Character codes predate computers. CR and LF codes date to 1901.

  Even earlier than that. CR and LF go back to Baudot code (which is where term 'baud' also originates) and that was created in the 1870s. https://en.wikipedia.org/wiki/Baudot_code https://en.wikipedia.org/wiki/Baudot_code

    Baudot's (ITA1) was linear, with no concept of lines. Murray's (which evolved into ITA2 with minor changes) added CR LF, since he developed a typewriter-like system.

      Ahhh I see where you've gotten that 1901 date from now: > In 1901, Baudot's code was modified by Donald Murray > The Murray code also introduced what became known as "format effectors" or "control characters" – the CR (Carriage Return) and LF (Line Feed) codes.
