Harry Greb: Record, Best Fights, & Boxing Career Breakdown

Harry Greb was one of the most relentless and accomplished fighters in boxing history. Known as the “Pittsburgh Windmill,” Greb fought at a pace few opponents could match, competing against elite middleweights, light heavyweights and even heavyweights during an extraordinarily active career.

He is perhaps best remembered today as the only fighter to officially defeat Gene Tunney. But Greb’s résumé extends far beyond Tunney. He fought many of the leading fighters of his generation, captured the world middleweight championship and continued competing at the highest level despite severe damage to his eyesight.

Greb competed in an era when no-decision bouts were common, making his career record more complicated than those of modern fighters. Depending on how newspaper decisions are incorporated, historical databases can show significantly different totals.

What is not disputed is the extraordinary scale of his career. Greb competed nearly 300 times while facing an unusually deep collection of elite opponents.

Career Snapshot

Greb turned professional in 1913 and quickly developed a reputation for extraordinary activity.

Rather than building his career within a single weight division, he regularly faced larger opponents. Greb competed against middleweights, light heavyweights and heavyweights, frequently giving away significant size.

His style made him exceptionally difficult to control. Greb attacked from unusual angles, threw punches in volume and maintained a pace that could overwhelm technically skilled opponents.

One of the defining moments of his career came against Gene Tunney in 1922.

Tunney would eventually become heavyweight champion and retire with only one official professional defeat. That defeat came against Greb.

The two ultimately fought five times, creating one of the most important rivalries of the 1920s.

Greb later captured the world middleweight championship from Johnny Wilson in 1923 and successfully defended the title multiple times before losing it to Tiger Flowers in 1926.

He died later that year at only 32 years old.

Best Fights

Best Win: Gene Tunney I

Greb’s first fight against Gene Tunney in 1922 produced the defining victory of his career.

Tunney entered as one of boxing’s rising light heavyweight talents, but Greb’s relentless pressure overwhelmed him.

The fight was exceptionally punishing. Tunney suffered significant facial damage as Greb maintained his trademark pace throughout the contest.

Greb won the decision and handed Tunney what would remain the only official defeat of Tunney’s professional career.

That fact became even more impressive as Tunney continued developing, eventually defeating Jack Dempsey twice and becoming world heavyweight champion.

Best Fight: Mickey Walker

Greb met fellow Hall of Famer Mickey Walker in 1925 in a highly anticipated middleweight championship fight.

Walker was a powerful, aggressive fighter who had already established himself as one of the outstanding boxers of his generation.

Greb nevertheless controlled much of the fight with his activity and movement, winning the decision after 15 rounds.

The victory stands among the strongest wins of Greb’s championship career and demonstrated that even late in his career, he could defeat elite opposition.

Most Controversial Fight: Gene Tunney II

Greb and Tunney met for the second time in 1923.

Tunney received the official decision, avenging his previous defeat, but contemporary ringside opinion was divided over the result.

The disputed decision became part of the larger Greb-Tunney rivalry, which eventually stretched across five fights.

Tunney continued improving throughout the series, while Greb remained one of the most difficult opponents of his career.

Most Underrated Performance: Tommy Loughran

Tommy Loughran would eventually become world light heavyweight champion and one of the finest technical boxers of his era.

Greb faced him repeatedly before Loughran reached his championship peak.

Their fights demonstrated Greb’s ability to disrupt a sophisticated boxer through pressure, activity and unpredictable movement.

Loughran became another future Hall of Fame-level opponent on a résumé filled with elite fighters.

Boxing Style & Skill Breakdown

Harry Greb’s fighting style was built around activity.

His nickname, the “Pittsburgh Windmill,” reflected the relentless volume and unconventional movement that made him so difficult to fight.

Greb rarely allowed opponents to establish a comfortable rhythm.

Strengths

Relentless Pace

Greb’s greatest weapon was his work rate.

He could maintain sustained offensive pressure while forcing opponents to defend and react for extended periods.

Unpredictable Movement

Greb attacked from unusual positions and angles. His movements could appear awkward, but they made his attacks difficult to anticipate.

Conditioning

Maintaining Greb’s style required extraordinary endurance.

His conditioning allowed him to continue attacking deep into long fights without dramatically reducing his output.

Adaptability

Greb successfully fought opponents across several weight classes.

He could pressure technical boxers, fight physically with larger opponents and adjust his approach depending on the opponent.

Toughness

Greb competed through injuries and physical disadvantages that would have ended many fighters’ careers.

His ability to function despite serious problems with his eyesight became one of the defining elements of his later career.

Weaknesses

Greb’s aggressive style was not built around textbook defensive positioning.

His willingness to attack continuously could expose him to counters, and his unconventional technique sometimes sacrificed defensive structure for offensive activity.

As Gene Tunney developed across their rivalry, he became increasingly capable of dealing with Greb’s pressure through movement, positioning and disciplined boxing.

