Born Charles Leonard Augustus Parsons in Filey, Yorkshire, England, he was the illegitimate son of two middle class travelling entertainers. His father Charles Parsons had the stage name Jimmy Lynton while his mother Mary Augusta Ridgway Bridson was known as Celia Ridgway and was a daughter of Augustus William Bridson and Maria Emily Montford. The couple met on tour in England. Their hectic lifestyles prompted them to give up baby Leo, who was fostered out to a working class couple, a Glasgowshipyard worker named James Blair and his wife Mary, taking their surname. On 2 June 1927 his biological parents married and tried to reclaim him, but Mary Blair refused to return him and later prevented him from contacting his biological parents. Blair grew up in a tenement in Golspie Street, Govan, Glasgow, and attended Govan High School. When he left school he worked as a copy boy on the Communist Party newspaper The Daily Worker and was Secretary of the Scottish Young Communist League from 1938 to 1941. He studied law at the University of Edinburgh, becoming a barrister and later, a university law lecturer.
Marriage and children
Blair married Hazel Elizabeth Rosaleen Corscadden from a Protestant family in Donegal, Ireland. They were married by the future Moderator, Rev William Roy Sanderson, at Barony Church in Glasgow. They had two sons, both of whom attended Fettes College, and a daughter. Their first son, Sir William Blair, a banking and finance law specialist, became a High Court judge. Their second son, Anthony Charles Lynton Blair, was born in 1953 and also became a barrister before becoming a politician and Prime Minister of the United Kingdom. At the end of 1954 the family moved to Adelaide, Australia, for 3½ years, where Blair lectured in law at the University of Adelaide. Blair and his family later returned to England, living in Durham, where Blair lectured in Law at Durham University Law School. He was a member of St Cuthbert's Society, one of the university's collegiate bodies. Despite having been a communist in his youth, Leo became active in the Conservative Party. He had ambitions to stand for Parliament in Durham, hoping to become a candidate in the 1964 general election, which were thwarted when he suffered a stroke in 1963 at the age of 40. Following Blair's stroke, he had to rely heavily on his wife Hazel to look after him.
Later life
Blair joined the Labour Party when his son became Leader in 1994, citing pride at his son's achievements, his dissatisfaction with the Conservatives under John Major and his objection to railway privatisation. He had previously been "a huge supporter" of Prime Minister Margaret Thatcher. Blair's first wife, Hazel, died on 28 June 1975 of thyroid cancer. He remarried and lived in Shrewsbury, Shropshire, with his second wife, Olwen, until his death. Cherie and Tony Blair named their youngest son Leo after him. Blair was a "militant atheist" according to his son Tony. Blair died at the age of 89 on 16 November 2012.
Academic work
Blair's book The Commonwealth Public Service was described by the journal Canadian Public Administration as "an excellent primer on the Australian Federal Public Service".
