I had been looking for a reference that named whoever was responsible
for "Continental Morse", but could never find one! Thank you for
supplying this little tidbit of information...now, Morse joins
Uedemann and Baudot, as pioneering inventors, and Gerke joins
Gringmuth and Murray as those whose modifications bear the names of
the original inventors.
