is the previously untold story of a pioneer who almost singlehandedly transformed the bankrupt village of San Diego into a thriving city. When he first dropped anchor in San Diego Bay in 1887, John Diedrich Spreckels set into motion a series of events that later defined the city. Within just a few years, this son of the German immigrant Claus Spreckels, known as the “Sugar King,” owned and controlled the majority of San Diego’s industry. After successfully building empires in sugar, shipping, and transportation and building development along the coast of California and across the Pacific, Spreckels rubbed shoulders with world leaders, successfully sued the U.S. government twice, and contributed to numerous educational, charitable, and cultural institutions in San Diego and San Francisco. Despite the fact that Spreckels created and owned much of San Diego’s early twentieth-century infrastructure, his name is unknown to many contemporary San Diegans. Nobody could have foreseen that Spreckels’s empire would be all but forgotten in so short a time. Sandra E. Bonura strives to correct this oversight by providing a behind-the-scenes look at Spreckels and his family’s role in business. This deeply researched biography paints a realistic portrait of cultural, economic, and political aspects of late nineteenth- and early twentieth-century California.
