The man(1) command was already available in AT&T Version 2 UNIX.

Jonathan Gray found it in the "Combined Table of Contents" in Doug

edition manuals appeared in, and in both the "Table of Contents"
(page vi) and the body (page 89) of the printed UNIX Programmer's
Manual (June 12, 1972) from bitsavers.
