Wilde's parents were successful Anglo-Irish Dublin intellectuals. Their son became fluent in French and German early in life. At university, Wilde read Greats; he proved himself to be an outstanding classicist, first at Dublin, then at Oxford. He became known for his involvement in the rising philosophy of aestheticism, led by two of his tutors, Walter Pater and John Ruskin. After university, Wilde moved to London into fashionable cultural and social circles. As a spokesman for aestheticism, he tried his hand at various literary activities: he published a book of poems, lectured in the United States and Canada on the new "English Renaissance in Art", and then returned to London where he worked prolifically as a journalist. Known for his biting wit, flamboyant dress and glittering conversation, Wilde became one of the best-known personalities of his day.
