Wilhelm Ostwald, the German chemist and philosopher became interested in chemistry at an early age; as an eleven year old he made his own fireworks. He developed the Ostwald process for the synthesis of nitric acid using a platinum-rhodium catalyst. He proposed that catalysts speed up chemical reactions by lowering the energy of activation. He is one of the founders physical chemistry, the theoretical branch of chemistry which deals with the properties and reactions of ions, atoms and molecules. Curiously enough, although he was one of the most eminent chemists of his time, he did not accept the developement of athomic theory until 1906. He was awarded the 1909
Nobel Prize for Chemistry for his work on catalysis and on the conditions of chemical equilibrium and the velocities of chemical reactions.
