Old Measuring Devices, Makers, Markers and Merchandisers of Instruments, Gauges, Rules, Squares & Tape Measures
Most of the information about rules available to me is still not yet included here. Information listed here was hastily gathered and posted on this web page without serious consideration to style and with minimal proofreading.

Old Measuring Devices; the Makers, Markers and Merchandisers of Instruments, Gauges, Rules, Squares, Scales & Tape Measures
An incomplete listing of 1,500+ Makers, Markers and Merchandisers of Instruments, Gauges, Rulers, Squares, Tape Measures, Scales, Thermometers and Barometers described in over 6,000 factoids.

The Known Working Years provided below only includes the information recorded here in this list. These years will be updated as this ’work–in–progress’ continues.

There were many more markers of tools than makers; part of the fun is separating the makers from the markers.

      RUBBER GLOVES IN SURGERY

      In the early 1890s the head surgeon at Johns Hopkins was the famous Dr. W. S. Halsted, and the head nurse in the operating rooms was Miss Caroline Hampton. Dr. Halsted, a bachelor, was in love with Miss Hampton. About this time Miss Hampton's hands, which had suffered greatly from immersion in the antiseptic fluids, carbolic acid, and bichloride of mercury, had reached the point where she could no longer carry on. Dr. Halsted's concern for Miss Hampton was two-fold, an interest in her personal well-being, and in having her assistance in carrying out the operating room technique. After trying out various experiments to no avail, he finally hit upon the idea of having made for her thin rubber gloves, which would afford the desired protection to the skin of her hands. Dr. Halsted went to a manufacturer of rubber gloves, stated his problem, and asked to have a pair of thin rubber gloves with gauntlets made for Miss Hampton. This was done and soon Miss Hampton was wearing rubber gloves in the operating room. This experiment, however, demonstrated the practicability of the use of rubber gloves in a surgical operation. The Doctor married the girl and the rubber manufacturer who perfected the gloves was our own Goodyear's India Rubber Glove Company.

    • Laroy S. Starrett (1836-1922) initially patented and manufactured utilitarian items like a meat chopper, food press or washing machine. Starrett formed the ATHOL MACHINE COMPANY on June 3, 1868 to manufacture these products. Detailed description of early Starrett business is found in Makers of American Machinist’s Tools - A Historical Directory of Makers and Their Tools by Kenneth L. Cope, Astragal Press, 1994.
    • Starrett’s first tool was the combination square he invented in 1876. Unhappy at ATHOL MACHINE COMPANY he was selling the square on his own. The RICHARDSON MACHINE SHOP in Athol, Massachusetts was making them for Starrett. The result of a work stoppage at Richardson on his squares triggered by legal action from ATHOL MACHINE COMPANY is that Starrett purchased the Richardson manufacturing section and started L.S. STARRETT company. A detailed description of early Starrett history is found in Makers of American Machinist’s Tools - A Historical Directory of Makers and Their Tools by Kenneth L. Cope, Astragal Press, 1994. p. 73 and Appendix II.
