Harold Arthur Prichard was an English philosopher. He was born in London in 1871, the eldest child of Walter Stennett Prichard and his wife Lucy. Harold Prichard was a scholar at Clifton College from where he won a scholarship to New College, Oxford, to study mathematics. But after taking first-class honours in mathematical moderations in 1891, he studied Greats, taking first-class honours in 1894. He also played tennis for Oxford against Cambridge. On leaving Oxford, he spent a brief period working for a firm of solicitors in London before returning to Oxford, where he spent the rest of his life, first as a Fellow of Hertford College and then of Trinity College. He took early retirement from Trinity in 1924 on grounds of ill health, but recovered and was elected White's Professor of Moral Philosophy in 1928 and became a fellow of Corpus Christi College. He retired in 1937.
