"It was Pissarro's sympathetic attitude to all sincere efforts which prompted Theo van Gogh to ask him... whether he could help his brother. After his first attack, Vincent had remained for one year at the Saint-Rémy Asylum... where he had been able to work between repeated spells of madness... [He] had asked Theo to find him a place near Paris... At Theo's request Pissarro was ready to take Vincent into his house... but Madame Pissarro was afraid [for] her children. Pissarro thereupon recommended his old friend, Dr. Gachet at Auvers, who declared himself willing to take care of Vincent. The latter came to Auvers in May 1890; he killed himself there in July of the same year... After the suicide... Theo van Gogh fell seriously ill; he was taken to Holland and died in January 1891. He was replaced at the gallery... M. Boussod, the owner, complained that Theo... had "accumulated appalling things by modern painters which had brought the firm to discredit. Indeed, Theo had left a stock of works by Degas, Gauguin, Pissarro, Guillaumin, Redon, Lautrec, Monet and others. According to M. Boussod only Monet's canvases were saleable..."
