Michael Lazar Biedermannn was born in Pressburg (now Bratislava). His interest in engraving took him to Vienna where he began his apprenticeship. The talent he exhibited was soon recognized and he won several prizes. Jews were not allowed to live and work in Vienna without a letter of permission. Biedermannn received his first “letter of tolerance,” in1792, that enabled him to reside in Vienna and work in his field. In 1798 he was commissioned to engrave the Imperial seal. His permission to work as a seal engraver and dealer in antiques was extended for another three years in 1801. Biedermann’s work enabled him to rise to the rank of court jeweler. He also acted as banker and merchant, moving away from engraving. He belonged to the enlightened section of Vienna Jews. Biedermann died at Baden bei Wien and was buried in Vienna.
