At the crossroads between injustice and genius lies the story of Alice Ball. This pharmaceutical chemist, at just 23 years old, faced the challenge of leprosy in Hawaii. Her goal was chaulmoogra oil, an ancestral remedy but with limited use. Alice succeeded in isolating its active principles and creating the first effective injectable treatment, the Ball Method, which gave a chance to thousands of people confined in leper colonies.
From the viscous flask to the syringe: the esterification process 💉
The problem with chaulmoogra oil was its viscosity and insolubility in water, making it toxic and ineffective when ingested or injected. Ball developed a chemical process of methylation esterification. She transformed the fatty acids of the oil into ethyl esters, lighter and more soluble compounds. This change allowed subcutaneous and intramuscular administration, facilitating the body's safe absorption of the active principles with a clear therapeutic effect.
The "ghost effect" in scientific credits 👻
Ball's story has a repeated script: the researcher who disappears from the paper. After her death, the president of her university, Arthur Dean, continued her work and published without crediting her, naming the treatment the Dean Method. For decades, Ball was a footnote. Until, like in good movies, other scientists rescued her name from oblivion. A reminder that sometimes, the most complicated experiment is getting your name to remain on the study's cover.
