One of the trades always practised by Jews was that of tailor, because Jewish law contains special rules about dress. For example, vegetable and animal fabrics such as cotton and wool may not be mixed. In earlier times clothes were not massproduced as they are today but were always tailormade. Many women earned their living as seamstresses. At the end of the 17th century a widow living at the Schule worked as a seamstress. There were also several specialists among the Jewish tailors. Death records at the end of the 17th century refer to Avrom the bonnetmaker and Mosche the doubletailor. Many tailors came from elsewhere, most from Poland. In contrast to other Jewish occupations, such as cobbler, shames, or goldsmith, tailors did not register their trade as their family name.
