Looks like it was forked from some predecessors ( https://en.wikipedia.org/wiki/Secure_Shell#OSSH) but doesn't go into the history much more than that. I remember telnet, where there any encrypted predecessors before the ssh family?

OpenSSH was forked from the original SSH (version 1) code by Tatu Ylönen after it went closed source in the mid-1990's IIRC.

Telnet over SSL.
