Portrait of Dr. Gachet 68×57 cm 1890 Held at the Musée d'Orsay, Paris. This was Van Gogh's final portrait. In May 1890, he came to the town of Auvers-sur-Oise near Paris for recuperation under his brother's arrangements. He received regular psychological and physical counseling and care from Dr. Gachet, a homeopathic physician, and established a good relationship with the doctor's family. Encouraged by the doctor, he astonishingly completed 75 works in this small town (Clearly, when Van Gogh suffered nervous attacks and extreme physical and mental pain, this intense explosive power was directly manifested on the canvas, as evidenced by his late works). Many paintings featured Dr. Gachet's family and garden; this portrait is one of the most brilliant among them.

Dr. Gachet was an amateur painter who enjoyed literature and art collection, and had close friendships with artist friends such as Cézanne and Pissarro. Revering artists, he made Van Gogh feel completely at home, a fact proven by this portrait. Here, Dr. Gachet is shown well-dressed and wearing a hat, his thoughtful cheek resting against his tightly clenched fist, while the other hand holds a bouquet of flowers placed on the table. Against the contrasting color planes of blue-yellow and red-green, the portrait presents a harmonious and perfect balance, embodying an extraordinary modern form and emotion. Van Gogh wrote: "What I am passionate about is modern portraits (...) through the exploration of color."
