Neglected No Extra: Alice Ball, Chemist Who Created a Therapy for Leprosy


This text is a part of Neglected, a sequence of obituaries about outstanding folks whose deaths, starting in 1851, went unreported in The Occasions.

On New 12 months’s Day in 1922, a scientific paper in an obscure medical journal described a drug that may assist revolutionize the remedy of leprosy in Hawaii and past. It might additionally give belated credit score to the drug’s developer.

The report, by Harry Hollmann, extolled the therapeutic potential of chaulmoogra oil, initially a folks treatment for leprosy with historical roots in India and China. For hundreds of years, chaulmoogra tree oil had been referred to as a nasty drugs — foul-tasting and stomach-wrenching, it was so vile that some folks refused to take it. However in his paper, Hollmann named the method that remodeled chaulmoogra right into a Twentieth-century leprosy drugs: the Ball Technique, a easy injection that freed dozens of individuals within the Territory of Hawaii from draconian quarantines. The Ball Technique wasn’t a treatment, however it was as shut to 1 as anyone acquired by 1922.

It was named for Alice Ball, a Black chemist who had developed her system in 1915 when she was 23. She had just lately earned a grasp’s in chemistry and was an teacher on the Faculty of Hawaii (now the College of Hawaii) in Honolulu.

Her methodology turned essentially the most extensively used remedy for leprosy within the pre-antibiotic years of the Twenties and ’30s. Modified chaulmoogra oil, based mostly on the Ball Technique, was distributed worldwide and helped free numerous folks from remoted leper colonies. (The injections would finally fall out of favor with the emergence within the late Nineteen Thirties of sulfa medication, the primary class of antibiotics ever developed.) ‌‌

For roughly 20 years, when the Ball Technique was in vogue, few outdoors the tiny Faculty of Hawaii knew {that a} Black girl had developed it, and barely anybody even referred to it because the Ball Technique. Ball died all of the sudden earlier than she may publish her findings. The analysis she left behind on the faculty was honest recreation for individuals who needed to say her breakthrough as their very own.

“Two males did steal her work and didn’t give her any credit score for her contributions — particularly Arthur Dean, who was president of the Faculty of Hawaii, and Richard Wrenshall, a chemistry professor,” Sibrina Collins, govt director of the Marburger STEM Middle at Lawrence Technological College in Michigan, mentioned in a phone interview.

“They revealed a 1920 paper within the Journal of the American Chemical Society and a second 1922 paper” — in Public Well being Studies — “along with her analysis and failed to say her or checklist her contributions,” added Collins, who holds a doctorate in chemistry and has written extensively about Black scientists, together with Ball.

Arthur Dean, a chemist with a Ph.D. from Yale, capitalized on Ball’s analysis by naming it after himself: the Dean Technique. He additionally produced the medicine in massive portions on the Faculty of Hawaii, transport it domestically and overseas. The chaulmoogra enterprise was his first and solely foray into pharmaceutical chemistry.

It might take greater than half a century for Ball to obtain credit score for her work. Hollmann, a doctor and bacteriologist, was her first public advocate.

In 1915, Hollmann was the performing assistant surgeon at Hawaii’s Leprosy Investigation Station when he was given a replica of Ball’s grasp’s thesis, a 44-page evaluation of the kava plant’s chemical properties. He contacted Ball and requested if she would deal with one other sophisticated puzzle: chaulmoogra’s mystifying chemistry.

The storied oil is produced by seeds of Hydnocarpus wightianus, a tree native to Asia. When folks took it orally, they turned nauseated. As an ointment, its viscosity hindered absorption. Injecting the unprocessed oil induced it to ulcerate the pores and skin, additional disfiguring these whose pores and skin was already broken by leprosy.

Ball accepted Hollmann’s problem and, in a sequence of arduous however elegant steps, cracked the complicated chemical code hid within the oil. She first recognized its two most important elements: chaulmoogric and hydnocarpic acids. From every she remoted the energetic constituents, a number of fatty acids. She chemically modified the fatty acids by changing them to ethyl esters, a kind that was water soluble and could possibly be injected with out the hurt finished by the uncooked oil.

