In 1899, a Dr. Schneiderlin recommended the use of hyoscine and morphine for surgical anaesthesia and it started to be used for purpose, sporadically.[3][4] The use of this combination to ease birth, was first proposed by Richard von Steinbuchel in 1902 then was picked up and further developed by Carl Gauss in Freiburg, Germany starting in 1903.[5] The method came to be known as "Dämmerschlaf" ("twilight sleep") or the "Freiburg method".[3][5] It spread rather slowly, and different clinics experimented with different dosages and ingredients; in 1915 The Canadian Medical Association Journal reported that "the method [was] really still in a state of development".[3]
