Johann Lantz or Lanz (1564 – 20 September 1638) was a German mathematician and Jesuit.[1][2]
Born in Tettnang on Lake Constance in 1564, he was admitted as novice in Landsberg in 1589.[1] He became a professor of Hebrew at the University of Ingolstadt. After 1609-1610 he left his place to his pupil Christoph Scheiner[2] and moved to the University of Munich.[1] He died in Munich in 1638.
He wrote several works on mathematics. He analyzed the four genres of numbers, then the astronomic fractions.[1] He is remembered also by Mario Bettini in his Aerarium philosophiae mathematicae (1648).[1][3][4]
