Marguerite Gachet, daughter of Dr. Paul Gachet (shown here later in life) was the subject of a number of works by Vincent van Gogh while he was under the care of her father in Auvers-sur-Oise.
There has been a great deal of speculation that Vincent and Marguerite may have had an affair, but there is no evidence to support this. We can only surmise what Marguerite may have thought of this troubled Dutch painter, or what Vincent, in turn, thought of her.
