John Dalton
1766–1844
A quiet Quaker schoolteacher became one of the key figures in modern science by turning careful observation into a powerful new way of understanding matter. Best known for laying the groundwork for atomic theory, he also made early studies of color blindness and kept an intense interest in weather throughout his life.

About the author
Born in Eaglesfield, Cumberland, in 1766, John Dalton grew up in a Quaker family and began teaching while still very young. He later built his career in Manchester, where he worked as a teacher, lecturer, and researcher, earning a reputation for patient measurement and plain, practical thinking.
Dalton is remembered above all for helping establish modern atomic theory. His work on the way elements combine in fixed proportions gave chemistry a clearer framework, and his book A New System of Chemical Philosophy became a landmark in the field. He also studied gases and meteorology in detail, showing how wide his scientific curiosity really was.
Another lasting part of his story is his investigation of color blindness, a condition he described from personal experience. Though some parts of his atomic model were later revised, his influence on chemistry and physics was enormous, and his name remains closely tied to one of science's biggest shifts in understanding matter.
