In 2011, her family presented her collection of exercise books, water colour albums, photographs, as well as samples of her work to the Textile Research Centre, Leiden (The Netherlands). This collection gives an unique look at the teaching of needlework in The Netherlands at the beginning of the twentieth century.
Part of the exhibition What is Embroidery? (TRC, 2013-2014), was dedicated to Henriëtte Slavekoorde-Braunstahl.
Her daughter, Sophia Margaretha Slavekoorde (born in 1915 in Voorburg), made a Feestrok to celebrate the liberation of The Netherlands from Nazi-Germany (1945). The Feestrok is now in the TRC collection (TRC 2011.0001a). Her photograph is also housed in the TRC collection (TRC 2011.0001c).
