In the fall of 2003, EMS West (then known as EMSI) published a newsletter with articles about "The Pioneers of EMS". During EMS Week 2026, we will be reproducing these articles about leaders, legends, and visionaries. Our thanks to Camille Downing for the original articles. Check back throughout the week to learn more about the origins of EMS in our region.
Glenn Cannon’s interest in EMS began when he was a young man in college in Indiana PA. On one fateful night a man drove his car into a tree in front of one of Indiana’s fraternity houses. Glenn was there and went to the man’s aid. He found him not breathing and began mouth-to-mouth resuscitation until the local ambulance arrived. The man’s life was saved thanks to Glenn’s quick action and the work of the Citizen’s Ambulance service personnel, including Jerry Esposito. Glenn knew at that moment that he wanted to be involved in the work of saving lives.
Shortly after, Glenn signed up with Citizens’ working on the ambulance. He was able to take part in the first CPR class ever offered by Dr. Peter Safar. While in college, Glenn became increasingly involved in the field of EMS. He worked closely with Esposito, Safar and Dr. Don Benson on designing the first ambulance that allowed a seat to be placed at the head of the patient for proper airway maintenance during transit. He also helped train the new Freedom House Ambulance personnel who traveled to Indiana County to work in Citizens’ vehicles.
After college, Glenn returned to Pittsburgh and became involved in the creation of the first EMS council in 1972 where he was the deputy direct under Esposito’s leadership. The Allegheny County Council on Emergency Medical and Health Services, later known as EMSI (and now EMS West), developed the process of training and certifying ambulance personnel as EMTs. While with the Council, Glenn was active in helping many communities secure funding through the National Highway Traffic Safety Act to help fund training programs and purchase new vehicles and equipment. It was also during this time that Glenn helped many community colleges and vo-tech schools create EMT training programs, including the first EMT instructor course at Community College of Allegheny County.
In 1975, Glenn was hired by the City of Pittsburgh to plan, develop and implement a new advanced life support ambulance system. He was named the director of the newly formed City of Pittsburgh Bureau of Emergency Medical Services and oversaw the transition from the old “rapid transit” police ambulance service to the highly sophisticated ambulance service staffed by paramedics trained in emergency medicine. The paramedics used radio-equipped “super ambulances” that were categorized as the first mobile intensive care units to operate city-wide out of five stations in the West End, South Hills, North Side, East End and Hill District areas of the city.
Glenn remained active in rescue and other non-traditional ambulance work. He was able to successfully expand the EMS service into the areas of paramedic rescue, river rescue, trench and specialized rescue. He also created the City of Pittsburgh’s first hazardous materials response team, the first in Pennsylvania.
Glenn worked with several of the early physician pioneers to bring about quality prehospital emergency care in the days before the State EMS Act and State paramedic certification. He also worked with Dr. Sol Edelstein and Dr. Nancy Caroline on developing a medical command system that included emergency physicians in the prehospital process of service delivery. The concept grew rapidly into what is todays’ Center for Emergency Medicine and the affiliated emergency residency,
In the mid-1980s, Glenn was named the City of Pittsburgh Public Safety Director where he continued this advocacy for EMS, from training 911 call takers in giving pre-arrival instructions to callers in need, to adding the fire department first responders to the EMS system.
