Michael O'Leary provided the inspiration for starting this site. His drive to understand the K&E line of Slide Rules and share that information with all is what this site is about. Michael's spirit lives on.
The idea of an individual collector gathering massive amounts of information and sharing it with the world with out regard of monetary gain or the effects on the collecting market is unparalleled. Michael's spirit lives on.
The impact of Michael on the ISRG email group and slide rule collecting in general is large. His tireless efforts will be remembered for a long time. Michael's spirit lives on.
