Seán Haldane can hold three passports: British (he was born in Sussex, in 1943), Irish (through his father, and he grew up mainly in Northern Ireland), and Canadian (through a long period of residence, 1967-94, in Québec, Prince Edward Island and British Columbia). By ancestry he is something of a human compass: a quarter each English, German, Scottish and Irish.

He was educated at the Royal Belfast Academical Institution, University College, Oxford (B.A., First Class Hons. in English) and Saybrook Institute, San Francisco ( Psychology). When he first found himself writing poetry he resolved never to make a living from it or by teaching it, and that any incidental earnings from poems would go towards publishing poetry by himself and others. He has worked as a lecturer, part time farmer, small press publisher, psychotherapist, consultant clinical neuropsychologist in the NHS and Canadian health services, and as an expert witness in criminal and civil cases.

He now lives in London and in Canada. In 2013 he founded Rún Press Ltd (Ireland), now Rune Press Ltd (UK) where he is co-publisher. He writes essays and reviews on poetry for various literary magazines and periodicals. He is working on a series of historical crime novels, the first two, The Devil’s Making (2013) and An Evil Tale I Heard (2022), are available through Rune Press and Guernica Editions and distributed by Gazelle Book Services. Sean is a member of the Crime Writers of Canada and the Crime Writers Association of Great Britain.
