Incident

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.

Survivors

He was survived by his wife, daughter, father, and sister.
