Michael Langdon (12 November 1920 – 12 March 1991) was a British bass opera singer. Langdon was born in Wolverhampton. He had six half brothers and sisters, the youngest, Maud being 19 years his senior. His father, Harry was sixty when his youngest son was born (birth name Frank Birtles) and by all accounts a very strong personality. He was blind and after he retired from business, his young son spent much time with him, reading to him, sharing walks and conversation and learning to play the piano. Harry died when Frank was ten. Frank promptly failed the 11 plus, to his teacher's amazement. He excelled at the less academic school he attended. He disliked school and was pleased to leave.
