- Joseph Leonard Goldstein born 1940: cholesterol metabolism and its regulation; Nobel Prize (medicine), 1985.
- George Herbert Hitchings born 1905: pharmaceutical chemistry; Nobel Prize (medicine), 1988.
- Eugene Jules Houdry born 1892: commercial catalytic cracking of petroleum for gasoline production (Houdry process, first patent application in France; US patent 1,837,963) and catalytic cleaning of automobile exhaust.
- Paul-Émile Lecoq de Boisbaudran born 1838: discovered gallium (Ga, element 31), dysprosium (Dy, 66), and samarium (Sm, 62).
- William Albert Noyes, Jr., born 1898: editor of Journal of the American Chemical Society, 1950-1962.
- Joseph Priestley ignited a mixture of "inflammable air" (hydrogen) and common air, 1781, and noted that the explosion was not as powerful as can be obtained from gunpowder. He failed to recognize (as Cavendish, Lavoisier, and Watt did soon afterwards) that the two gases combine to form water.

- Samuel Cox Hooker [scroll down] born 1864: sugar chemistry
- Antoine Lavoisier claimed the right to the discovery of oxygen (O, element 8), arguing that he and Joseph Priestley discovered the same facts, but that he recognized the role of oxygen in combustion while Priestley explained it in terms of phlogiston theory, 1776. (This claim is treated fictionally in the play Oxygen by Carl Djerassi and Roald Hoffmann.)
- Ines Hochmuth Mandl born 1917: biochemical basis of pulmonary emphysema; medicinal uses of collagenases, elastases, and their inhibitors; Garvan Medal, 1982
