In October 1859, German physicist Gustav Kirchhoff announced the results of his investigations with chemist Robert Bunsen on the glum lines that interrupt the otherwise continuous solar spectrum (1). These lines had gravel practitioners and theorists analogous since they were first observed in 1814 by German optician Josef von Fraunhofer (2). Now it seemed that Bunsen and Kirchhoff had finally confirmed what others had languish suspected, namely, that an individual admixture produces its own characteristic pattern of lucent spectral lines when it is burned. Furthermore, Kirchhoff take a firm stand that Fraunhofers lines subsist in consequence of the presence, in the incandescent standard zephyr of the sun, of those substances which in the spectrum of a flame produce bright lines at the same place. News of his claim spread quickly throughout the scientific world. In England, Bunsens former student, Henry Enfield Roscoe, wrote to the secretary of the munificent Society, G eorge Stokes (3): agree you seen in the last no. of the Annales ... a go around account about Kirchoffs [sic] discovery...? Soon, Roscoe was offering public lectures on the line of business to arouse scientists and laymen alike.
After one such presentation to the chemical Society, temperrator rabbit warren De La Rue remarked (4) [I]f we were to go to the sun, and to loan away close to portions of it and analyze them in our laboratories, we could not determine them more accurately than we can by this new mode of spectrum analysis.... What really activated De La Rue, a stationer cognize for his photographs of the sun and moon, was the potentiality this met! hod of analysis portended for astronomy. After all, French philosopher Auguste Comte in 1835 had distinctly defined the domain of questions considered legitimate for Earth-bound observers to choose about the denizens of the aerial realm.
