Menachem Shimoni, (formerly Emil Neumann) was born in Poland in 1927 to Orthodox Jewish parents. During his childhood, the family moved to Budapest. In 1944, after the German invasion, the family boarded the “Kastner train” that took them to Bergen-Belsen. While there, Menachem made a calendar from memory, for the Jewish year 5705 (1944-45). It included all festivals, special days, and the weekly Torah portion. It served many religious prisoners in the camp, who tried to remain observant.
