10 Things You Didn’t Know About Dean O’Banion

Dean O’Banion was Al Capone’s greatest rival in 1920s Chicago — the leader of the North Side Gang who controlled the city’s north side bootlegging territory and ran his criminal empire from behind the counter of a flower shop on North State Street. He was murdered in that same flower shop in November 1924 on the orders of Johnny Torrio, triggering the gang wars that would eventually make Capone famous. Here are ten things most people don’t know about Deanie O’Banion.

1. He had a limp from a childhood accident

As a child O’Banion broke his left leg in two places in an accident. The resulting surgery was imperfect, leaving his left leg approximately one inch shorter than his right. The limp this caused was one of his most immediately recognisable physical characteristics throughout his life.

2. He ran his criminal empire from a flower shop

O’Banion operated Schofield’s Flower Shop on North State Street in Chicago as a legitimate front for his criminal operations. The shop was real and successful — O’Banion was genuinely skilled at floral arrangement and took pride in his work. He was murdered inside the shop in November 1924 when three men entered under the pretext of picking up a funeral arrangement.

3. He was an altar boy before becoming a gangster

O’Banion grew up as a devout Catholic and served as an altar boy at Holy Name Cathedral in Chicago — the same cathedral outside which he would later have enemies killed. His religious upbringing never left him entirely; he reportedly maintained a genuine personal faith throughout his criminal career.

4. He was a gifted safecracker before turning to bootlegging

Before Prohibition made bootlegging the most profitable criminal activity in America, O’Banion built his reputation and his early fortune as a skilled safecracker and burglar. His technical abilities gave him credibility and capital that he parlayed into the bootlegging operations that made him wealthy.

5. He outsmarted Johnny Torrio in a deal that led to his death

The direct cause of O’Banion’s murder was a business deal in which he sold his share of a brewery to Johnny Torrio for $500,000, knowing that federal agents were about to raid it. Torrio was arrested in the raid. Furious at being deliberately set up, Torrio authorised O’Banion’s murder. The killing was carried out by Frankie Yale and two associates.

6. His murder was carried out in front of his own flowers

On November 10, 1924, three men entered Schofield’s Flower Shop. O’Banion greeted them warmly, apparently believing they had come to collect a floral arrangement for a funeral. As he shook hands with one of them, the man gripped his hand and held him while the others shot him six times. He was 32 years old.

7. His funeral was one of the most lavish in Chicago history

O’Banion’s funeral was an extraordinary spectacle — over 10,000 mourners attended, and the floral arrangements filled three trucks. The procession stretched for over a mile through Chicago’s streets. The Catholic Church initially refused to allow a funeral mass given his criminal career, though services were eventually held.

8. His death started the North Side-South Side gang war

O’Banion’s murder triggered a wave of retaliatory violence that would define Chicago’s gangland for years. His lieutenants Hymie Weiss and Bugs Moran launched multiple assassination attempts against Capone and Torrio. Torrio was shot and nearly killed in January 1925, leading him to retire and hand full control to Capone.

9. He genuinely loved flowers

Unlike many criminals who used legitimate businesses purely as fronts, O’Banion had a genuine passion for floristry. He was considered skilled by professional standards and took real pride in his arrangements. Several accounts describe him spending hours on elaborate floral designs between criminal activities.

10. He was never convicted of a serious crime

Despite his extensive criminal career, O’Banion was never convicted of a significant offence. His political connections in Chicago — particularly his relationship with the Republican political machine that controlled the city’s north side — provided him with protection that kept him effectively immune from serious prosecution throughout his career.
