History
The bag valve mask concept was developed in 1953 by the German engineer, Dr. Holger Hesse, and his partner, Danish anaesthetist Henning Ruben, following their initial work on a suction pump. They named their resuscitator Ambu bag, and then formed their own company, also called Ambu, to manufacture and market it, starting in 1956. This position as first to market has led to the name Ambu becoming a generic trademark, with bag valve masks from any manufacturer being referred to as 'ambu bags'.

Famous quotes containing the word history:
“[Men say:] “Don’t you know that we are your natural protectors?” But what is a woman afraid of on a lonely road after dark? The bears and wolves are all gone; there is nothing to be afraid of now but our natural protectors.”
—Frances A. Griffin, U.S. suffragist. As quoted in History of Woman Suffrage, vol. 4, ch. 19, by Susan B. Anthony and Ida Husted Harper (1902)
“A man will not need to study history to find out what is best for his own culture.”
—Henry David Thoreau (1817–1862)
“There has never been in history another such culture as the Western civilization M a culture which has practiced the belief that the physical and social environment of man is subject to rational manipulation and that history is subject to the will and action of man; whereas central to the traditional cultures of the rivals of Western civilization, those of Africa and Asia, is a belief that it is environment that dominates man.”
—Ishmael Reed (b. 1938)
