Michael Innes is the pseudonym of John Innes Mackintosh Stewart, who was born in Edinburgh in 1906. His father was Director of Education and as was fitting the young Stewart attended Edinburgh Academy before going up to Oriel, Oxford where he obtained a first class degree in English.
After a short interlude travelling with AJP Taylor in Austria, he embarked on an edition of Florio's translation of Montaigne's Essays and also took up a post teaching English at Leeds University.
By 1935 he was married, Professor of English at the University of Adelaide in Australia, and had completed his first detective novel, Death at the President's Lodging. This was an immediate success and part of a long running series centred on his character Inspector Appleby. A second novel, Hamlet Revenge, soon followed and overall he managed over fifty under the Innes banner during his career.
After returning to the UK in 1946 he took up a post with Queen's University, Belfast before finally settling as Tutor in English at Christ Church, Oxford. His writing continued and he published a series of novels under his own name, along with short stories and some major academic contributions, including a major section on modern writers for the Oxford History of English Literature.
Whilst not wanting to leave his beloved Oxford permanently, he managed to fit in to his busy schedule a visiting Professorship at the University of Washington and was also honoured by other Universities in the UK.
His wife Margaret, whom he had met and married whilst at Leeds in 1932, had practised medicine in Australia and later in Oxford, died in 1979. They had five children, one of whom (Angus) is also a writer. Stewart himself died in November 1994 in a nursing home in Surrey.
