Arnold Troostwijk (* 1941) was born in the Dutch city of Arnhem. When the persecution of Jews increased in 1942, his parents made plans to flee the Netherlands for Switzerland. However, this was a dangerous undertaking. They therefore decided to take only their two eldest children with them on this escape – traveling with a baby was too risky. Little Arnold was therefore hidden with the Doets family under the cover name Petertje van Schaik. His parents managed a spectacular escape with the other two children via Antwerp and Paris to Switzerland. After the war, Arnold finally met his mother and father again – whom he no longer recognized.
