[Paul Bert, scientist and politician].

Paul Bert worked with Claude Bernard, one of the leading physiologists of the 19th century. In his laboratory at the Collège de France in Paris, Paul Bert carried out fascinating experiments in particular on respiratory processes, leading him to publish "La pression barométrique" in 1878. In this book are recalled his discovery of oxygen pressure decrease with altitude, divers diseases, the improved safety protocols in hyperbaric conditions, and the first development of gas anaesthetics for surgery. He was the third President of the Société de Biologie. Paul Bert was also a politician with strong convictions. Minister of Education under Gambetta's short term government, he initiated the fight for social equality and secular education and became one of the most prestigious figures of the developing socialist party. He received many distinctions and was given a state funeral.
