He was born in Ingolstadt as Philipp Bienewitz (or Bennewitz). At age eleven, the son of mathematician, astronomer and cartographer Peter Apian started to study mathematics at the University of Ingolstadt. Later, aged 18, he studied in Burgundy, Paris and Bourges.
Returning in 1552 he became professor. As a Protestant he had to leave in 1569 due to Jesuits and the counter reformation. At the University of Tübingen he lectured for 14 years until he lost this position in 1583 for refusing to negate Calvinism. He died in Tübingen.
In 1554, Duke Albrecht of Bavaria orders Apian to create a map of Bavaria for the Bairische Chronik of Johannes Aventinus written 1526 to 1533. In seven years, Apian travelled through Oberbayern and Niederbayern, Oberpfalz, Archbishopric Salzburg and Bishopric Eichstätt. After two years work, a 5 x 5 meter sized map in scale 1:45.000 was finished, to be coloured by Bartel Refinger.
Having been in the residence's library since 1563, it was destroyed by a fire in 1782.
Smaller Bairische Landtafeln based on the map were ordered by Philipp Apian in 1566 from Jost Amman as 24 tables of scale 1:144.000 anfertigen. It is said that the accuracy was only surpassed in 19th century and that Napoléon Bonaparte used them when invading Bavaria.
Abraham Ortelius published them as ex tabula Philippi Apiani.
