JOHN DALTON

John Dalton
Lived 1766 – 1844.
John Dalton’s Atomic Theory laid the foundations of modern chemistry. In 1801, Dalton gave a series of lectures in Manchester whose contents were published in 1802. In these lectures he presented research he had been carrying out into gases and liquids. This research was groundbreaking, offering great new insights into the nature of gases.

Firstly, Dalton stated correctly that he had no doubt that all gases could be liquefied provided their temperature was sufficiently low and pressure sufficiently high.
