This man will either go insane or leave us all far behind, prophesied the great Impressionist Camille Pissarro. The man was Vincent van Gogh (1853-1890), a vicars son born at Groot-Zundert near Breda in Holland, who at that time was struggling to find buyers for his paintings. Van Gogh did indeed go at least to the brink of insanity. And he has long been recognised as one of the greatest modern artists. Van Gogh, who followed a variety of professions before becoming an artist, was a solitary, despairing and self-destructive man his whole life long. His truest friend was his brother Theo, who supported him unstintingly throughout and followed him to the grave just six months later.
