Metal carbolic steam spray with case. Made in Europe between 1872 and 1900. Joseph Lister (1827-1912) invented the carbolic acid spray as he believed most infection-causing germs were in the air. The steam spray covered everyone and everything in the operating room or hospital ward with a vapor of carbolic acid or phenol intended to create an antiseptic environment. The steam spray meant that an assistant was not required to work a cumbersome pump. Lister eventually abandoned the spray in 1887 as he found that germs carried on fingers, dressings, and the skin of the patient were more important. The spray had its own disadvantages as inhaling carbolic acid is dangerous.
