The Experiment, an independent publisher of a wide range of nonfiction, has acquired Appletree Press, a publisher of titles on health, food, and lifestyle, in a transaction that closed at the end of December 2019.

Founded in 1989 by its publisher, Linda Hachfeld, Appletree Press publishes a list of cookbooks, journals, and specialized titles for children that provide authoritative information on heart disease, weight management, diabetes, and other medical conditions. Among its bestselling titles are Cooking à la Heart and The Essential Arthritis Cookbook. Both titles have sold more than 100,000 copies.

Hachfeld, who will continue to provide editorial direction at Appletree Press, praised the acquisition, describing the Experiment as “an independent publisher committed to publishing practical, nutrition-focused books.”

Beginning in 2021, the Experiment will publish revised editions of a number of Appletree Press, among them Cooking à la Heart, Let’s Cook! Healthy Meals for Independent Living, and The Diabetic Goodie Book.

The Experiment was founded in 2009 by Matthew Lore and Peter Burri. The house specializes in nonfiction titles in the health, fitness, home and garden, science, food, and self-help categories, as well as children's books. The publisher has about 20 employees based in New York City and a backlist of about 300 active titles. The Experiment’s books are distributed in the U.S. by Workman Publishing Company, by the University of Toronto Press in Canada, and sold by Melia Publishing Services in the U.K., and are represented by Affirm Press in Australia and New Zealand.

Lore, CEO of the Experiment, said that in addition to continuing to oversee the Appletree list, Hachman will also pursue “special sales opportunities that have been a hallmark of Appletree Press success.” Lore said: “These books have more currency than ever, and we’re excited to update them, and to sell them across the entire retail marketplace.”
