In 1896, Charles Edouard Guillaume invented an alloy called "Invar", composed of iron and nickel, which has a very low coefficient of expansion. The new tower clocks built by the Balzer Family Clock Works and others. With Invar, the pendulum shaft is a simple, single shaft of metal. Of course, the hi-tech guys won out in the end.
