Did Robert Bolt invent the phrase A Man for All Seasons and if not where did it come from?

Khawla I had already received the correct answer to my question which is that Robert Whittinton created the phrase and therefore Robert Bolt's title, and I have made use of this piece of intelligence already.  If you scroll through the replies above yours you will see that the teacher Sagetrieb answered me already.

But thank you for offering the copy.
