Abstract

In 1872, S. P. Sadtler (1847-1923), after studying under Bunsen and others, returned from Göttingen, with a Ph.D. in chemistry, carrying a hand-held emission spectroscope, which he used in laboratory experiments at the University of Pennsylvania and in his own laboratory. It is interesting to note that his son, S. S. Sadtler (1873-1954), also used the same spectroscope. In those days, emission was the only form of spectroscopy, other than the hot wire; that was the case until infrared was introduced by Coblentz about 1900.
