Portrait of Dr. Gachet is one of the most revered paintings by the Dutch artist Vincent van Gogh. It depicts Dr. Paul Gachet, a homeopathic doctor and artist with whom van Gogh resided following a spell in an asylum at Saint-Rémy-de-Provence. Gachet took care of Van Gogh during the final months of his life. There are two authenticated versions of the portrait, both painted in June 1890 at Auvers-sur-Oise. Both show Gachet sitting at a table and leaning his head on his right arm, but they are easily differentiated in color and style. There is also an etching. The first version was acquired by the Städel in Frankfurt in 1911 and subsequently confiscated and sold by Hermann Göring. In May 1990, it was sold at auction for $82.5 million ($ million today) to Ryoei Saito, making it the world's most expensive painting at that time. It then disappeared from public view and the Städel was unable to locate it in 2019. The second version was owned by Gachet and was bequeathed to France by his heirs. Despite arguments over its authenticity, it now hangs in the Musée d'Orsay, in Paris. Background In late 1888, Van Gogh began to experience a mental breakdown, cutting off part of his ear. He stayed in hospital for a month, but was not fully healed and in April 1889 he checked himself into an asylum at Saint-Rémy-de-Provence, where he remained for a year. Released in 1890, Van Gogh's brother Theo searched for a home for the artist. Upon the recommendation of Camille Pissarro, a former patient of the doctor who told Theo of Gachet's interests in working with artists, Theo sent Vincent to Gachet's second home in Auvers. Vincent van Gogh's first impression of Gachet was unfavorable. Writing to Theo he remarked: "I think that we must not count on Dr. Gachet at all. First of all, he is sicker than I am, I think, or shall we say just as much, so that's that. Now when one blind man leads another blind man, don't they both fall into the ditch?" However, in a letter dated two days later to their sister Wilhelmina, he relayed, "I have found a true friend in Dr. Gachet, something like another brother, so much do we resemble each other physically and also mentally." Van Gogh had a very prolific spell during his stay with Gachet, producing more than seventy
