Henri Georges de France (7 September 1911 Paris – 29 April 1986 Paris) was a pioneering French television inventor. His inventions include the 819 line French standard and the SECAM color system. He was also apparently behind the HD-MAC high-definition standard.
On December 6, 1931, De France founded the Compagnie Générale de Télévision in Le Havre, making television sets with a vertical definition of 60 lines. In February 1932, De France made several transmissions over a distance of 7 km from the "Radio-Normandie" station in Fécamp. These signals were received by a few people located over 100 km away. In October 1932, he achieved a definition of 120 lines. In 1956, he patented the SECAM color television system. On October 1, 1967 at 2:15pm CET, la deuxième chaîne switched from black and white to color using SECAM.
De France is interred at Jarnac, the same town where former president François Mitterrand is buried.
The public passage near France Télévisions buildings in Paris is named Esplanade Henri de France.

Famous quotes containing the words henri and/or france:
“Science is built up with facts, as a house is with stones. But a collection of facts is no more a science than a heap of stones is a house.”
—Jules Henri Poincare (1854–1912)
“It is not enough that France should be regarded as a country which enjoys the remains of a freedom acquired long ago. If she is still to count in the world—and if she does not intend to, she may as well perish—she must be seen by her own citizens and by all men as an ever-flowing source of liberty. There must not be a single genuine lover of freedom in the whole world who can have a valid reason for hating France.”
—Simone Weil (1909–1943)
