Ernest Dowson (1867-1900) was born in Kent in England, educated at Oxford though he left without taking a degree. He joined the Rhymer's club and contributed poems to The Yellow Book and The Savoy. In 1891 he met Adelaide Foltinowicz, a restaurateur's daughter, then aged 12 and she became a symbol of love and innocence for some of his verse. He nicknamed her Cynara (LINK) and he courted her for 2 years. When she came of age she married a waiter who worked in her father's restaurant. His parents committed suicide within a few months of each other in 1895 and afterwards he wandered aimlessly between England, France and Ireland. He was a friend of W B Yeats, who described him as 'timid, silent and a little melancholy'. He died an alcoholic, of tuberculosis, in 1900 at the age of 33.
