Horace G. Martin



"Having experimented for some time on automatic transmitters and having
the occasion to observe the very interesting achievements of other workers
in the automatic field. I decided that there was a demand for a small, simple
and portable sending machine which, while being automatic or nearly so,
would, as nearly as possible, retain the merits but not the demerits of the
old Morse key."
Horace G. Martin, February 1903
