Charles Robert Sanger was an American chemist and professor at Harvard University.
Background
Sanger was born on August 31, 1860, in Boston, Massachusetts, United States, the son of George Partridge Sanger (1819-1890) and Elizabeth Sherburne (Thompson) (1819-1897). His great-grandfather, Zedekiah Sanger, was minister at Duxbury and South Bridgewater; his grandfather, Ralph Sanger, minister of Dover; and his father, a judge of the court of common pleas and United States district attorney for Massachusetts. His mother came of a family of Portsmouth, N. H. , sea captains.
Education
Early in Sanger's boyhood his father moved to Cambridge, and he was fitted for college at the high school there. Entering Harvard College in 1877, he displayed much interest in chemistry, was prominent in student activities, and was elected permanent class secretary in his senior year.
Graduated in 1881, he spent the next year in research work with Prof. Henry Barker Hill at Harvard, and the succeeding year in similar work at the universities of Munich and Bonn. He then returned to Harvard to continue his researches with Professor Hill and was granted the degree of doctor of philosophy in 1884.
Career
He remained at Harvard as an assistant until 1886, when he was appointed professor of chemistry at the United States Naval Academy, Annapolis. In 1892 he was made Eliot Professor of Chemistry at Washington University, St. Louis. He was called back to Harvard in 1899 as assistant professor of chemistry, to give the course on qualitative analysis previously given by Professor Hill.
Later, he also initiated a course on industrial chemistry. Upon the death of Hill in 1903, Sanger was promoted to a full professorship and appointed director of the chemical laboratory.
In the result of his researches, he was able to demonstrate a marked correlation between the degree of exposure to such wallpaper, the amount of arsenic in the excreta, and the intensity of the morbid symptoms. In cases where arsenic was present in wallpapers but where the formation of dust was precluded by a covering of paint or other paper, he was able, nevertheless, to demonstrate the absorption of arsenic by persons exposed to such wallpapers, and thus to confirm the conclusion of Gosio that in some way a gaseous effluvium containing arsenic was given off from them.
His last researches were concerned with the preparation and properties of pyrosulphuryl chloride and chlorosulphonic acid, the action of sulphur trioxide on silicon tetrachloride, and the detection of fluorine. He was editor of its Proceedings in 1909-10.

Personality
Sanger was quiet, scholarly, and methodical, and phenomenally accurate and careful in all his observations and deductions.
Quotes from others about the person
In its obituary, the Boston Globe said, "The death of Professor Sanger takes from the Harvard faculty one of its most distinguished scholars and teachers. "
