Who was the original Cliff?

Born in a small, rural Nebraska town named Rising City, Cliff Hillegass epitomized the notion of the "self starter." Fueled by his early love of literature, Cliff was determined to go to college. To finance his education, Cliff held down two paper routes in addition to caring for his family's Jersey cows.

As a college student in the dust bowl days of the "dirty '30s," Cliff continued to pursue his love of learning. While a graduate student in geology and physics at the University of Nebraska, Cliff got married and started his first full-time job as a college bookstore representative for Long's College Bookstore (now the Nebraska Book Company). The numerous contacts Cliff developed through his work at the bookstore were crucial to the launch of CliffsNotes many years later.

One Toronto contact, Jack Cole, owned Coles, The Book People, which produced study guides called Cole's Notes that were published in Canada. During one momentous conversation, Cole suggested that American students would likely welcome a U.S. version of the notes. With that idea, Cliff launched CliffsNotes in August 1958, with a line of 16 Shakespeare study guides.

Working out of Lincoln, Nebraska, Cliff built the company that produces the most widely used study guides in the world. Cliff's message for students was to use CliffsNotes to better understand literature.

In 1998, Cliff sold CliffsNotes, Inc., and the brand lives on today as part of John Wiley & Sons, Inc. In May 2001, Mr. Hillegass passed away at the age of 83.
