Athanase Clouzard and Charles Soulier first formed a company in 1853 together with Louis This and several other partners. (That company was located first at 10, Rue Croix-des-Petits-Champs and then at 156, Rue du Temple in Paris.)

​

In 1854 Clouzard and Soulier created a separate company from This and launched a business of taking and selling their own stereoviews. (The original business was sold to their former partners Jean-Gabriel Bernard and Frederic-Alphonse Voigt in 1856.) The company was based initially at 47, Rue Saint-André des Arts and, most likely at some point in 1856, moved to 28 Rue des Grands Augustins right next to the previous address.

​

The company of Clouzard and Soulier was one of the main competitor of Claude-Marie Ferrier in the making of stereoscopic photographs on glass. Already in 1854 they started supplying Dubosq. In return Dubosq would supply them with his stereoscopes.

​

In 1855 the company participated in the International Exhibition in Paris where it received a second class medal for their stereoscopic views. In 1857 the firm receives a medal at the art exhibition in Brussels.

​

By 1859 the firm had more than 700 views of France, Germany, Austria, and Spain.

​

On the 9th of June, 1859 Clouzard sold his part of the company and the rights to the whole collection of stereoviews to Soulier. The same year Soulier formed a new company with Claude-Marie Ferrier and his son.
