Paul-Ferdinand Gachet was a French physician most famous for treating the painter Vincent van Gogh during his last weeks in Auvers-sur-Oise. Gachet was a great supporter of artists and the Impressionist movement. He was an amateur painter, signing his works "Paul van Ryssel", referring to his birthplace: Rijsel is the Dutch name of Lille.

Vincent Willem van Gogh was a Dutch Post-Impressionist painter who is among the most famous and influential figures in the history of Western art. In just over a decade, he created approximately 2100 artworks, including around 860 oil paintings, most of them in the last two years of his life. His oeuvre includes landscapes, still lifes, portraits, and self-portraits, most of which are characterized by bold colors and dramatic brushwork that contributed to the rise of expressionism in modern art. Van Gogh's work was beginning to gain critical attention before he died at age 37, by what was suspected at the time to be a suicide. During his lifetime, only one of Van Gogh's paintings, The Red Vineyard, was sold.
