Edmund Weiß (Austrian, 1837–1917) was an astronomer, illustrator, and professor whose celestial visions bridged science and aesthetics. A key figure in 19th-century Austrian astronomy, he directed the Vienna Observatory and published extensively on planetary motion, comets, and meteors. His Bilder-Atlas der Sternenwelt (1892) transformed complex astronomical data into dazzling lithographs - part star chart, part dreamscape—inviting both scholars and lay readers to navigate the heavens with wonder.
