He was wrong, and his incorrect theory led many early chemists to misunderstand the significance of some of their greatest discoveries. Chemistry - Periodic Table - Learning Points. Johann Becher suggested that all flammable substances contained phlogiston. The theory of phlogiston prevented chemists from realising the true nature of elements. Henry Cavendish didn't realise he had discovered hydrogen. Joseph Priestley didn't realise he had discovered oxygen. A Twig Context Film. Reinforce and extend the learning required by the curriculum. Twig’s context films show abstract concepts in action in the real world.\n
