Lazarus Posen Witwe (Lazarus Posens widow) was unique among 19th- and 20th-century German silver manufactories in that its owner and principal director was a Jewish woman. The firm was founded in Frankfurt on the Main in 1869 by Brendina Wetzlar, the widow of Lazarus Jacob Posen, a silversmith and retailer of Polish descent. Under the widow Posens stewardship, the firm became the largest supplier of Judaica in the late 19th century. Her son Jacob L. Posen joined the firm by 1880, and by 1900, the companys large staff of chasers and engravers were producing some of the finest silver in the country. They received a royal warrant in 1903 and opened a second shop in Berlin. The firm followed all the latest continental trends incorporating both Danish and Austrian styles into their output. In the 20th century the firm was under the direction of Brendinas grandsons Jakob, Hermann and Moritz Posen. The exact date of the companys closure is not known, but it seems certain that the wealthy Jewish-owned firm was a victim of the terrors of the Nazi regime. Articles by Posen Witwe are today held in both the Frankfurt Historical Museum and the Frankfurt Jewish Museum.
