Patrick Martins, 36
Breed saver
New York

-For his thesis on medieval food sculpture at the Tisch School of the Arts at New York University, Martins spoke to Carlo Petrini, the Rabelaisian founder of the international slow-food movement.

-Martins then started Slow Food USA.

-He soon helped found Heritage Foods USA, which has worked to rescue vanishing turkey breeds like the Bourbon Red — as well as the farmers raising them — through a mail-order campaign.

-In 2004, Martins left Slow Food to make Heritage Foods USA an independent company with the idea that the best way to save food is by eating it.

-Today, more than 300 chefs, including Mario Batali and David Chang, rely on his growing network of small breeders and slaughterhouses for their ‘‘noncommodity’’ meat and poultry, including Horned Dorset lamb and Highland cattle.

-he recently helped open an agriturismo (a working-farm B. and B.) and he will soon start a food-themed Internet radio station.
