Benjamin Bramer (1588-1652) was a German mathematician, architect and instrument maker, who was the adopted son, student, and eventually brother-in-law of the Swiss mathematician and astronomer Jost Bürgi (1552-1632). In 1618, Bramer published Etliche Geometrische Quaestiones (Several Geometric Questions).
