Bill Struth is the most celebrated Manager in the history of Rangers Football Club. In his 34 year tenure, he led the club to 30 major trophies and nurtured many of the club's greatest players. To them, he was simply "Mr. Struth"—a father figure who guided them with the principle that "to be a Ranger is to sense the sacred trust of upholding all that such a name means in this shrine of football." If these words set the ideals for his players to attain, his own personal life was clouded by moments of indiscretion which were to influence the course of his life and career. Drawing on family accounts and Rangers archives, the book explores his early life in Edinburgh and Fife, as well as his celebrated years in Glasgow. It recounts his career in professional athletics and in football with Heart of Midlothian, Clyde, and ultimately, Rangers. It reflects on the legacy of the Struth era and his influences that remain at Ibrox today.
