Donor Bill Nye acquired the slide rule as a gift from his parents over winter break in 1971. He used it from 1971 until 1975, in high school and in engineering school at Cornell University. Nye went on host "Bill Nye the Science Guy," a Public Broadcasting System television show for children.

This slide rule was copyrighted in 1960. The logo on it is that used by Pickett from 1964 until 1975.
