As I recall, SSB was first used by Western Electric
for their overseas cable (?)telehphone circuits in the 1920
to 1922 time frame.  There were some early published ssb
transmitter info in I think the 50 year anniversary issues
of QST.  The last time I worked on microwave systems,
the mux cards were all ssb channels, about 3 khz wide
upper and lower per channel.
Amateur usage and experiments started in the
late 40's and early 50's.  So unique at that time the pubs
like QST and CQ had separate columns.
