Percy Lavon Julian (1899 – 1975) – Aero-foam
Percy Lavon Julian was a renowned chemist who made many significant inventions. One of his creations was a soy protein coating paper that was a cheaper alternative to milk protein. This paper was used in a product called Aero-Foam, which was used to smother fires from burning gasoline and oil. During World War II, the U.S. Navy also used Aero-Foam. Although Aero-Foam had slow knockdown characteristics, it was safe to use as long as it was applied above the burning liquid.
Julian’s most famous inventions were synthetic hormones, including physostigmine and cortisone, also derived from soybean plants. Physostigmine is still used to treat glaucoma, while the cortisone is used for rheumatoid arthritis. In addition to his scientific achievements, Julian was a prominent civil rights activist and raised money for the NAACP’s legal and education divisions.
