The “Club of Mainz” for Improved Emergency and Disaster Medicine Worldwide was conceived in 1973 and founded in 1976 by about 10 reanimatologists under the leadership of the late Rudolf Frey (Crit Care Med 6:389, 1978). Its objectives are: “(1) to foster optimal resuscitation and life support methodologies worldwide; (2) to concern itself with a range from everyday emergencies to mass disasters, with appropriate consideration for differences in populations, available resources and other factors; and (3) to informally pursue the objectives by combining the resources of scientific, social and related information and experiences, together with international communication and collaboration.”