Hollmann examined her remedy on his sufferers, and he noticed that the ethyl esters have been bactericidal, able to killing micro organism. He acknowledged her innovation, coining the time period “the Ball Technique,” in his 1922 paper, revealed within the journal Archives of Dermatology and Syphilology.

“After quite a lot of experimental work,” Hollmann wrote, “Miss Ball solved the issue for me.”

“Eighty-four sufferers who’ve been on the remedy for intervals starting from 4 years to a few months have develop into bacteriologically unfavorable and free from all lesions of the illness and have been discharged from segregation,” he added.

Hollmann additionally examined the remedy on two tuberculosis sufferers; one improved; the opposite didn’t. Though the drugs was imperfect and didn’t work for everybody, Hollmann was buoyed by its energy to set folks with leprosy free.

Hansen’s illness, generally referred to as leprosy, is a slow-growing an infection attributable to Mycobacterium leprae, a cousin of Mycobacterium tuberculosis, the micro organism answerable for tuberculosis. Throughout the time of Ball’s chaulmoogra analysis, leprosy was nonetheless steeped in stigma, simply because it was within the biblical period. These troubled have been handled harshly and compelled into everlasting isolation, despite the fact that leprosy was not simply transmitted. Untreated, it could actually trigger paralysis and develop into disfiguring. Leprosy damages the nerves and in addition impacts the eyes, nasal passages and pores and skin.

In Hawaii, folks with leprosy have been shipped out of sight, marooned on Molokai Island for all times. Many of the remoted have been Native Hawaiians. Till the Ball Technique, demise was their solely aid.

Alice Ball died at 24 on Dec. 31, 1916, in Seattle. She had taken a go away of absence from her instructing place due to an sickness that an article in The Pacific Industrial Advertiser, a Honolulu newspaper, attributed to publicity to chlorine fuel throughout a laboratory demonstration. (The faculty denied that declare.) Her demise certificates cites the trigger as tuberculosis.

“What a waste that she died in her 20s,” Gregory Petsko, an adjunct professor of bioengineering at Harvard Medical Faculty and emeritus professor of chemistry at Brandeis College in Waltham, Mass, mentioned in a cellphone interview. “Most chemists don’t hit their stride till their 30s or 40s. Simply think about what she may have finished if she had lived.”

Alice Augusta Ball was born on July 24, 1892, in Seattle, considered one of 4 kids of James Presley Ball Jr., a lawyer and newspaper editor, and Laura Louise (Howard) Ball, a studio photographer. Alice’s paternal grandfather was James Presley Ball Sr., a famous Nineteenth-century photographer and abolitionist.

On her beginning registration and demise certificates, Alice is listed as white, though her dad and mom described themselves as Black on their marriage certificates and in U.S. census data. “This will have had much less to do with phenotype and extra to do with what the Balls considered themselves culturally,” Quintard Taylor, an emeritus professor of American historical past on the College of Washington in Seattle and the founding father of the historical past web site Blackpast.org, mentioned by cellphone.

All through her secondary training, Ball excelled in science. She was one of many few women in her 1909 graduating class at Broadway Excessive Faculty to pay attention in its scientific program. She earned two Bachelor of Science levels from the College of Washington: one in pharmaceutical chemistry in 1912 and the opposite in pharmacy in 1914.

As an undergraduate, she wrote a paper with the chemist William Dehn, a professor on the College of Washington, based mostly on their analysis involving a sort of response referred to as a benzoylation. The paper was revealed within the prestigious Journal of the American Chemical Society.

It wasn’t till the Nineteen Seventies that Kathryn Takara, a College of Hawaii professor, and Stanley Ali, who had a private curiosity in Ball’s work, dug by way of the establishment’s archives to seek out proof of the true developer of the chaulmoogra remedy. In 2019 the London Faculty of Hygiene and Tropical Drugs honored Ball by putting her identify within the frieze of its most important constructing. In February 2022, Gov. David Ige of Hawaii declared Feb. 28 Alice Augusta Ball Day.

Twenty-first century scientists marvel at Ball’s potential to search out chaulmoogra’s energetic constituents utilizing her period’s bare-bones know-how. “Quite a lot of strategies again then weren’t as refined as they’re now so chemical instinct was crucial,” Gregory Petsko mentioned. “To do what she did when she did it was outstanding. She was a really proficient chemist.”
