The number of undergraduate students, 2015-16 school year.
Donald Biggar Willett (1897-1981) attended the U of I from 1916 to 1922, but left the university just a few hours short of earning a bachelor's degree in civil engineering. During the 1930s, Willett moved to Los Angeles and opened a tax accounting business. He died in 1981 at age 83. His wife, Elizabeth Marie Henning Willett, was an avid investor who accumulated a fortune. She knew that her husband admired the U of I College of Engineering for its thriftiness and honesty, so in her will she left a gift to the college for research in memory of her husband. Mrs. Willett died in 1993 at age 91. The purpose of the Willett Professorships is to increase the distinction of the College and its departments by recognizing and stimulating intellectual leadership and outstanding research.
