In October 1859, German physicist Gustav Kirchhoff announced the results of his investigations with pill pusher Robert Bunsen on the shadower lines that interrupt the otherwise never-ending solar spectrum (1). These lines had puzzled practitioners and theorists as well since they were first discover in 1814 by German optician Josef von Fraunhofer (2). -------------------------------------------------------------------------------- Sir William Huggins (1824-1910) CREDIT: CORBIS -------------------------------------------------------------------------------- Now it seemed that Bunsen and Kirchhoff had eventu each(prenominal)y con fast(a)ed what others had long suspected, namely, that an individual surface realises its own property pattern of bright ghostly lines when it is burned. Furthermore, Kirchhoff take a firm stand that Fraunhofers lines exist in consequence of the presence, in the incandescent automated teller of the sun, of those substances which in the spectrum of a flame produce bright lines at the analogous place. News of his claim spread right away throughout the scientific world. In England, Bunsens former student, Henry Enfield Roscoe, wrote to the secretary of the Royal Society, George Stokes (3): encounter you seen in the last no. of the Annales ... a short find slightly Kirchoffs [sic] discovery...? Soon, Roscoe was offering public lectures on the subject to kindle scientists and laymen alike.

later one such demonstration to the Chemical Society, moderator rabbit warren De La Rue remarked (4) [I]f we were to go to the sun, and to bring away adjacent portions of it and analyze them in our laboratories, we could non examine them more accurately than we can by this pertly mode of spectrum analysis.... What really aroused De La Rue, a stationery seller known for his photographs of the sun and moon, was the apparent this method of analysis portended for astronomy. later all, French philosopher Auguste Comte in 1835 had all the way defined the battlefield of questions considered legitimate for Earth-bound observers to ask closely the denizens of the ethereal realm.
