Friedrich Pustet GmbH & Co. KG is a German publishing firm, located in Regensburg. The original home of the Pustets was the Republic of Venice, where the name Bustetto is common. Probably in the seventeenth century, the founder of the Ratisbon line immigrated to South Germany, where one of his descendants, Anton Pustet, lived as a poor bookbinder in the Lower Bavarian borough of Hals (near Passau) at the close of the eighteenth century. To him and his wife Anna (née Scheuerocker) was born on 25 March 1798, a son, Friedrich Pustet.
