Georg Joachim Rheticus

Georg Joachim de Porris, also known as Rheticus, was a mathematician, astronomer, cartographer, navigational-instrument maker, medical practitioner, and teacher. He is perhaps best known for his trigonometric tables and as Nicolaus Copernicus's sole pupil. He facilitated the publication of his master's De revolutionibus orbium coelestium. ^{Georg Joachim Rheticus, Austrian cartographer and instrument maker (d. 1574)}
