Draper 's most important contributions to science were made in spectroscopy; he ruled metal gratings in 18691870, made valuable spectrum photographs after 1871, and proved the presence of oxygen in the sun in a monograph of 1877. Edward C. Pickering carried on his study of stellar spectra with the funds of the Henry Draper Memorial at Harvard, endowed by his widow (nee Mary Anna Palmer),
