Hemdé
Hemdé was a trademark for photographic accessories and stereoscopes, introduced by Maurice Delécaille in 1902. Paul Sorel joined Delécaille’s business five years later. Together with Émile Cuny, they patented a design for a mechanism used in an advanced tray-based stereoscope. This development marked the beginning of the Hemdé stereoscope.
