Salo Muller (* 1936) is a Dutch physiotherapist, journalist, and publicist. Along with his parents, he was summoned by Nazi decree to the Hollandsche Schouwburg, a theater that served as a staging area for deportation to extermination camps in Eastern Europe. He was among several children who – with their parents’ permission – were spirited out of the building and hidden with non-Jewish families by the Dutch resistance. Salo’s parents were murdered in Auschwitz and a surviving aunt brought him back to Amsterdam after the war where she raised him. Muller’s school years were marked by major difficulties in adapting due to the traumatic experiences of hiding and he dropped out of school. Without completing formal education, Salo Muller began training as a remedial gymnast and masseur. In 1960, he officially became the physiotherapist of the Ajax Amsterdam Soccer Club and witnessed up close the team’s rise to its golden years. From there Muller focused on building his own practice, served as editor-in-chief of the professional journal Fysioscoop, and published several books about his experiences during the war years. The title of one – “Tot vanavond en lief zijn hoor” (See you tonight, and be good) – were the last words his mother said to him at the entrance of the kindergarten.
