Incident

Police Officer John Diamond died as a result of complications of influenza while in the performance of his assigned duties during the Influenza Pandemic.

Due to the devastation of the Influenza Epidemic, Philadelphia Police districts were used as makeshift hospitals. Police officers were ordered to fill and deliver prescriptions, act as pallbearers of victims, placard homes, collect bodies of victims out of their homes, assist doctors and health officers, and make sure establishments were closed and following guidelines to stop the spread of the flu.

Police Officer Diamond served with the Philadelphia Police Department for ten and a half years and was assigned to the 16th Police District.

Effects of the 1918-1920 Influenza Pandemic on Law EnforcementAlso known as "Spanish Flu" or "LaGrippe," the Influenza Pandemic of 1918 to early 1920, infected an estimated 500 million people worldwide—about one-third of the planet’s population—and killed approximately 675,000 Americans. The effect of the influenza epidemic in the United States was so dire that the average life span in the U.S. fell by twelve years. The four waves of the flu began in March 1918 and ended in April 1920. Many officers contracted this virus due to the requirements of their job. The names of every officer who died in the line of duty from the Influenza Pandemic will likely never be known. Still, ODMP researchers continue to uncover new cases as part of our mission never to forget the fallen.

The 1918 Influenza Pandemic

Police Officer John Diamond died on October 15, 1918 of influenza contracted in the line of duty. He was 41.

He is one of 201 officers honored here, and one of 45 at Philadelphia Police Department.

The influenza pandemic of 1918 killed more people worldwide than the war that preceded it. Police officers worked it without vaccines, without antibiotics, and often without masks, enforcing quarantines, transporting the sick, and standing posts in cities where the dead outpaced the undertakers.

They caught it doing the job. There was no treatment to give them.

Survivors

He was survived by his wife and six children.
