Einstein fled Europe after Hitler came to power in 1933 - hiding out on a farm in Roughton, near Cromer, for three weeks before emigrating to the US.

He was there at the invitation of an MP he had previously met called Oliver Locker-Lampson.

During his stay Einstein had an armed guard and it was thought his life could have been in danger, so hated was he by the Nazis.

Einstein’s letter to Sir William  - who at the time was provost of Oriel College, Oxford - voices concern for a German philosopher, Professor Julius Stenzel.

The top line of the letter reads: Cromer, 1 X [October], 33.
