Together with other Jewish bibliophiles, the law student Herrmann Meyer founded the Soncino Society of Friends of the Jewish Book in 1924 in order to cultivate the exchange of information about Jewish books and, according to the statutes, to publish "rare texts and valuable prints. Soon the society had over 500 members from Germany and abroad. The most ambitious project was the development of a new Hebrew typeface. At the beginning of 1933, the printing of the Torah was finally completed, without any further Hebraica to follow.

On May 22, 1860, Moritz Poppelauer (1824-1880) founded the bookstore M. Poppelauer and soon expanded it to include a publishing house. After his death, the business remained in the family and was continued from 1894 by his son-in-law Jacob Saenger, who died on February 14, 1939, eight weeks after the Nazis closed the business. The internationally known bookstore with an attached antiquarian bookshop specialized in Hebraica and Judaica and also sold Jewish ritual items, especially on the holidays.
