John Dalton was born on September 6, 1766 and died on July 27, 1844. Although he was a teacher, chemist, and physicist; Dalton had set his priorities on teaching. In 1833, Dalton was awarded an annual civil pension. This was given to him after many years after lecturing and teaching.
John Dalton recorded more than 200,000 atmospheric observations throughout his life. Later on these observations led to his study of gases. Dalton wrote a book on meteorology which included his explanation on how the aurora borealis is a magnetic phenomenon. After this he published the generalization that all gases initially at the same temperature expand equally on going to the same higher temperature, which he was the first to do.
