There is an article in the current Oldie magazine about the youngest witness at the Lady Chatterley trial, Bernardine Wall. She was aged 22 and had just come down from Cambridge.
Her father worked at the publishers and was asked to supply a witness to prove that the book wasn't going to corrupt young women.
Bernardine assured the judge that she had read and understood the work, and the judge decided that she had definitely not been corrupted.
There is a lovely photo of her looking fresh-faced and innocent outside the court, wearing her duffle coat.
