Stumbling stones, originally ‘Stolpersteine’, are an initiative of the German artist Gunter Demnig. They are cube-shaped concrete stones with a brass top plate, with the text engraved on them. The stones are placed on the sidewalk in front of the houses from which the Jews were expelled and murdered. There are now more than 70,000 stumbling blocks in Europe.
Also in Heemstede, 2 stumbling stones have been placed in memory of Mrs Johanne Hedwig van Straaten and her sister Marie Mathilde van Straaten. Both died in German concentration camps. The granddaughter of Mrs Johanna van Straaten has taken the initiative for this. Her grandmother had a bookshop at number 91 Binnenweg from 1937 until the first years of the Second World War. That’s where the stumbling stones are placed.
