A. M. Klein holds a central place in Canadian literature for two reasons. He was the first writer from an ethnic minority – that is, of neither French nor English background – to have made a genuine and lasting contribution to the multi-cultural fabric of Canadian literature. In addition, Klein was one of Canada’s leading modernist poets, and his account of the role of the poet in the mid-twentieth century, “Portrait of the Poet as Landscape”, is one of the most powerful and most frequently cited poems in Canadian literature. In fact, Klein’s career, with its great achievements and tragic conclusion, can best be seen as a working out of the tensions, unbearable at times, between his Jewishness and his modernity.
