He is best known for developing the atomic theory, which explains how matter is made up of tiny particles called atoms. Dalton also discovered the law of partial pressures, which describes how gases behave when mixed together. Additionally, he was the first person to describe red-green color blindness, a condition where some people have difficulty distinguishing between red and green colors.
