Max Trautz (19 March 1880 – 19 August 1960) was a German chemist. He was very productive with over 190 scientific publications especially in the field of chemical kinetics. He was the first to investigate the activation energy of molecules by connecting Max Planck's new results concerning light with observations in chemistry.
He is also known as the founder of collision theory together with the British scientist William Lewis. While Trautz published his work in 1916, Lewis published it in 1918. However, they were unaware of each other's work due to World War I.
