More than fifteen million Americans currently practice yoga (according to Yoga Journal), but how many of them know the true story of how Downward Dog first captivated America? Resurrecting a fascinating and forgotten tale, journalist Robert Love returns to the Gilded Age, when Dr. Pierre Bernard (né Perry Baker in Iowa) revived a discipline banned in Victorian India, packaged it for Americans, and taught legions of followers, who bankrolled his luxurious Hudson River ashram- the first in the nation. Filled with Jazz Age celebrities, heiresses, spies, and outraged clergy, The Great Oom is the enthralling life story of the unlikeliest of gurus, and a stunning saga of mysticism, intrigue, and the American dream.
