Augustin Lajarrige (“un mecanicien de Marseille”) devised this ingenious mechanism, an automatic page turner (“tourne-page automatique”), in 1887. It was made for someone playing the piano–the pianist would advance the pages back or forward by simply moving the bar with the leg left or right. It is a simple but ingenious and elegant idea.
