Anton Maria Schyrleus of Rheita

Anton (or Antonius) Maria Schyrleus (also Schyrl, Schyrle) of Rheita (1604–1660) ((Czech) Antonín Maria Šírek z Reity) was an astronomer and optician. He developed several inverting and erecting eyepieces, and was the maker of Kepler’s telescope. "Things appear more alive with the binocular telescope," he wrote, "doubly as exact so to speak, as well as large and bright."[1] His binocular telescope is the precursor to our binoculars.
