As anyone who has written by hand over the course of a lengthy sitting knows, comfort can quickly become an issue. The October 22, 1853 issue of Scientific American featured an invention recently patented by Joseph G. Goshon of Shirleysburg, PA and William H. Towers of Bucyrus, OH called the "Elastic Pad for Penmen."

The Elastic Pad, shown above, was made of either India rubber or an air cushion with a convex outside and concave inside. The pad was secured to the arm at the elbow or any other point under distress by a leather band fitted with a number of buttonholes to allow for various arm sizes. By giving flexible support to the arm, the device claimed to help fingers from cramping and becoming numb. "One of these pads or cushions will last for a number of years, and besides being a relief to the writer, will soon save the amount paid for it in preserving the coat sleeve."

I can’t say that I’ve ever worn through a coat sleeve from writing at length, but I could’ve really used something like this while grueling through 3 hour written exams in college. Now, looking around the office, I’ve noticed a number of people using mouse pads and keyboards with gel wrist pads attached—a true testament to the problem identified and confronted by Goshon and Towers over 150 years ago.