Style Matchups

Greb was particularly dangerous against fighters who required time and space to establish their offense.

His constant activity could destroy that rhythm.

Technically disciplined fighters with excellent movement presented a more complicated challenge. Tunney’s progression across their five fights demonstrated how a sufficiently adaptable boxer could eventually become better equipped to deal with Greb’s pressure.

Physical Attributes & Ring IQ

At approximately 5’8″ (173 cm) with a 71″ (180 cm) reach, Greb frequently fought opponents who were naturally larger than he was.

Size was rarely the foundation of his success.

Instead, Greb used conditioning, activity and unpredictable movement to prevent larger opponents from comfortably exploiting their physical advantages.

His willingness to compete beyond the middleweight division became one of the most remarkable characteristics of his career.

Harry Greb vs. Gene Tunney

Greb and Gene Tunney fought five times between 1922 and 1925.

Greb Tunney I

Greb defeated Tunney in 1922, handing him the only official loss of his professional career.

Greb Tunney II

Tunney received the decision in their 1923 rematch, although the result generated considerable disagreement among contemporary observers.

Greb Tunney III, IV, & V

Tunney continued developing technically as the rivalry progressed and received the official verdicts in their remaining meetings, including a draw appearing in the historical series depending on the accounting of their contests.

The rivalry became a significant part of both men’s careers.

For Greb, beating the future heavyweight champion represented one of his greatest accomplishments.

For Tunney, learning how to deal with Greb’s relentless style became an important part of his development into the fighter who would eventually defeat Jack Dempsey.

Harry Greb and Jack Dempsey

Harry Greb and Jack Dempsey never fought in an official professional bout.

Their names are nevertheless frequently connected because Greb was an elite fighter operating across middleweight, light heavyweight and heavyweight competition during Dempsey’s championship era.

Stories also exist about Greb working with Dempsey in sparring.

Those accounts should not be confused with an official Greb-Dempsey fight. There is no professional bout between the two men on their records.

The matchup remains one of boxing history’s notable “what if” fights from the 1920s.

Harry Greb’s Eye

One of the most remarkable aspects of Greb’s career was the deterioration of his eyesight.

Greb suffered serious damage to his right eye during his career and eventually lost vision in it.

Despite the injury, he continued fighting elite opponents.

The full chronology of when Greb completely lost sight in the eye has been debated by boxing historians, but the underlying fact is well established: Greb competed for a significant portion of his later career with severely compromised vision.

That makes the level of opposition he continued to face even more extraordinary.

Why Is There So Little Harry Greb Fight Footage?

Greb competed during an era when fight films were far less consistently preserved than they would be in later decades.

No complete surviving film of an actual Harry Greb professional fight is known to be publicly available today.

That does not mean Greb was never filmed.

Footage survives showing Greb outside normal professional fight competition, including training material. Historical records also indicate that at least some of his actual fights were filmed.

Those fight films have either been lost, destroyed, deteriorated or have yet to surface.

The absence of surviving fight footage has contributed to Greb’s unusual position in boxing history: he possesses one of the sport’s most celebrated résumés, yet modern fans cannot evaluate his prime performances on film the way they can fighters from later generations.

Legacy & Historical Ranking

Harry Greb’s reputation rests heavily on the depth and scale of his competition.

He fought an extraordinary number of bouts while repeatedly facing elite fighters across multiple divisions.

Gene Tunney, Mickey Walker, Tommy Loughran, Maxie Rosenbloom, Tiger Flowers, Battling Levinsky and Jack Dillon were among the prominent names connected to his career.

Most significantly, Greb remains the only fighter officially credited with defeating Tunney.

His lack of surviving fight footage makes direct visual comparison with later fighters difficult. Modern audiences largely have to evaluate Greb through contemporary reports, historical records and the accomplishments of the opponents he faced.

Those records explain why his name continues to appear prominently in discussions of boxing’s early greats nearly a century after his death.

Record Breakdown

Harry Greb’s professional record requires historical context.

Many fights during his era were officially recorded as no-decision bouts because local rules prohibited an official ringside verdict unless the contest ended by knockout.

Newspapers nevertheless frequently published their own decisions.

Modern boxing historians and record databases therefore sometimes incorporate those newspaper decisions when reconstructing fighters’ careers.

As a result, Greb’s record may appear differently depending on the source and accounting method being used.

Rather than relying solely on a single win-loss total, his career is better understood through the enormous number of bouts he fought and the quality of opposition he faced.

Notable Rivalries

Gene Tunney

Their five-fight series is Greb’s most historically significant rivalry. Greb gave Tunney his only official professional defeat before Tunney eventually took control of the series.

Tiger Flowers

Flowers defeated Greb twice in 1926, including the fight that ended Greb’s reign as world middleweight champion.

Tommy Loughran

Greb fought Loughran multiple times during Loughran’s development into one of the leading light heavyweights of the era.
