[GreenKeys] Is 2006 the Centennial for Birth of Teleprinters?

Well...things like that always get a little bit fuzzy.

First, there is the very old line of printing telegraphs that culminated
in the old stock ticker.  That doesn't have much to do with the 
teleprinters we are talking about, because it didn't use an efficient
code.  So we have Baudot, circa 1875 for that invention, and he had
a printer to go with it.  There was also the Rowland company in the
1880s-1890s that had a teleprinter.  Charles Krum and then Charles
and Howard Krum devised a lot of teleprinter equipment early in the
1900s.  The Start-Stop method of synchronization, which leads to
the teleprinter as we know it, was invented by Howard Krum, who filed
for a patent in 1910 that was issued in 1918.  Western Electric and
Kleinschmidt Electric also produced teleprinters using the principle;
and it was several years before all the patent issues were sorted out.
That resulted in a merger of the Kleinschmidt and Morkrum companies.

If you look at that patent #1,286,351 it is hard to recognize the
teleprinter as we know it.

It's been a while since I looked at Irv Hoff's stuff, so offhand I
don't know what he is referring to with a 1906 date.
