Tonkin was born in North London[3] and studied English and French literature at Trinity College, Cambridge University,[4] as both an entrance scholar and a senior scholar.[5] He worked as a lecturer in literature, before exchanging academia for journalism, initially as a staff writer and features editor on the magazine Community Care.[3] He then worked at the New Statesman as social affairs editor and on the books desk, before going on to The Independent, where he was literary editor from 1996 to 2013 and Senior Writer and Art Critic until 2016.[6][5][7]
In 2001, Tonkin re-founded the Independent Foreign Fiction Prize – established in 1990 to honour author and translator equally[8] – which he co-judged until it was merged with the Man Booker International Prize in 2015.[6] He chaired the judging panel of the Man Booker in 2016, and other prizes for which he has served as a judge include the OCM Bocas Prize for Caribbean Literature,[9] the Wasafiri New Writing Prize,[10] the Whitbread biography award, the Commonwealth Writers Prize, the David Cohen Prize (2007) and the Prix Cévennes.[11][5]
In addition to his work for The Independent, Tonkin has written for The Observer, Financial Times, The Guardian, The Economist, The Spectator, New Scientist and Newsweek, among other publications, is a contributor to arts and current-affairs programmes on BBC Radio, and has been a commentator on literary issues internationally, as well as an invited participant and speaker at festivals and educational institutions worldwide.[5]
He is the author of the book The 100 Best Novels in Translation (Galileo, 2018), a "cross-border guide to fiction",[12][13] about which Ian McEwan said: "This is a brilliant and extremely useful guide, approachable on every level. Boyd Tonkin opens up infinite worlds of the imagination."[14]
In November 2020, Tonkin was awarded the Benson Medal[15] and was elected an Honorary Fellow of the Royal Society of Literature (RSL).[16] Lisa Appignanesi, chair of the RSL, described Tonkin as "one of the key people in the shaping of literature in the UK."[2]
