Alice Ball didn’t get credit for her groundbreaking leprosy treatment because she died at 24 before she could publish her findings, and her university supervisor then published her work under his own name. Her early death, combined with the racial and gender dynamics of 1916 Hawaii, made it easy for her contribution to be erased for decades.
What Alice Ball Actually Discovered
In the early 1900s, the only known treatment for leprosy (Hansen’s disease) was chaulmoogra oil, extracted from the seeds of a tropical tree. The problem was that the oil was nearly unusable. It was too thick and sticky to inject, caused painful skin reactions when applied topically, and made patients vomit when swallowed. Doctors at Kalihi Hospital in Hawaii, where leprosy patients were quarantined and separated from their families, were desperate for a better delivery method.
Ball, a young chemist and the first woman to earn a master’s degree from the University of Hawaii, took on the challenge. She identified the oil’s two main active components, chaulmoogric acid and hydnocarpic acid, then isolated the specific fatty acids within each one. Her key breakthrough was chemically converting those fatty acids into a form called ethyl esters, which dissolved in water and could be safely injected. The treatment worked remarkably well. By 1918, 78 patients at Kalihi Hospital who received injections based on her method were free of lesions and discharged to reunite with their families.
Her Death Left Her Work Unprotected
Ball died on December 31, 1916, just as her treatment was beginning to show results. She was 24 years old and had not yet published her research. The circumstances of her death remain murky and possibly deliberately obscured. Her death certificate was altered to list tuberculosis as the cause, but a newspaper article published in 1917 reported that she died from chlorine poisoning suffered while demonstrating the use of gas masks. A photograph taken at her graduation, just one year before her death, shows a healthy young woman with none of the visible wasting that chronic tuberculosis would cause.
Whatever killed her, the timing was devastating for her legacy. In science, credit flows to whoever publishes first. Ball had completed the chemical work but hadn’t had the chance to put her name on it in a journal.
How Arthur Dean Took Credit
After Ball’s death, Arthur L. Dean, the president of the University of Hawaii and her department chair, continued her research. He published the findings without crediting Ball as the originator of the method. Dean presented the technique as his own contribution and even named it the “Dean Method.” Because he held institutional power and Ball was no longer alive to object, the appropriation went largely unchallenged at the time.
There was one notable exception. Dr. Harry T. Hollmann, the physician at Kalihi Hospital who had originally asked Ball to work on chaulmoogra oil, publicly objected. In a 1922 publication, Hollmann attempted to set the record straight by crediting Ball for the chemical process. But Hollmann was a physician, not a chemist with university authority, and his correction didn’t gain traction. Dean’s version of events became the accepted history.
Why Being a Black Woman in 1916 Mattered
Ball’s erasure wasn’t purely about timing. She was a Black woman working in academia at a time when both her race and her gender placed her at the bottom of institutional power structures. She had no tenure, no senior allies positioned to defend her legacy, and no network of peers who would have flagged the appropriation as scandalous. A white male professor in the same era, even one who died young, would have been far more likely to have colleagues advocate for proper attribution.
The alteration of her death certificate adds another layer to the story. Researchers have noted that the cause of death may have been deliberately concealed, possibly because a lab accident involving chlorine gas could have reflected poorly on the university. If the institution had reason to minimize her presence in its records, that same impulse would have made it easier to minimize her scientific contributions too.
How Her Credit Was Restored
Ball’s story remained largely forgotten for more than half a century. It wasn’t until researchers began digging through University of Hawaii archives decades later that the full picture of her work resurfaced. The evidence was clear: the chemical method that treated thousands of leprosy patients worldwide before antibiotics replaced it in the 1940s was Ball’s invention, not Dean’s.
Recognition came slowly but eventually in significant forms. On February 29, 2000, the Governor of Hawaii declared “Alice Ball Day.” That same day, the University of Hawaii mounted a bronze plaque at the base of the lone chaulmoogra tree on its campus, honoring its first woman graduate and pioneering chemist. In January 2007, the university’s Board of Regents awarded Ball its highest honor, the Regents Medal of Distinction, posthumously conferred more than 90 years after her death.
The treatment she developed is now properly known as the “Ball Method.” It remained the best available treatment for leprosy for over two decades until sulfone antibiotics emerged in the 1940s. During that time, it gave hundreds of quarantined patients their lives back, a legacy that went uncredited for most of the 20th century because a young Black woman died before she could put her name on her own work, and the man above her in the hierarchy put his name there instead.
