George Preti (October 7, 1944 – March 3, 2020) was an analytical organic chemist who worked at the Monell Chemical Senses Center in Philadelphia, Pennsylvania.
Preti was also an adjunct professor in the Department of Dermatology of the University of Pennsylvania School of Medicine.
[3][4] His unique area of research resulted in hundreds of clinician-directed referrals of patients with an idiopathic body and oral malodor production problems.
His efforts in this area revealed a large, undiagnosed population of people suffering from trimethylaminuria, an odor-producing genetic disorder.
Preti’s work has frequently been cited by the news media, including The New York Times magazine section,[5] The Philadelphia Inquirer,[6] and ABC’s “Primetime: Medical Mysteries”.
