The Schwarzschild family is an old established Frankfurt Jewish family. It is a branch of the older Wohl family, and took its name from one of its homes, the Schwarzes Schild. Initially the family worked particularly as butchers. It had many branches in the Judengasse, and it is striking how its members over the years took up very different occupations. Some of them, for example, had prominent functions in the Jewish community as community notaries, rabbis and dayanim, or worked as silk merchants, money lenders or cloth merchants. The historian Alexander Dietz mentions particularly Isaak Schwarzschild, who died in 1672 and whose gravestone praised him as "the wise elder, the scholar learned in all branches of Jewish literature, and who even when burdened by suffering in his ninetieth year never strayed from the Lord's teachings".
