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:
“A wise woman never yields by appointment. It should always be an unforeseen happiness.”
—Stendhal [Marie Henri Beyle] (1783–1842)
“But as some silly young men returning from France affect a broken English, to be thought perfect in the French language; so his Lordship, I think, to seem a perfect understander of the unintelligible language of the Schoolmen, pretends an ignorance of his mother-tongue. He talks here of command and counsel as if he were no Englishman, nor knew any difference between their significations.”
—Thomas Hobbes (1579–1688)
