Dumont Duoscopic Led The Way For 3D TV. Kind Of….

Just came across some information on the Dumont Duoscopic that made a short lived debut. On January 7, 1954 DuMont Laboratories demonstrated its Duoscopic television receiver, a display allowing simultaneous viewing of two programmes. Two receivers are mounted in the cabinet at 45 degrees to each other, one horizontal and one vertical, with a polarizing screen in front of each faceplate. The images are combined on a semi-translucent mirror angled at 45 degrees between the two tubes. By the look of some of these images it might have been used for 3D however as mentioned earlier it was really designed so two people could watch different shows on the same set.
