Gift of Edward T. Wright of Odenton, Maryland.
Edward Wright (on left) received his B.A. with Honors in Mathematics from Rhodes College (formerly Southwestern at Memphis) in 1968, followed by his Ph.D. in Mathematics from the University of Notre Dame in 1973. Ed's thesis was on compact Kahler manifolds that admit Killing vector fields. After graduate school Dr. Wright was a visiting assistant professor at Notre Dame for one school year,then worked as an (applied) mathematician for the Department of Defense for 39 years. Ed retired 2014. Ed writes: "The only time I ever used a slide rule was in high school physics (1963/64). I started collecting them off of Ebay in the 2004/5 time period. I continue to marvel at how much was accomplished with these instruments. I am in the process of down sizing the modest collection that I have, and wanted them to go some place that will preserve this part of the technology."

REF Beatly I-Q Slide Rule
Beatly I-Q Slide Rule
Made in U.S.A. by K&E, distributed by Edward E. Babb & Co.
Front Scale: Mental Age [ Chronological Age ] Intelligence Quotient
Back: Directions
Notes: Copyrighted by Dr. Bancroft Beatley in 1922 while working on his doctorate thesis.(See Slide Rule Who's Who. The slide calculator is an unusual (certainly for K&E) single-purpose device for determining Intelligence Quotient (IQ) given a youngster's physical age and his mental age (apparently determined by a standardized test). More specifically, the rule is designed for use in calculating the IQ of young people from ages 3 to 18 with IQs ranging from 30 to 170.
