Notes: In 1908, Louis Ombredanne, a French surgeon, published a paper detailing his
new inhaler and it’s design (Obredanne, 1908). He listed a number of flaws in
the Clover inhaler that his design surmounted (Thomas, 1975). The Ombredanne,
which was used to administer ether, became very popular, especially in
obstetrics and military anesthesia, and was used up until the second World
War (Plötz, 2001).
