John R Leigh, born in Bolton, Lancashire, and educated in Cambridge, was musical, mathematical, scientific and literary. At school in the 1930s, his headmaster told him there would be no more wars and no need for more scientists. His life then ranged first from languages teacher, radar technician and RAF flight lieutenant in WWII, to marriage with a talented and literary American wife. After the war, John changed career to retrain in engineering—for a married man, a brave decision. Over the years, the keen theatre-going couple saw many diverse plays. Convinced that he had found an original approach to seeing Shakespearean dramas, he spent happy years describing and refining his thoughts: what ideas, prejudices and religious beliefs would surface in the minds of Shakespeare’s own audience, the groundlings and nobles? In our day, we cannot help but react with our own beliefs and social customs; yet in Globe Theatre, how would people have responded to seeing a ghost in the early sixteenth century? Rather differently than nowadays, John thought. (Hamlet studies form the greater part of his collected work.) Suppose you were seeing Hamlet for the first time: hence the title ‘The Naïve Shakespearean’.
