Gustave Le Gray (1820-1884) was an important early French photographer. Trained as a painter by some prominent artists, he switched to the medium of photography in the 1840s (today we'd call him an "early adopter"). He became in time the official photographer to Emperor Napoleon III.
Much of his work consisted of landscapes and seascapes; he also did portraits.
