Butch O’Hare: Chicago’s War Hero with Ties to Al Capone

Most people have no idea who O’Hare Airport is named after.

Millions pass through Chicago’s O’Hare International Airport each year without ever wondering where the name comes from. It’s easy to assume it honors an aviation pioneer or political figure. But the truth is far more dramatic. The airport is named for Edward “Butch” O’Hare, a World War II flying ace. And his story begins not in the skies—but in the shadowy world of organized crime, through his father’s close ties to none other than Al Capone.

The Father’s Double Life

Butch’s father, Edward “Easy Eddie” O’Hare, was a high-powered attorney and a trusted legal advisor to Al Capone. More than just a mob lawyer, Easy Eddie helped manage Capone’s illegal business empire, including his lucrative racetracks and slot machine operations. He lived lavishly, enjoying wealth that came directly from his work for the most feared gangster in America. But somewhere along the line, his conscience—or perhaps his desire to leave a better legacy for his son—began to stir.

In 1930, Easy Eddie quietly began cooperating with federal investigators. He provided the IRS with internal financial records and key details that helped convict Capone of tax evasion. He even tipped off authorities about a scheme to rig the jury, leading to a last-minute jury swap that helped seal the verdict. Though the trial ended in 1931, Eddie lived under constant threat for years. Then, on November 8, 1939—just days before Capone was due to be released from Alcatraz—Easy Eddie was gunned down while driving through Cicero. No one was ever arrested, but the message was clear.

The Son’s Heroism in the Skies

Butch O’Hare had grown up surrounded by privilege, but he chose a path of duty. After graduating from the U.S. Naval Academy and earning his wings, he found himself on the USS Lexington in early 1942. On February 20 of that year, during a mission in the South Pacific, O’Hare became a legend. With his squadron out of range and enemy bombers closing in, Butch flew solo into a group of nine Japanese planes, armed with only enough ammunition for a short burst of combat.

Displaying remarkable skill and fearlessness, he shot down five enemy bombers and damaged a sixth—saving the carrier and hundreds of lives. He returned to the Lexington with just a few bullets left. For his actions, he received the Medal of Honor, becoming the Navy’s first flying ace of World War II. Sadly, his story didn’t end there. In 1943, Butch was killed during a night mission over the Gilbert Islands. His body was never recovered.

From Orchard Field to O’Hare

After the war, Chicago sought to honor Butch’s sacrifice and heroism. Orchard Place Airport, a former military airfield northwest of the city, was being developed into a major commercial hub. In 1949, it was officially renamed O’Hare International Airport. Though the old airport code “ORD” stuck, the new name gave the city a chance to honor a local son whose courage reflected the best of American service.

Today, the airport features more than just a name. In Terminal 2, near the security checkpoint, visitors can see a full exhibit dedicated to Butch O’Hare. The centerpiece is a restored Grumman F4F Wildcat fighter, like the one he flew on his famous mission. The display includes photos, military honors, and biographical panels. A plaque and accompanying exhibits tell the story of the man behind the name. For more details on where to find the display, visit: Butch O’Hare Exhibit at O’Hare International Airport.

The story of Easy Eddie and Butch O’Hare is filled with contradictions: crime and honor, betrayal and redemption, legacy and loss. But Chicago chose to remember the son—the Medal of Honor recipient who gave his life for his country—and in doing so, created a lasting symbol of service. O’Hare International Airport may be a global crossroads, but at its heart is the story of one brave young man and the complicated father who made his heroism possible.
