Atsuko Tanaka
Inspired by her outdoor installation "Pink Rayon" (1955), Tanaka created "Bell" in 1955. It consisted of a string of twenty electric bells and a button with the sign "Please feel free to push the button, Atsuko Tanaka". In early versions of "Bell", the bells were laid at two-meter intervals with each other to surround a gallery room. Once visitors pressed the button, it would make the bells ring in sequence for two minutes. The arrangement of the bells was adapted to different spaces at later exhibitions.
