Writer Jack Adler describes 75 famous friendships throughout history from mythical to contemporary times. Along the way, the lives and personalities of artists, politicians, philosophers, soldiers, and outlaws are outlined, including some personal details that may not be well-known. The author shows how contrasting as well as comparable personalities, characters and temperaments can support and strengthen each other, and explores the range of ties that may influence a person during one phase of life or may become the center of one's life altogether.
