The concept of the pheromone party was invented by Judith Prays, a 25 year-old web developer living in Atlanta, US. Having persistently tried to match up with potential partners on an intellectual basis, but without much success, Prays decided to date someone purely on the grounds of physical attraction. This resulted in one of the most successful relationships she’d ever had. Observing that she’d been particularly obsessed with the way this guy smelt, and aware of previous experimentation with pheromones, Prays had the idea to throw a pheromone party, the first event taking place in New York in late 2010.
