Priestley was a Unitarian minister and he never studied science formally. Under the influence of Benjamin Franklin, Priestley carried out research on electricity (1769). In 1772 he isolated a number of gases, such as nitrous oxide and in 1774 he isolated a new gas "dephlogisticated air" (oxygen) and studied the properties of this new gas. Priestley also recognized the fact that plants were influenced by light (photosynthesis).
