He was a member of the Nazi Party from 1933.[3] He benefitted from the Nazi policy of aryanisation, buying the Alexander Haus for a quarter of its value, after its owners, the Alexander family, had fled the country.[3] After the Second World War, his application for denazification was rejected, and he was barred from running his business until 1951.[3] His life is described in The House by the Lake (2015) by Thomas Harding, a non-fiction book about the Alexander House and the families who lived there.[4]
