dalton  (dôl'tən) Pronunciation Key
See atomic mass unit. |
| Dalton, John 1766-1844.
British chemist whose pioneering work on the properties of the atmosphere and gases led him to formulate the atomic theory. Dalton's theory stipulates that all matter is made up of combinations of atoms, the atoms of each element being identical. These atoms can be neither created nor destroyed, but chemical reactions take place through their rearrangement. |

Dalton
city, seat (1851) of Whitfield county, northwestern Georgia, U.S., encircled by the Cohutta Mountains. Although founded in 1837 as Cross Plains, it was renamed, probably, for the mother of Edward White (head of the syndicate that bought the townsite), whose maiden name was Dalton. It developed as a shipping point for copper mined nearby. Several American Civil War battles were fought in the area, and in 1863-64 Dalton served as the headquarters of Confederate General Joseph E. Johnston and the Army of Tennessee.
