Inventor acetate yarn and varnishes

Henry Dreyfuss was born in Basel, Switzerland (Basel, Switzerland); his older brother, Camille Dreyfus (Camille Dreyfus), has also been quite successful inventor. Their father worked in the chemical industry. The brothers finished school in Basel, and then continued their education at the Sorbonne, Paris (Sorbonne, Paris). In 1904 Henry Dreyfuss received a PhD. Shortly thereafter, the brothers took up the experiments; laboratory they founded themselves in the corner of his father`s garden. The first major breakthrough for Dreyfus was the discovery of synthetic indigo dye.

In 1908 Dreyfus have developed a cellulose acetate; active research open the material and its properties brothers were engaged, in fact, until the end of his days. It was originally planned to simply create a safe flame retardant substitution tsellyuloida; later, however, it became clear chtoveschestvo brothers opened a much more promising.

By 1910 th Dreyfus brought to mind the plastic film and acetate fibers.

December 12, 1912 the first Henry and Camille founded the factory in Basel; produce at the factory they were refractory celluloid. In 1913, the firm `Cellonit` was founded, specialized in the development of new materials. That same year, the brothers created the first samples of acetate yarns from continuous fibers; for the most part, however, the company is engaged in film production for the needs of kinodela or personal hygiene items. One of the largest customers of the company was the Parisian firm `Pathe`, specialized in the production of film equipment. Produces Dreyfus and varnishes used in the pro duction zeppelins and airplanes; the demand for such coatings grew quite quickly - the airline industry at that time was on the rise.

During the First World `Cellonite` were the only ones who responded to the call put forward by the British military in the mass production of fireproof cellulose acetate on the basis - primarily in the form of a dope. In 1916 the brothers moved to Britain, where he personally supervised the construction of a new factory. Factory manager special trust, in which the brothers and Clavel owned 50% -2 shares. Soon the factory was completed; in January 1917 a contract was signed for the supply of 40 tonnes of lacquers. Initially, the production did not have enough raw materials, but later problems has been removed; over time, the range of products has expanded greatly - first of all, due to all sorts of aircraft industry orders. By 1918 th at the Henry Dreyfus employed 14,000 people.

In November 1918, the war was over, the contracts have been canceled in the paint, and the company has begun the hard times. Back in February 1918 Camille Dreyfus left for America; He returned only in July of 1919. Brothers jointly launched a new production; they made an artificial fiber. The technical and administrative aspects of the British arm of Henry Dreyfuss worked almost until his death. Revenues from the company Dreyfus on paper were worthy, but to pay dividends to the company began only after Henry`s death. Dealers Dreyfus, Jr., was a talented - he was able to considerably advance its development, surpassing almost all known at the time of the competition.

Henry Dreyfuss died in 1944; at the time of the death of the inventor there were more than 2000 different patent applications.
