Hubert Sattler (21 January 1817 – 3 April 1904) was an Austrian painter who also signed works with the pseudonyms Louis Ritschard, E. Grossen, and Gottfried Stähly-Rychen.

As a boy, Sattler traveled with his father and first learned drawing and painting from him,[2] then entered the Academy of Fine Arts in Vienna at the age of twelve.

Sattler's cosmorama works, characterized by a high degree of detail, were sometimes displayed under lights in a dark room to paying customers looking through an aperture and often a magnifying lens.

[4] On her 1842 journey to the Near East, Ida Pfeiffer of Vienna met him and traveled with him for a while; in her published diary, she recorded how he was stoned by local people while sketching in Damascus.

"[6]From 1850 to 1852 the northeastern United States was treated to a cosmoramic exhibition that surpassed in quality and variety the host of panoramic shows deluging the country at this time.…Hubert Sattler arrived in Manhattan with a collection of some one hundred cosmoramic views, which he exhibited in five series of twenty-six pictures each, in a small room at Thirteenth Street and Broadway.…The correspondent of The New York Tribune echoed many witnesses when he asserted that the cosmoramas rose "to the dignity of works of art" and were superior to any "book of travels, panorama, or engraving.

[8] In addition to the cosmorama works, Sattler also painted smaller, more traditional landscapes, sometimes signing then with his name or initials, or with a number of pseudonyms, including Louis Ritschard, E. Grossen, and Gottfried Stähly-Rychen.
