Scott is born in Belfast on August 24, 1893. He plays for Linfield and Broadway United before Liverpool manager Tom Watson signs him on September 1, 1912, following a recommendation from Scott’s older brother Billy Scott. Liverpool only gets the opportunity to sign Scott when Everton decides that the 19-year-old is too young.
Scott is reported as signed by Crewe Alexandra in August 1913, presumably under some sort of loan arrangement. He succeeds Thomas Charles Allison as deputy for the first choice keeper, Arthur Box, and plays for them in the early part of the 1913-14 season.
During the early days of his career, Scott is understudy to Kenny Campbell and only appears occasionally. World War I interrupts his career for four years. He finally gets a chance of a run in the Liverpool goal at the end of the season. His goalkeeping position is set in stone when Campbell is allowed to leave in April 1920. He establishes himself as Liverpool’s number one. He is a major part of the back-to-back Championship winning teams of 1922 and 1923, missing just three games of the first title and none in the second.
Numerous stories about Scott exist in Liverpool folklore. One such story relates to a 1924 game, after Scott has just made a phenomenal save at Ewood Park against Blackburn Rovers. A man appearing from the crowd goes over to Scott and kisses him. He is part of one of the legendary rivalries of the day along with Everton’s Dixie Dean. The two of them are the main topic of discussion when the day of the Merseyside derby is approaching. Everton declares that Dean will score while Liverpool disagrees, saying Scott will not let a single shot past. A famous story, possibly apocryphal, associated with the two men is that of how they once encountered each other in Belfast city centre the day before an Ireland versus England game. Dean, famed for his remarkable heading ability, touches his hat and nods to Scott as they are about to pass. Scott responds by diving as if to try to save an imaginary header, much to the initial shock and then delight of the locals who witness it while a mildly shocked Dean smiles and quietly continues on his walk.
Towards the end of the decade, Scott loses his starting position to another Liverpool goalkeeper, Arthur Riley, but he never gives up the battle for the position of goalkeeper. However, at the beginning of the 1930s it becomes more and more difficult for Scott to get into the line-up. Eventually he asks if he can return to his homeland when his old team Belfast Celtic offers him a player-manager role in 1934. Liverpool consents. He plays the last of his 467 appearances at Chelsea on February 21, 1934, where Chelsea defeats Liverpool 2–0.
Upon Liverpool’s final home match of the season Scott heads to the director’s box to give his adoring fans a farewell speech. He plays his final game for the Belfast club in 1936 at the age of 42. In his time as manager of the Celtics, he wins ten Irish League titles, six Irish Cups, three City Cups, eight Gold Cups and five County Antrim Shields.
Scott dies in Belfast on May 16, 1959 and is buried in Belfast City Cemetery.
