Roll of Honor
Incident
Police Officer Martin Clark contracted Spanish Influenza while assigned to his duties at the Liberty Loans Parade on September 28, 1918. Officer Clark became ill the next day and was taken to Saint Joseph Hospital where he died of complications two weeks later.
Cities throughout the country were hosting parades to promote government bonds and raise money for wartime efforts. The city of Philadelphia was in charge of raising $259 million during the fall of 1918. The Philadephia Liberty Bond Parade was projected to have 10,000 attendees, but more than 200,000 people attended.
On September 19, 1918, sailors at the Philadelphia Navy Yard who returned from the war in Europe were struck with influenza. The day following the parade, more than 100 cases of flu were present in the city of Philadelphia. By October 1, every bed in Philadelphia's 31 hospitals was filled. On October 3, the city of Philadelphia shut down. One week later, 4,500 citizens were declared dead of the Spanish flu, and 47,000 people were infected.
Police Officer Clark served with the Philadelphia Police Department for 15 years and was assigned to the 4th 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 Martin R. Clark died on October 13, 1918 of influenza contracted in the line of duty. He was 44.
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 two sons.
