Born in Paris, France, his most famous inventions are:
- the anamorphic widescreen process, using an anamorphic lens system called Hypergonar, that resulted in the CinemaScope widescreen technique, and
- the co-invention, with George Willis Ritchey, of the Ritchey–Chrétien telescope, an improved type of astronomical telescope, employing a system now used in virtually all large research telescopes.
He spent part of his early astronomical career at the Nice Observatory, which was close to his house, the Villa Paradou. The Villa was built by famous French architect Charles Garnier[2][citation needed] who also built the Opera of Paris. In 1995, the abandoned villa was acquired by the artist Rainer Maria Latzke, who restored it and added new murals to the existing frescoes.
Chrétien was one of the founders of the Institut d'optique théorique et appliquée and professor at the French "grande école" SupOptique (École supérieure d'optique).

- Valz Prize from the French Academy of Sciences (1931)[4]
- The crater Chrétien on the Moon is named in his honor.[5]

Henri-Jacques Chrétien (1º febbraio 1879 – 6 febbraio 1956) è stato un fisico e astronomo francese. È l'inventore della lente hypergonar (1925) dalla quale deriva il sistema cinemascope, per la ripresa e la proiezione di film su schermo gigante, i cui primi esempi pratici (cortometraggi ed il film La tunica) si ebbero solo nel 1953, prima negli Stati Uniti e poi anche in Europa.Другой контент может иметь иную лицензию.
