Jimmy McGrory

James Edward McGrory (26 April 1904 – 20 October 1982) was a Scottish footballer who played for Celtic and Clydebank as a forward and then went on to manage Kilmarnock before returning to Celtic as manager after the end of the Second World War.
He is the all-time leading goalscorer in top-flight British football with a total of 550 goals in competitive first-team games at club and international level. McGrory is a legendary figure within Celtic’s history; he is their top scorer of all time with 522 goals, and holds their record for the most goals in a season, with 57 League and Scottish Cup goals from 39 games in season 1926–27. He has also notched up a British top-flight record of 55 hat-tricks, 48 coming in League games and 7 from Scottish Cup ties. It could be argued he in fact scored 56, as he hit 8 goals in a Scottish League game against Dunfermline in 1928, also a British top-flight record.
He was at Celtic for 15 years between 1922 and 1937, although he did spend the majority of the 1923–24 season on loan at fellow Division One side Clydebank. After a spell managing Kilmarnock from December 1937 to July 1945, he became Celtic manager, where he remained for just under 20 years, until March 1965 when he was succeeded by Jock Stein.
Even although he was only 5 ft 6ins, he was renowned for his prowess and ability from headers. His trademark was an almost horizontal, bullet header, which he performed and scored regularly from and which earned him his nicknames, of the “Human Torpedo” and the “Mermaid”.[1]
