Suzanne Hecht was born in Paris to Albert Hecht (born in Brussels on 2 July 1842 and died in Paris on 21 August 1889), one of the greatest and most important Impressionist collectors, and Mathilde Oulman (born in Versailles on 8 July 1849 and died in Paris in 1937).
[2] Her father Albert had his friend Édouard Manet make three portraits of his daughter, dated 1882.
[3][4] With her husband Emmanuel Pontremoli, she began collecting the works of the most influential artists of the time, including John Constable, Eugène Delacroix, Édouard Manet, Claude Monet and Jean-Baptiste Camille Corot, some of which she inherited from her father.
[5] When Emmanuel Pontremoli died in 1956, he left his entire art collection to his daughter Mathilde, who was married to Jean Trenel (grandson of Rabbi Leon Trenel), who was deported to the Auschwitz death camp where he was murdered on 23 March 1943.
[6] Following the death of his daughter Therese in 1987, some paintings were given to the Louvre Museum in Paris.
