Daniels was born in
Minneapolis, Minnesota on March 8, 1889. Daniels began day school in 1895 at the
Kenwood School and then on to Douglas School. As a boy, he was fascinated with
Thomas Edison,
Samuel F. B. Morse,
Alexander Graham Bell, and
John Charles Fields. He decided early that he wanted to be an electrician and inventor. He attended Central and East Side high schools. By this point he liked chemistry and physics, but equally enjoyed "Manual Training." In 1906, he entered the
University of Minnesota, majoring in
chemistry and adding to the usual
mathematics and analytical courses some courses in
botany and scientific German. He was initiated into the Beta Chapter of
Alpha Chi Sigma in 1908. He sometimes worked summers as a
railroad surveyor. He took his degree in chemistry in 1910. The following year he spent half his time teaching and received an MS for graduate work in
physical chemistry. He entered
Harvard in 1911, paying for his studies partly through a teaching fellowship, and received a
PhD in 1914. His doctoral research on the
electrochemistry of
thallium alloys was supervised by
Theodore William Richards. In the summer of 1912, Daniels had visited England and Europe. After earning his PhD, Harvard would have sent him on a traveling fellowship in Europe, but
World War I broke out. So instead he accepted a position as an instructor at the
Worcester Polytechnic Institute, where, besides teaching, he found he had considerable time for research in
calorimetry, for which he received a grant from the
American Academy of Arts and Sciences. He joined the
University of Wisconsin in 1920 as an assistant professor in 1920, and remained until his retirement in 1959 as chairman of the chemistry department. Daniels is also known for writing several textbooks on
physical chemistry, including
Mathematical preparation for physical chemistry (1928),
Experimental physical chemistry, co-authored with J. Howard Mathews and John Warren (1934),
Chemical Kinetics (1938),
Physical Chemistry, co-authored with
Robert Alberty (1957). Some of these books went through many subsequent editions until about 1980. He was elected in 1928 a Fellow of the
American Association for the Advancement of Science (AAAS). He was elected to the United States
National Academy of Sciences in 1947 and the
American Philosophical Society in 1948. He was awarded the
Priestley Medal and elected to the
American Academy of Arts and Sciences in 1957. Daniels died on June 23, 1972, from complications from
liver cancer. He was survived by his wife, four children, and twelve grandchildren.{{cite web |url=https://www.nasonline.org/wp-content/uploads/2024/06/daniels-farrington.pdf He was inducted posthumously to the
