In 2015 'Thérèse Schwartze, Painting for a living' was published about the artist who has several paintings in the collection of the Amsterdam Museum. The most striking is the group portrait of the Boissevain sisters that Schwartze painted in 1916 and that in many respects is a time document. On the occasion of the silver wedding of his eldest son, Charles Boissevain (1842-1927) commissioned the artist to paint his granddaughters, the eldest of whom was 19 and the youngest six years old. Charles Boissevain Jr. (1868-1940) and Maria Barbara Pijnappel (1870-1950) were the silver wedding couple. In addition to their six daughters they also had four sons. Father was ammonia manufacturer and active in municipal and provincial politics. In addition, he held various management positions, including in the Society for the Promotion of Art and in the Concertgebouw. He was befriended by conductor Willem Mengelberg, who lived in the Van Eeghenstraat, as did the Boissevain family. There was a lot of music in the Boissevain house, as the oldest daughter Helena sang, the among others the St. Matthew Passion, in the Toonkunstkoor, and she married Dick Meesman, who was a violinist and later a clarinetist in the Concertgebouw Orchestra. The mother of the house was a progressive woman, active as president of the Association for Women's Suffrage and of the Society for the Benefit of General. From 1919 to 1939 she was a member of the Provincial States of North Holland. Besides a good education, the daughters also had the example of a hard-working woman with strong opinions. Helena became a teacher at the Montessori school and her sister Maria Cornelia chose the new profession of x-ray assistant. With her husband, the surgeon Jan de Jong, she moved to Batavia in the thirties and from there emigrated to America, where she lived until her death. An appetite for travel was also a family trait perhaps inherited by their Irish grandmother Emily Héloïse MacDonnell (1841-1931) who married Charles Boissevain in 1867. Emily, the third daughter, was named after her and left for England at a young age where she married and founded a family. Catherine, also known as Teau, was born in 1905. Like her sisters she got a good education, and went into nursing. She married Carl Huisken who worked in securities trading; with their family they lived in het Gooi. Teau died in 2002 at the age of 97 as the last of the six sisters. Thanks to her mediation, the group portrait came in 1990 into the collection of the Amsterdam Museum. Els was nine years old when she posed together with her sisters; she opted for a career as a secretary. In 1938 she married Liko Krejcik from Petersburg. The war years were difficult, two of their children died young and shortly afterwards they went to Indonesia, but like her sister Maria they had to flee. They then opted for Australia where Els died in 2000. The youngest daughter Dieuke was the tenth and last in line of the Boissevain children. She studied law and started working at a law firm. In the war she married Carel Nienhuys. She gained fame as a journalist and writer of detective novels, which also appeared in translation abroad. Together the lives of the six sisters span a century. Not only their own lives and careers but also their family ties, circle of friends, children and grandchildren provide enough material for a historical novel in many parts. The war, their travels from continent to continent, their sporting, scientific and cultural performances, and not least their social involvement form a colorful 20th-century mosaic.
