John Prince
November 13, 1941 – December 6, 2005

John specialized in collecting K&E rules, with a strong interest in Pickett as well. In 2002, John described how he started with slide rules in 1960: "I used a K&E 4181-3 ; we were mandated to use either a 4081-3 or 4181-3 in our freshman slide rule class. I chose the cheaper (very important to a married 18 year old) rule and never regretted it despite the dire predictions from some faculty about dimensional stability and durability. I never really needed a more complex rule while working in graduate school as an electrical engineer." [ISRG, message 15929]
