RIP Sir Roger Bannister, First to Break 4-Min Mile

• Bannister set world record by running mile in 3min 59.4 secs
• Former athlete died in his sleep [age 88] surrounded by family
…at the Iffley Road sports ground in Oxford on 6 May 1954 …Bannister, then a 25-year-old medical student, had broken a mark many felt was impossible. His record stood for just 46 days but his place in history was instantly assured.…

I was but a toddler when this happened, but even when I was grade-school age, this was still held up as (a) example of humans achieving what "couldn't be done," and (b) once someone broke the barrier, somehow, it was exceeded repeatedly.
