local side Bedlay Juniors. In 1913 he was spotted by Plymouth Argyle manager Bob Jack and moved south to join Argyle, making his debut in November 1913 at Watford. He spent the next six seasons at Plymouth, playing either side of the War, and in total scoring 22 goals in 136 appearances for The Pilgrims, of which 9 goals in 62 were Football League games. During the war he returned north of the border and played as a guest for Royal Albert, Motherwell, Airdrieonians, Albion Rovers and Vale of Leven, before returning to Home Park and resuming his position in the first team as Argyle entered the Football League. An inside-forward who could play on both the right and left side, Gallogley was described by the Plymouth club handbook as being a player who “has fine command over the ball and passes judiciously. He is also dashing and strong and should develop into a tip-topper”. After the 1922-23 campaign, with his opportunities becoming more limited, he moved to Exeter City, where he played for a single season, scoring once in 28 games. He ended his career back in his native Scotland with spells at Queen of the South and Albion Rovers.
