Walter Augustin Villiger
Walter Augustin Villiger (1872–1938;〔(【引用サイトリンク】 Who's Who in Comet History: V )〕 his first name is sometimes spelt Walther) was a Swiss astronomer and Carl Zeiss engineer who discovered an asteroid while was working in Munich, Germany. He also participated in the observation of comets.
His astronomical period of activity extended from 1896 to 1907.〔(【引用サイトリンク】 Query Results for "Villiger, W" )〕 In 1924, less than a year after the first planetarium had been opened at the Deutsches Museum in Munich, Walther Villiger suggested a new, improved Zeiss planetarium projector. This new Zeiss, known as the ''Mark II'', was designed for much larger theatres than the previous model —up to 23 metres ().
Asteroid 1310 Villigera is named after him.〔((1310) Villigera ) - Lutz Schmadel - Dictionary of Minor Planets names - p. 105〕
