Wild Dwight Bancroft
Wilder Dwight Bancroft (born October 1, 1867 in Middletown , Rhode Island , † February 7, 1953 in Ithaca (New York) ) was an American physical chemist .
Life
Bancroft studied at Harvard University , where he received a BA degree in 1888 and a Ph.D. he received in 1892 at the University of Leipzig with Wilhelm Ostwald . His teachers included Wilhelm Ostwald and Jacobus Henricus van 't Hoff .
Bancroft taught from 1888 to 1889 and from 1893 to 1894 as an assistant (assistant instructor) chemistry at Harvard University , in 1894 and 1895 he was fully active as a teacher (full instructor). From 1895 he taught assistant professor at Cornell University , from 1903 he was there professor (full professor).
He introduced various approaches to thermodynamics and colloid chemistry in physical chemistry in the United States. He became known for Bancroft's rule , named after him , which states that a predominantly hydrophilic emulsifier stabilizes an oil-in-water emulsion , while a predominantly hydrophobic emulsifier stabilizes a water-in-oil emulsion.
From 1896 to 1933 he published the first American journal in his field of physical chemistry, the Journal of Physical Chemistry . The publication of the magazine had to be suspended for financial reasons as a result of the economic depression in America.
Honors
He was awarded an honorary Doctor of Science (SCD) doctorate from Lafayette College in Pennsylvania in 1919 and from Cambridge University in 1923 . In 1913 he was elected to the American Academy of Arts and Sciences , in 1920 to the National Academy of Sciences and the American Philosophical Society .
In his honor, the Bancroft crater on the moon was named after him.
