doctors and nurses to render emergency medical care. Hahn recruited two state legislators who wrote the Wedworth-Townsend Paramedic Act of 1970, signed into law by Governor Ronald Reagan on July 15, 1970, despite opposition from doctors, nurses, and attorneys. Paramedic training began the next month at the Freeman Memorial Hospital under Graf's direction. It was the first nationally accredited paramedic training program in the United States. Other communities in the United States were also experimenting with advanced emergency medical care. Pittsburgh's branch of Freedom House paramedics are credited as the first emergency medical technician (EMT) trainees in the United States. Pittsburgh's Peter Safar is referred to as the father of CPR. In 1967, he began training unemployed African-American men in what later became Freedom House Ambulance Service, the first paramedic squadron in the United States. Almost simultaneously, and completely independent from one another, experimental programs began in three U.S. centers; Miami, Florida; Seattle, Washington; and Los Angeles, California. Each was aimed at determining the effectiveness of using firefighters to perform many of these same advanced medical skills in the pre-hospital setting in the civilian world. Many in the senior administration of the fire departments were initially quite opposed to this concept of 'firemen giving needles', and actively resisted and attempted to cancel pilot programs more than once. In Seattle, the Medic One program at Harborview Medical Center and the University of Washington Medical Center, started by Leonard Cobb, M.D., began training firefighters in CPR in 1970. Dr. Eugene Nagel trained city of Miami firefighters as the first U.S. paramedics to use invasive techniques and portable defibrillators with telemetry in 1967. Dr. Jonathan Wasserberger helped actualize the teaching curriculum associated with this innovative training in 1973. Elsewhere, the novel approach to pre-hospital care was also evolving. Portland's Leonard Rose, M.D., in cooperation with Buck Ambulance Service, instituted a cardiac training program and began training other paramedics. Baltimore's R. Adams Cowley, the father of trauma medicine, devised the concept of integrated emergency care, designing the first civilian Medevac helicopter program and campaigning for a statewide EMS system. Other communities that were early participants in the development of paramedicine included Jacksonville, Florida, Pittsburgh, Pennsylvania (in an expanded program), and Seattle, Washington (in an expanded program). In 1972 the first civilian emergency medical helicopter transport service, Flight for Life opened in Denver, Colorado. Emergency medical helicopters were soon put into service elsewhere in the
