> It took until 1975 for someone to figure this out
Sketched out in 1874 as a concept by Jevons, firmed up (sans implementation) in 1970, first implemented in 1973 (classified for nigh on 30 years by the UK Govt).
First public example (of a different schema) was 1976.
Other examples worked out in 1974, not published until 1978. etc.
I have no great quibble here, 1975 is a good approximate ballpark figure but I wasn't sure which scheme you had in mind as it's almost the only year in the 1970s that nothing particularly significant happened in public key crypto.
