[CW] Telegraphists’ cramp: the emergence and disappearance of an occupational disease between 1875 and 1930

[Chris R. NW6V]

Thanks for posting the link Dave. I've been studying Haward's thesis, as
well as some of the main material she references, for the last few weeks.

As I mentioned in the "wild about bugs" meeting today, I discovered that
the British didn't use the term "telegrapher," instead referring to Morse
ops as "telegraphists." And referred to "glass arm" and "telegrapher's
paralysis," as "telegraphist's cramp." This cultural difference had blocked
research!

Haward's work helps flesh out the details in my "breaking a glass arm"
presentation, in development now. It got me pretty excited :-)
