American physicist Arthur Jeffrey Dempster died #OTD in 1950.
His most significant achievement was the invention of the first mass spectrometer capable of separating ions according to their mass-to-charge ratio. This device allowed for the precise measurement of atomic and molecular masses. His work laid the foundation for the field of mass spectrometry, which has since become an indispensable tool in chemistry, physics, biology, and environmental science.
