This chromoscope belonged to John Hertzberg and later Helmer Bäckström when teaching photography at Kugliga Tekniska Högskolan in Stockholm. "Prof Dr Miethes Betrachtungs-Apparat", chromoscope for viewing color images is based on the first practical breakthrough for viewing color photography invented in 1891 by Fredrich Ives (1856-1937), in Philadelphia. Three negatives, one in each primary color (green, red blue) on a single plate. The slide was made directly from that plate and viewed in an apparatus that Ives called the "photochromoscope."
