William Joseph Simpson (12 December 1929 – 27 January 2017[2]) was a Northern Ireland international footballer, who played for Linfield, Rangers, Stirling Albion, Partick Thistle and Oxford United.
He left Ibrox in 1959 and spent the last couple of years of his career with Stirling Albion, Partick Thistle and (then non-league) Oxford United.
He was selected in Northern Ireland's squad for the 1958 FIFA World Cup in Sweden but a late injury ensured he did not play at all during the finals.
In April 2015, the feature-length documentary Spirit of '58 was screened as part of the Belfast Film Festival.
It featured Billy Simpson prominently alongside the other surviving players (Billy Bingham, Peter McParland, Jimmy McIlroy and Harry Gregg) as it told the story of Northern Ireland's journey throughout the 1950s under the managership of Peter Doherty, culminating in the 1958 World Cup.
