Roll of Honor
Incident
Patrolman William Ahern died as a result of complications of Spanish Influenza while contracting the flu a week earlier while in the performance of his duties. His patrol duties included checking on the well-being of citizens on his beat who were sick with influenza.
The first case of Spanish Influenza was reported in Boston on August 28, 1918, resulting in more than 4,000 deaths by the end of 1918. Boston Police Officers performed many tasks to help stop the spread of the flu while working an average of 73-98 hours weekly.
Patrolman Ahern was assigned to District 9.
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
Patrolman William F. Ahern died on September 22, 1918 of influenza contracted in the line of duty. He was 33.
He is one of 201 officers honored here, and one of 14 at Boston 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.
