Velleman was born in
Groningen in the Netherlands and later moved to
Amsterdam. He wrote a booklet of simple magic tricks that was published in 1925. His precise politics are not known, but he supported workers' rights, and gave free magic performances to striking workers during the 1920s. Besides paid work in
variety shows, he often performed for charity, including at
almshouses. His family was sent through the
Westerbork transit camp before arriving at the
Sobibor extermination camp. His daughter Aaltje, who had
Down syndrome, was murdered at Sobibor in May 1943. Velleman and Anna both died in 1943 at Sobibor. His son Jacques survived the war. == Wilmink's Poem ==
