"Huggins perfected a spectroscope which, attached to his telescope, brought the prominent spectral lines of the brighter stars into view. Huggins's star spectroscope enabled astronomers to ask new questions and undertake new mensuration, and ultimately altered the boundaries of acceptable astronomical research" (ODNB). Ladd, the publisher, appears to have also been a manufacturer and retailer of spectroscopes and apparatus.
