 I run Alcatraz", and later angrily refused Young a bible when he was in solitary confinement in D-Block.
 He departed Alcatraz in 1947 and was transferred to Leavenworth.
 He was married to Rosine (née Wahler) and lived on Alcatraz during his time as Associate Warden.

In Greek mythology and Roman Mythology, Hector (Ἕκτωρ "Hektōr", ] ) was a Trojan prince and the greatest fighter for Troy in the Trojan War.
 As the first-born son of King Priam and Queen Hecuba, who was a descendant of Dardanus and Tros, the founder of Troy, he was a prince of the royal house and the heir apparent to his father's throne.
 He was married to Andromache, with whom he had an infant son, Scamandrius (whom the people of Troy called Astyanax).
 He acted as leader of the Trojans and their allies in the defense of Troy, "killing 31,000 Greek fighters", offers Hyginus.
 During the European Middle Ages, Hector figures as one of the Nine Worthies noted by Jacques de Longuyon, known not only for his courage but also for his noble and courtly nature.
 Indeed, Homer places Hector as peace-loving, thoughtful as well as bold, a good son, husband and father, and without darker motives.
 James Redfield writes of Hector as a "martyr to loyalties, a witness to the things of this world, a hero ready to die for the precious imperfections of ordinary life."
