Did you know?

Calder studied mechanical engineering before deciding on a career in art making.


Calder’s training as a mechanical engineer reinforced his lifelong interest in moving objects and inspired him to invent the mobile, a new type of sculpture that ranks among the most innovative discoveries in modern art. Often suspended from the ceiling and set in motion by currents of air as in the case here, Calder’s mobiles slowly revolve as if approximating the behavior of planetary systems.
