Engineering Instruments, Inc., Peru, Indiana, 1958



Engineering Instruments Inc. started out as the Lawrence Engineering Service in 1938, employing 10 people.  The company became know for the first 25-cent slide rule.  The founders, Lee and Vivian Lawrence, divorced in 1947.  The company became the wife's property, who gave it the new name.  It lasted another 20 years until a fire destroyed the factory.  Lee went on to found a plastics factory which, among other things, produced the Etch-a-Sketch toys.

  1. Indeed, progress be damned!
    Recently scored a Lawrence 10-B slide rule from a thrift shop for the princely sum of $2. Instrument is over 70 years young and is simple yet elegant. I've managed the former but not the latter...
    I hope to use it for another 30 years and get my money's worth. $2 is $2 after all...
    I hope to use it to design an aeronautical craft utilising the Magnus Effect. I've been reliably informed that there is a future in the design & manufacture of heavier-than-air devices. The Sonora Aero Club of California is apparently making great strides in that field of endeavour.
    In numero veritas,
