Auguste Wyten­hove was a French man­u­fac­tur­er of stere­o­scopes. His 1894–1895 cat­a­logue offered a broad range of stere­o­scopes and relat­ed view­ing devices. In 1897, the busi­ness was tak­en over by his son, Gus­tave. In 1898, Wyten­hove’s com­pa­ny was acquired by Louis Legendre. Legendre’s busi­ness was sub­se­quent­ly …

Louis Legendre was a French man­u­fac­tur­er of stere­o­scopes. He acquired the com­pa­ny of Wyten­hove in 1898. In 1899, Legendre intro­duced a sig­nif­i­cant inno­va­tion: a chain-based stere­o­scope equipped with an inter­change­able chain and stere­oview hold­ers. This sys­tem sim­pli­fied the exchange of stere­oviews and enabled com­plete col­lec­tions to …

The Auto­­mat­ic-inverseur is a device used for the auto­mat­ic trans­po­si­tion of stereo neg­a­tives and the pro­duc­tion of devel­oped pos­i­tive stere­oviews on glass. The device con­sists of a frame fit­ted with a cov­er enclos­ing the neg­a­tive and pos­i­tive plates. The frame includes an aper­ture through which light …
