Henry Thoreau, bachelor of nature by Léon Bazalgette is a biography written in the early 20th century. It offers a vivid, reflective portrait of Henry David Thoreau’s formation, centering on his family origins, childhood in Concord, education, first jobs, and the outdoor passions that forged his outlook. The focus is on the making of a solitary, nature-obsessed moralist whose independence resists convention. The opening of the biography begins with an author’s note about relying on contemporaries to complete Thoreau’s portrait, then turns to ancestry and setting: the immigrant seaman-merchant John Thoreau who dies in Concord, the modest fortunes and struggles of his son John, and the spirited Cynthia Dunbar with her Loyalist-Jones lineage and flamboyant brother Charles. It recounts Henry’s birth on the edge of Concord in the early 19th century, a childhood saturated with rivers, ponds, woods, Indians glimpsed at fairs, winter skating, and boyish expeditions with his adored older brother John. Schooling leads to the Concord Academy and then Harvard, where he feels class distance, studies voraciously, dresses in a conspicuous green coat, grows inward and critical, and begins to articulate a fierce independence. Returning home, he helps with the family pencil business, briefly teaches in the town school but resigns rather than flog pupils, and then, with John, founds a humane, lively private school that mixes classics with fieldwork, friendship, and long walks. Alongside teaching, he hunts, fishes, keeps a meticulous journal, and deepens his intimacy with the local landscape. The section culminates in the brothers building a green-and-blue dory and launching a joyful voyage up the Concord and Merrimack—camping by rivers, passing locks and canal boats, meeting workers and farmers, and savoring solitude—until rapids force them to leave the boat and continue on foot toward the mountains, their adventure still unfolding.
