Ivan Kulibin

Ivan Petrovich Kulibin (April 21, 1735 – August 11, 1818) was a Russian mechanic and inventor.

Kulibin also designed projects for tower clocks, miniature "clock-in-a-ring" types and others.

Kulibin's project was praised by Leonhard Euler and Daniel Bernoulli, but was never realized.

After 1780 Kulibin worked on possibilities for a metallic bridge, but these projects were also rejected by the government.

In 1791 Kulibin constructed a push-cycle cart, in which he used a flywheel, a brake, a gearbox and roller bearing.

He assembled the famous Peacock Clock created by James Cox and purchased by Catherine the Great, the only large 18th century automaton that has come down to us in its authentic configuration without any change or modification.
