His astronomical period of activity extended from 1896 to 1907.[3] 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.[4]
