Yerkes 41-inch reflector is a 40-inch aperture (101.6 cm) reflecting telescope at the Yerkes Observatory, that was completed in 1968. It is known as the 41 inch to avoid confusion with a 40 inch refractor at the observatory.
The Swedish 1-m Solar Telescope, with a lens diameter of 43 inches, is technically the largest, with 39 inches clear for the aperture.The second largest refracting telescope in the world is the Yerkes Observatory 40 inch (102 cm) refractor, used for astronomical and scientific observation for over a century.
William Albert Hiltner (27 August 1914 – 30 September 1991) was an American astronomer, noted for his work leading up to the discovery of interstellar polarization. [1] [2] He was an early practitioner of precision stellar photometry, and a pioneering observer of the optical counterparts of celestial x-ray sources.

The 40-inch (1.02 m) Refractor, at Yerkes Observatory, the largest by famed lens makers Alvin & Clark. The era slowly came to end as large reflecting telescopes superseded the great refractors. In 1856–57, Carl August von Steinheil and Léon Foucault introduced a process of depositing a layer of silver on glass telescope mirrors. Silvered ...
