Philippe, Jean-Adrien

Jean-Adrien Philippe was a French watchmaker.

Jean-Adrien Philippe was born 1815 in Bazoche-Guet (France), the son of a watchmaker. He was selected as the second partner of Antoine Norbert Count de Patek after whose cooperation with the co-founder of the company Patek Philippe, the watchmaker Francois Czapek, had failed. (The company was then called Patek, Czapek & Co..)

Jean-Adrien Philippe had already enriched the watch history by a new revolutionary invention the crown winding, developed by him 1842. This invention earned him a gold medal at the Paris Exposition of 1844; it was patented 1845. On said exhibition he met Antoine Norbert Count de Patek, who recognized his talent and made him shareholder with a third of the company.

From January 1, 1851, his name was included in the new company name Patek Philippe.

With the death of Count de Patek in 1877 Jean-Adrien Philippe took over the sole management of the company. 1889 Patek Philippe patented a mechanism for a perpetual calendar, which did not require manual correction. In January 1891, three years before his death, Philippe transferred the management of his son Joseph Emile.

Jean-Adrien Philippe died on January 5, 1894 in Plainpalais in Geneva.
