Mr Hemingway was one of 36 Irish pilots who fought in the Battle of Britain, including Wing Commander Brendan ‘Paddy’ Finucane, who was one of the RAF’s most successful fighter aces in the war, and Victor Beamish, a scion of the brewing industry. Both were killed in the war.
In 2019, Mr Hemingway gave an interview to The Irish Times on the occasion of his 100th birthday. He told military historian Joseph Quinn: “I can’t say don’t drink. I can’t say don’t fool about with people. I can’t say don’t fly aeroplanes. I can’t say don’t shoot and get shot at – I’ve done everything, and I’m an Irishman. The only advice I can give to people is be Irish!”
Mr Hemingway’s wife Bridget died in 1998. They had three children.
He lived with daughter in Canada for many years before returning to Ireland in 2011. Mr Hemingway spent his last years in the Trinity Care Foxrock Nursing Home.
