Louis Gotlib grew up after slide rules had largely been replaced by electronic calculators. He graduated Phi Beta Kappa from The Johns Hopkins University and the University of North Carolina and has been a chemistry teacher for thirty-two years. One day around 1996 he saw a catalog from the MIT Museum Shop where old slide rules were being sold, bought a few, looked around on ebay and the web, and has been collecting ever since. Louis has been an Oughtred Society member since 1997 and was recently selected to serve on the Board of Directors. Louis has a special fondness for slide rules and calculating devices with a chemical orientation but his collection of 1300 items covers as many makers and specializations as possible. Louis has published papers and given presentations on slide rules, cell biology, and chemistry education. He also coauthors study guides for students taking standardized tests and plays chess. Louis can often be heard in his classroom saying things like "put that calculator away and just think for a moment!"
We are privileged to present HERE Louis's collection of slide rules.
