A 3D-Printed 19th c. Psych Instrument – See Kirschmann’s Colour Mixer in Action!

Erich Weidenhammer, a graduate of the Institute for the History and Philosophy of Science and Technology at the University of Toronto, has recently remade a Farbenmisch-Apparat nach Kirschmann (“Colour mixing apparatus after Kirschmann’s design”) via 3D printing. This colour mixing apparatus was designed by August Kirschmann, a German-born psychologist who trained with Wilhelm Wundt. Kirschmann succeeded James Mark Baldwin as head of the Psychological Laboratory at the University of Toronto in the late-nineteenth century. He also designed several laboratory instruments.

Weidenhammer set out to recreate Kirschmann’s instrument and fortunately discovered a colour mixing apparatus among the psychology instruments stored at the University of Toronto (now a part of the University of Toronto Scientific Instruments Collection). The full process of recreation, and the significance of this kind of colour research during Kirschmann’s time, is discussed in detail in a recent blog post by Weidenhammer. The recreated Farbenmisch-Apparat nach Kirschmann can be seen in action in the video above.
