Robert Taft (chemist and author)

Robert Taft (1894-1955) was an American chemist, educator, and author, primarily known for his work in the history of American chemistry and his contributions to physical organic chemistry.

Taft was born in Lincoln, Nebraska. He received his B.S. degree from Park College in 1916 and his Ph.D. in chemistry from the University of Kansas in 1925. He spent the majority of his academic career at the University of Kansas, where he taught chemistry and served as a professor for many years.

Taft's research interests encompassed various aspects of physical chemistry, particularly the study of reaction rates and mechanisms in organic chemistry. He is particularly remembered for his development of the Taft equation, a linear free-energy relationship (LFER) used to quantify the steric and polar effects of substituents on reaction rates. This equation remains a significant tool in physical organic chemistry.

Beyond his research contributions, Taft was also a prolific author and historian of science. His most notable work is Photography and the American Scene: A Social History, 1839-1889, published in 1938. This book explores the historical development of photography in the United States and its impact on American society. He also authored Across the Years on Mount Oread, a history of the University of Kansas, and various articles on the history of chemistry in America.

Robert Taft received numerous awards and honors throughout his career, recognizing his contributions to both chemistry and the history of science. He died in 1955.
