William Dean Howells's warm, intimate portrait of Mark Twain begins with their first meeting in Boston and grows into a lifelong friendship marked by laughter, admiration, and repeated visits in Hartford and New York. Twain emerges as a dazzling presence: theatrically dressed, mischievous, endlessly talkative, and yet rooted in a boyish originality that made his humor feel inseparable from deeper wisdom. Howells moves through literary gatherings with Fields, Aldrich, Bret Harte, and Ralph Keeler, then into Twain's years of booming success, when subscription publishing, magazine fame, and theatrical ventures like Colonel Sellers and The Gilded Age turned him into a public sensation. Beneath the comic energy, however, lies a tender domestic life centered on Olivia Langdon Clemens, whose strength, kindness, and moral grace shaped Twain profoundly. Howells also reveals Twain's reading habits, his instinctive and unacademic style, his cooperative dealings with editors, and his strong moral sympathy for labor, equality, and human dignity. The result is a vivid, affectionate study of a uniquely original American genius. This edition has been fully restored with modern typesetting, custom cover design.
