Julius Stieglitz was an American chemist who interpreted the behavior and structure of organic compounds in the light of valence theory and applied the methods of physical chemistry to organic chemistry. He studied molecular rearrangements, catalysis, the theory of chemical indicators, and the structure of organic nitrogen compounds. Stieglitz introduced theories of ionization and chemical equilibrium in Elements of Quantitative Chemical Analysis, 2 vol. (1911–12). His older brother was the photographer Alfred Stieglitz.
