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.
