Sir Isaiah Berlin, O. M., was born in Riga, Latvia, in 1909. He came to England in 1919 and was educated at St Paul's School and Corpus Christi College, Oxford.

His achievements as a historian and exponent of ideas earned him the Erasmus, Lippincott, and Agnelli Prizes, and his lifelong defence of civil liberties earned him the Jerusalem Prize. He died in 1997. Henry Hardy, a Fellow of Wolfson College, Oxford, is one of Isaiah Berlin's Literary Trustees. He has edited several other books by Berlin, and is currently preparing a selection of his letters for publication.
