First appearance of pioneer-paper in astronomical photography, where he took wet-plate photographs of the moon-blocked sun during a total solar eclipse, and from them discovered solar prominences. - This was the first solar eclipse to be photographed, using the Kew Photoheliograph, a purpose-built combined camera and telescope designed by de la Rue and built in 1857 by Andrew Ross. De la Rue, Warren 1815-89, British scientist and inventor. Especially noted as an astronomer, he was a pioneer in celestial photography. He adapted the wet-plate process to lunar photography and invented (1858) for Kew Observatory a photoheliograph, the first device to give good solar pictures. His photographs of a solar eclipse in 1860 demonstrated that prominences observed at the sun's edge are of solar origin. De la Rue is known also for his research in chemistry, solar physics, and electrical discharge through gases.In 1860 De la Rue took the photoheliograph to Spain for the purpose of photographing the total solar eclipse which occurred on 18 July of that year. This expedition formed the subject of the Bakerian Lecture - the paper offered -. The photographs obtained on that occasion proved beyond doubt the solar character of the prominences or red flames, seen around the limb of the moon during a solar eclipse. In 1873 De la Rue gave up active work in astronomy, and presented most of his astronomical instruments to the university observatory, Oxford. Subsequently, in the year 1887, he provided the same observatory with a 13-inch refractor to enable it to take part in the International Photographic Survey of the Heavens.

First edition. The paper interpretates the photographs and the spectra taken of the sun under the total eclipse in 1893.""Joseph Norman Lockeyer (1836-1920), pioneer English astrophysicist. He made importent advances in the field of solar and stellar physics, and is responsible for naming the element helium, for emphasizing the two-branch theory of stellar evolution, and (jointly with Janssen) for the method of observing solar prominences without an eclipsee.""
