Henry "Harry" Haddock (28 July 1925 – 18 December 1998) was a Scottish footballer who spent almost his entire career with Clyde. He was also selected in the Scotland squad for the 1958 FIFA World Cup.
Haddock was born in Glasgow and as a left back joined Clyde in September 1949 and became a reliable fixture in the side over the following 13 seasons, latterly as captain. He enjoyed his fair share of ups and downs during this period: the Bully Wee were relegated in 1950-51, 1955-56 and 1960-61 although they enjoyed an instant return as Second Division champions on each occasion. Haddock also helped his side reach two Scottish Cup Finals, both of which were won. In 1954-55, Celtic were defeated 1-0 in a replay, while in 1957-58, Hibernian were defeated 1-0 at the first attempt.
Haddock's international career was somewhat less auspicious, as Scotland won only 1 of the 6 games he featured in. This included two heavy defeats by England, 7-2 in 1955 and 4-0 in 1958. Following the 7-2 defeat, Haddock was publicly praised by the great Sir Stanley Matthews for his refusal to resort to foul play. In 14 years as a senior and international footballer Haddock was never booked, sent off, or even admonished by any referee. The latter match would prove to be his final international appearance, as despite his selection in the 1958 World Cup squad, he did not feature in the finals in Sweden. In 1959 Haddock was voted Scottish Player of the Year at the age of 34. In addition to the 6 full internationals, Haddock was also selected to play in seven Scottish League XI matches. Haddock also played for a Glasgow Select XI on seven occasions, captaing the side on his last appearance.
Haddock died in Rutherglen, Glasgow in 1998. He is survived by his sons Robert and Gerard and daughter Josephine. His wife Helen died in 2011, and eldest daughter Helen-Marie died in 2004.
