Benito Mussolini was the leader of the National Fascist Party and he became the Prime Minister of the country in the year 1922 and ruled till the year 1943 when he was ousted. Mussolini was born on 29th of July in the year 1883 and died on 28th of April in the year 1945. For a few years he followed the constitution but later he assumed the role of a dictator.
I found that it's most likely Patrick Moore. He was the presenter of the BBC show "The Sky at Night" for 50+ years and was also an environmental activist. He only missed the one episode of "The Sky at Night" because of food poisoning.
