Hippolyte Fizeau and Leon Foucault, were the two French physicists who first obtained a photograph of the surface of the Sun.
Warren De La Rue, although born in Guernsey, was his day the 'foremost celestial photographer' in his adopted country of England.
Pierre Jules Cesar Janssen, was one of the founders of solar physics who was the first to observe an unknown emission line in the spectrum of the Sun, which was later found to be produced by the gas Helium.
The earliest surveys of the face of the Sun were carried out by eye and later telescopes were used to project images onto a screen. Then photography was then used to capture its spots. Today images are obtained from the orbiting solar observatories.
