Born in May 1923 in Normanton, Derby, Harrison left school at 14 to train to be a decorator. During World War Two he served with the Royal Engineers, serving as an Army training officer based in England.
After playing non-league football for Derby Corinthians, Harrison signed for Derby County at the age of 16. He signed amateur forms in 1941 and turned professional in 1944, whilst he was also serving in the Army. During the war he guested for Sheffield United, Notts County, Charlton Athletic and Hartlepools United. He scored 52 goals in 254 league appearances for Derby, and 59 goals in 281 games in all competitions. Whilst with Derby, Harrison won the FA Cup in 1946. As of September 2018 he was also the oldest living FA Cup winner.
He left Derby to play for Boston United. He joined Long Eaton United as a player in 1957, becoming player-manager in February 1958, remaining in that position until May 1962. He later also managed Wilmorton & Alvaston and Alfreton Town.
After retiring as a player, Harrison worked for Derby City Council's Youth Service, and set up a youth centre and football club.
Harrison and his wife celebrated their 70th wedding anniversary in March 2015. The couple had two children (including a son who died from leukemia at the age of 7), two granddaughters, and, as of March 2015, one great-grandson. In September 2018 it was proposed by the local council that he would be awarded the Freedom of the City of Derby.
