Heinz Wolff: Scientist and Great Egg Race host remembered
Laurence Wolff says his father Heinz, the famed science professor and BBC presenter, wished to "inspire young people" by using science to "entertain as well as educate".
He added: "The person that people saw when they met him was the person we knew at home. His sense of humour, his curiosity, his enthusiasm. That was our father."
