Alexander Graham Bell
I started my career as an International Multilingual Telephonist in 1974 with Massey Ferguson.
We operated a switchboard with 20 incoming lines, forwarded the calls to all together 350 colleagues and handled between to the two of us, 1000 calls per day. Incoming and outgoing.
Compared to the modern “switchboards” ours would now be very old fashioned but back in the 70's modern and extremely functional. Not that old fashioned that we had to swing a handle! Although, calling Canada or the Us, we phoned the intercontinental telephonist who connected us to the wanted number.
Gosh, I am getting old…….
