01 Apr New York Times: George Preti, 75, dies; studied bodily odors as biological clues
George Preti, an organic chemist who devoted his career to studying bodily odors and how they can be weaponized in detecting disease, died on March 3 in Hatboro, Pa. He was 75.
The cause was bladder cancer, according to the Monell Chemical Senses Center, a Philadelphia-based research institution funded by philanthropy, government grants and corporate sponsorships.
Ever since he was a regular passenger on the New York City subways, Dr. Preti (pronounced PRET-ee) had thrived on pungency, discovering how individual smells can distinguish human beings like fingerprints.
