Thérèse Schwartze was a Dutch portrait painter.
Thérèse Schwartze was born on 20 December 1851 in Amsterdam in the Netherlands. She was the daughter of the painter Johan Georg Schwartze, who grew up in Philadelphia and trained in Düsseldorf.
Schwartze received her first training from her father, before studying for a year at the Rijksacademie van Beeldende Kunsten. She then travelled to Munich and studied under Gabriel Max and Franz von Lenbach. In 1879 she went to Paris to continue her studies under Jean-Jacques Henner. When she returned to Amsterdam she became a member of Arti et Amicitiae. Schwartze exhibited her work at the Palace of Fine Arts at the 1893 World's Columbian Exposition in Chicago, Illinois.
On 22 July 1918 her husband, Anton van Duyl, died. As Schwartze was in bad health at that time (and tried to hide this), the death of her husband was a blow that she could not overcome easily. She died in Amsterdam on 23 December 1918 from a sudden illness.
Schwartze was buried at Zorgvlied cemetery in Amsterdam. Later she was reburied at the Nieuwe Ooster cemetery in Amsterdam, where her sister created a memorial to her, modelled after her death mask, which is now considered a rijksmonument.
