On 4 August 1944, Kleiman was arrested with
Victor Kugler during the
Gestapo raid that arrested the
Frank family and four other concealed
Jews in the premises on the Prinsengracht. After interrogation at Gestapo headquarters, he and Kugler were transferred to a prison on the Amstelveenseweg for Jews and
political prisoners awaiting deportation. Kleiman was imprisoned in the Amersfoort labour camp before he was released by special dispensation of the
Red Cross because of his ill health. In all, he was a prisoner of the Nazis for about six weeks. After the publication of Anne Frank's diary, which detailed her two years in hiding, Kleiman regularly took journalists and visitors around the former hiding place, which had been vacated in the early 1950s. He became very involved in the establishment of the Anne Frank Stichting (
Anne Frank Foundation) on 3 May 1957 but did not live to see the building open as a museum in May 1960. == Death and legacy ==
