Johann Nepomuk Maelzel was German inventor, engineer, and showman who manufactured the metronome and several musical automatons. He didn't invent the metronome, but he improved upon its original design. He worked with Beethoven to give concerts where Beethoven would compose the music and Maelzel's automatons would perform around it. He gave shows using his automatons all across the US. Many of his mechanical performers are in museums now.
