Matthew Bannister on Sidney Poitier, the first black man to win a 'Best Actor' Oscar, known for his powerful performances in ‘In The Heat of The Night’, ‘Lilies of the Field’ and ‘To Sir, With Love’. His co-star in that film - Lulu - pays tribute. E.O.Wilson, the American biologist and champion of biodiversity who some have compared to Charles Darwin. Sarah Weddington, the lawyer who argued the landmark case of Roe v Wade before the US Supreme Court. The case, which is being challenged now, established the constitutional right for women to have abortions. Assunta ‘Pupetta’ Maresca, the Italian mafia boss who served a prison sentence for shooting dead the man who killed her husband.
