Johann Hommel, also called Johannes Homelius, Hummelius or Hummel (1518 to 1562), was a German astronomer and mathematician, born at Memmingen and dying at Leipzig. He was appointed professor of mathematics at the University of Leipzig in 1551. He is known for a zigzag line system of graduations on instruments, which Tycho Brahe obtained from him; in 1552 or 1553 Richard Cantzlar introduced transversal dot lines in graduations as a variant of the zigzag system that Hommel had introduced. His work is discussed by historians of the Leipzig university and of astronomical observatories, including a study of Hommel as surveyor, cartographer, astronomer and instrument maker in the middle of the sixteenth century, and the Camerarius edition project covers the mathematical sciences in connection with him. The lunar crater Hommel is named after him, and the Mathematics Genealogy Project lists him.
