Was Roger Bannister Jewish?

No, the first athlete to run a mile in under 4 minutes, Roger Bannister was not a Jew.

He died 3/3/2018 at age 88. British Prime Minister Theresa May remembered Bannister as a "British sporting icon whose achievements were an inspiration to us all. He will be greatly missed."

Note that Harold Abrahams, the timekeeper who recorded Bannister's first, was a Jew. Wikipedia reports. "Abrahams's father, Isaac, was a Jewish immigrant from Poland, then Congress Poland as part of the Russian Empire. He worked as a financier, and settled in Bedford with his Welsh Jewish wife, Esther Isaacs."

May 6, 1954: "Bannister crossed the line and slumped into the arms of a friend, barely conscious. The chief timekeeper was Harold Abrahams, the 100-meter champion at the 1924 Paris Olympics whose story inspired the film 'Chariots of Fire.' He handed a piece of paper to Norris McWhirter, who announced the time."

In 2011 there was some controversy over Abraham's role as timekeeper at the event.
