Montessori Lyceum Amsterdam in Amsterdam-Zuid installed Stolpersteine at its entrance for former pupils Gideon Boissevain, Lodewijk Gompertz and Hans Kalker, who were murdered during the Second World War. Boissevain was shot in the dunes at Overveen aged 22, Gompertz died at Bergen-Belsen aged 16, and Kalker was murdered at Auschwitz aged 24.

Pupils spent six months researching the former pupils, including through old school reports and records of their deportations. The three stones are the first in a long-term project in which the school plans to install stones for 35 murdered former pupils and teachers, adding new ones each year.
