Samuel Philip Sadtler, Ph.D., LL.D. (July 18, 1847–December 20, 1923) was an American chemist,and the first President of the American Institute of Chemical Engineers in 1908.[1]


Sadtler was born at Pine Grove, Schuylkill County, Pennsylvania, the son of a Lutheran minister, and educated at Pennsylvania College (class of 1867), at Lehigh University (one year), at Lawrence Scientific School (BSc 1870), and in Europe at the University of Göttingen (PhD 1871).[2] As well as his professional activities, he was active in the Lutheran church.[2]

He died December 20, 1923, in Philadelphia.[2]


He was first a professor at Pennsylvania College (1871–74) and then the University of Pennsylvania (1874–91).[2] He then moved to the Philadelphia College of Pharmacy, where he was professor of chemistry until 1916 when he retired (and Emeritus professor afterwards).[2] He was author of: Hand-Book of Chemical Experimentation (1877); Industrial Organic Chemistry (1901; fourth edition, 1912); and Pharmaceutical Chemistry (1895; fourth edition, 1912), with Virgil Coblentz.

In 1907 to 1908 he was part of a discussion as to the formation of a society separate from the American Chemical Society for the newly recognised profession of chemical engineering. He was initially opposed to the proliferation of societies but said he would join a chemical engineering one if it was formed. On June 22, 1908, he welcomed interested people to a meeting at the Engineers Club, Philadelphia. The forty men present became Charter Members of the American Institute of Chemical Engineers, electing Sadtler as the President, a post he held till the end of 1909.[1] He made his Presidential address at the first Annual Meeting on December 28, 1908, and also established the Transactions of the AIChE in the same year.[1]
