""My mother didn't try to stab my father until I was six,"" actor and author Alan Alda writes at the beginning of his autobiography. The child of a well-known actor, Alda (born Alphonso D'Abruzzo) spent his early years on the road with a burlesque troupe. The time spent on the stage wings, watching his father perform, made a profound impact on the youngster, igniting a desire to entertain others that has stayed with him his entire life. Just as profound was his mother's losing battle with mental illness; Alda spent much of his adult life attempting to reconcile his resentment of her outbursts and unmanageable behavior coupled with her unbridled enthusiasm for life and encouragement. Fueled by a desire to learn and constantly question, Alda carves out his own path; he marries and starts a family while continuing to act and write. His enthusiasm for new experiences-improv, musical theater, television, film-enabled him to grow as an artist, resulting in better jobs. (Alda discussed his most famous role, as Hawkeye Pierce on M*A*S*H*, in 1985's The Last Days of M*A*S*H*.) Humble to a fault, Alda spends more time discussing his formative years than he does on his Emmies and Oscar nominations, which he glosses over. A significant chunk of the final third of the book is devoted to an epiphany Alda had after a health scare in Chile. It runs a bit long, but Alda's conversational style keeps the story on track. It's a brief but entertaining autobiography tempered with humility and a depth rarely found in celebrity memoirs.
