FIRST PHOTOGRAPHS OF THE SOLAR SPECTRUM IN THE INFRARED: "Colour Photometry." & "The Solar Spectrum, from 7150 to 10,000." (Philosophical Transactions of the Royal Society of London, Vol. 177 for the Year 1886 Part I & Part II, pp. 423-456, 457-469).

William de Wiveleslie Abney (1843-1920) extended his interests to spectroscopy and was the first to suggest (1877) that stars with rapid axial rotation could be detected by broadened lines in their spectra - an idea later to have wide application. He then devised a red-sensitive emulsion and with it made the first spectroscopic analyses of the structure of organic molecules (1882) and the first photographs of the solar spectrum in the infrared (1887). Articles illustrated by Plates 24-28.
