"Alcatraz Island: Memoirs of a Rock Doc" vividly chronicles the experiences of Milton Daniel Beacher, M.D., an Alcatraz medical officer from 1937-1938. Based on his original journal entries, Beacher’s memoir presents a compelling behind-the-bars depiction of life on the Rock for prisoners like Al Capone, "Machine Gun" Kelly, and Alvin Karpis. It includes details of a long prison strike, the Cole/Roe escape, an attempted mass break, and a little history. Befriended by some prisoners, their first-person narratives and original poetry are memorialized.
