WILDER DWIGHT BANCROFT

'Wilder Dwight Bancroft' (Middletown, Rhode Island on 1 October 1867 - 7 February 1953) was an American physical chemist.
He received a BA from Harvard University in 1888, a PhD from Leipzig University in 1892, and honorary SCDs from Lafayette College (in 1919) and Cambridge University (in 1923).
He was an assistant chemistry instructor at Harvard University from 1888-1889 and 1893-1894, then a full instructor from 1894-1895. He then became an assistant professor at Cornell University in 1895, then a full professor (at Cornell) in 1903.
Bancroft was trained by Wilhelm Ostwald and Jacobus Henricus van 't Hoff, and introduced a number of thermodynamic and colloidchemical concepts in American physicochemistry. He is known for the so-called Bancroft rule: a predominantly hydrophilic emulsifier stabilises an oil-in-water emulsion, whereas a predominantly hydrophobic emulsifier stabilises a water-in oil emulsion.
The lunar crater Bancroft is named in his honor.
