Richard Advertisement ‘Le Vérascope, Les Homéoscopes’

In 1893, Jules Richard intro­duced the com­pact 45 x 107 glass stere­oview for­mat togeth­er with the Véras­cope stereo cam­era. The sys­tem achieved con­sid­er­able suc­cess and con­tributed to a revival of stereo pho­tog­ra­phy in France. Véras­cope became a reg­is­tered trade­mark, and a com­pre­hen­sive prod­uct line was devel­oped around the new com­pact for­mat, com­pris­ing cam­eras, stere­o­scopes, and acces­sories in var­i­ous price cat­e­gories. In the ear­ly 1900s, the Tax­iphote was intro­duced. It was the first tray-based stere­o­scope and served as a mod­el for com­pa­ra­ble designs pro­duced by man­u­fac­tur­ers in France and Germany.
Richard’s com­pa­ny devel­oped into the lead­ing brand in stereo­scop­ic equip­ment and made stereo pho­tog­ra­phy acces­si­ble to a broad­er ama­teur mar­ket. The prod­uct names Véras­cope and Tax­iphote were wide­ly used as gener­ic terms for stereo cam­eras and stereoscopes.
