Michael F. O'Brien was born in 1910, in Connecticut. He was employed as a driver before enlisting in the Army Air Corps on September 26, 1940. He served in the 17th Pursuit Squadron, 24th Pursuit Group, as a Private First Class during World War II.

After the fall of Bataan in the hands of the Japanese Army on April 9, 1942, PFC O'Brien was one of the 10,000 to 12,000 Americans who were forced to march over 60 miles under brutal conditions, resulting in 1,000 to 5,000 deaths due to starvation, dehydration, and abuse. Survivors were sent to Camp O'Donnell, where dire conditions, including overcrowding, malnutrition, and disease, caused an additional 1,500 to 2,300 American deaths within weeks. Those who survived faced ongoing hardships, including transfers to other camps and forced labor, where many continued to suffer or die.

PFC O'Brien was among the American soldiers who lost their lives in captivity on May 1, 1942. He is now buried in the Manila American Cemetery and Memorial, Manila, Capital District, National Capital Region, Philippines.
