The chambelland firm began with two creative, free-thinking spirits. Thomas Teffri-Chambelland, a trained biologist, made a career change and became a baker. He started making organic sourdough bread and, in 2007, founded the École Internationale De Boulangerie, a training school for bakers. Nathaniel Doboin, a globe-trotting businessman with an initial experience working in advertising, decided to leave it all behind and throw himself into a meaningful food-related project.
