Heinrich Erfle (April 1, 1884, Dürkheim – April 8, 1923, Jena) was a German optician who spent most of his career at Carl Zeiss. In 1917 he invented the first wide-field eyepieces for telescopes and binoculars. During his short life he developed a number of new designs for telescopes and eyepieces.
