Richardson-type spray, United Kingdom, 1866-1884
The Richardson spray was originally used to spray ether to give a local anaesthetic, especially during tooth extraction. The spray is named after its inventor, Benjamin Ward Richardson (1828-1896). He invented the spray in 1866. The air is pushed through using the hand pump, which forces the liquid ether out of the nozzle. Joseph Lister (1827-1912) later adapted this spray for use in antisepsis. It is believed that this is the only surviving spray of this type.
