Galileo's escapement Galileo's escapement is a design for a clock escapement, invented around 1637 by Italian scientist Galileo Galilei (1564 - 1642). It was the earliest design of a pendulum clock. Since he was blind, Galileo described the device to his son, who drew a sketch of it. The son began construction of a prototype, but both he and Galileo died before it was completed.
