Philippe van Lansberge

Johan Philip Lansberge (August 25 1561 – December 8 1632) was a Dutch astronomer. His name is sometimes written Lansberg, and his first name is sometimes given as Philip or Johannes Philippus. He published under the Latin name Philippus Lansbergius.

He is best known as the author of a set of astronomical tables, "Tabulae motum coelestium", for predicting planetary positions. These were later found to contain certain errors, in part because he erroneously did not accept Kepler's discovery of elliptical orbits.

He was born in Ghent in modern-day Belgium and died in Middelburg in the Netherlands. He served as a Protestant clergyman. Martinus Hortensius was one of his students, and Landsberge subsequently collaborated with his former pupil.
