A memorial plaque listing the names of staff members who did not survive the war has been affixed in the former residence of the director of the Stoomweverij Nijverheid (part of the Van Gelderen family business) at 2 Nijverheidstraat in Enschede. Eight of those listed were Jews, including Salomon Frankenhuis.
The memorial plaque can be found on the website of the Nationaal Comité 4 en 5 mei.
