Hugo Adolph Steinheil (born April 12, 1832 in Munich ; † November 4, 1893 there ) was a German optician and entrepreneur.

origin

His parents were Carl August von Steinheil (1801–1870) and his wife Magaretha Amalie nee. Steinheil .

Life

Hugo Adolph Steinheil, like his father, was interested in optics and astronomy from an early age . After studying in Munich and Augsburg , Hugo accompanied him to Austria and Switzerland in 1850/51 . In 1852 he returned to Munich, where he devoted himself entirely to optics.

In the years that followed, Hugo Steinheil actively supported his father in founding and expanding the company " Optical-astronomical Institution CA Steinheil ", which from 1855 operated as "Optical-astronomical Institution CA Steinheil & Sons". In 1862 he took over the management of the company - partly together with his brother, Eduard Steinheil (1830–1878). In 1866 he bought his father's shares in the company.

Camera lenses were an important area of ​​development under Hugo Adolph's Steinheil leadership . He benefited from the collaboration with his friend, the physicist Philipp Ludwig von Seidel . This collaboration resulted in the periscope , the first symmetrical camera lens, in the early / mid-1860s . The invention of the aplanate followed a little later with a light intensity of 1: 7 (1866). At that time there was a dispute with the German-English optician and John Henry Dallmeyer about the priority in the invention of the Aplanaten . In the same year - as it turned out independently, but a few weeks later - Dallmeyer had invented the very similar " Rapid Rectilinear ". In 1871 the wide-angle aplanat followed, the first photographic lens for copying images. As a forerunner of the later anastigmats , the Antiplanat was added in 1881. In 1887 he became a member of the Leopoldina . Since 1888 he was an extraordinary member of the Bavarian Academy of Sciences .

Around 1890 Rudolf Steinheil (1865–1930), son of Hugo Adolph, took over management of the company. In 1891, two years before his death, Hugo Adolph succeeded in publishing a book on optical construction together with Ernst Voit . Steinheil Point , a headland on the Danco coast of Graham Land on the Antarctic Peninsula, has borne his name since 1960 .

family

He (Dr. Adolph Steinheil) married Ida Erdinger (1840–1919), the daughter of a chief postal director , on September 25, 1858 in Munich "in the Protestant parish" .
