Eduard Aber

Eduard Aber was born into a well-to-do Jewish family in Rawitsch. In 1833, Eduard followed his uncle August Hirschwald to Berlin and helped him manage the Hirschwald bookshop on Gross Burgstrasse 25, which August had founded in 1816. After August's death in 1848, Eduard took over the bookshop, running it together with his cousin Ferdinand Hirschwald. Eduard was known to be "an unusually capable and active man." Under Eduard's direction, the business began booming, and the Hirschwald bookshop became a leading publisher of notable scientific and medical journals on the European continent. Eduard was internationally renowned for his firm's high-quality academic publications.
