Edward Michael Hennessey

Patrolman Edward Hennessey died as a result of contracting influenza while in the performance of his assigned duties of enforcing health orders and operating ambulances during the Influenza Pandemic in Dayton.

Dayton City Police Officers had been ordered to close saloons that violated health orders, man ambulances, keep crowds from gathering, and remove corpses. More than 700 citizens died from the Spanish Influenza between October 1918 and January 1919. As a result of stopping the spread of the flu and maintaining order in the city of Dayton, many members of the Dayton City Police Department became ill with the flu, and six officers died.

Patrolman Hennessey served with the Dayton Police Department for almost six and a half years. He was survived by his wife, daughter, father, and sister.


Effects of the 1918-1920 Influenza Pandemic on Law Enforcement

Also 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.
