John Diedrich Spreckels (August 16, 1853 – June 7, 1926), the son of German-American industrialist Claus Spreckels, founded a transportation and real estate empire in San Diego, California, in the late 19th and early 20th centuries. The entrepreneur's many business ventures included the Hotel del Coronado and the San Diego and Arizona Railway, both of which are credited with helping San Diego develop into a major commercial center. Upon his death he was eulogized as "One of America's few great Empire Builders who invested millions to turn a struggling, bankrupt village into the beautiful and cosmopolitan city San Diego is today." Early years The oldest of five children, Spreckels was born in Charleston, South Carolina, though the family soon moved to New York City. Spreckels attended Oakland College and then the Polytechnic College in Hannover, Germany, where he studied chemistry and mechanical engineering until 1872. He returned to California and began working for his father, Claus Spreckels, who had grown extremely wealthy in the sugar business. In 1876 he went to the Hawaiian Islands, where he worked for his father's sugar business, Spreckels Sugar Company. Entrepreneur beginnings In 1880, with $2 million in capital, he organized J. D. Spreckels and Brothers, a company to establish a trade between the mainland United States and the Hawaiian Islands. The company began with one sailing vessel, the Rosario, and later controlled two large fleets of sail and steam ships. The firm also engaged extensively in sugar refining, and became agents for leading sugarcane plantations in Hawaii. Much of the development of commercial interests between the United States and Hawaii is due to this firm. The shipping and passenger line of this enterprise was the Oceanic Steamship Company, which was founded by J.D. Spreckels in 1881. Its inaugural service was between California and Hawaii and, later, also from California to Australia, New Zealand, Samoa and Tahiti. The various of the lines’ ships transported passengers, sugar and/or other food cargoes and provided mail service. For decades, the company provided the only mail service between the U.S. and Australia and New Zealand. The Oceanic ships that transported mail to Australia and New Zealand were the Alameda (3000 horsepower plant), Mariposa (3000 horsepower plant), the steamer Zealandia, the Sierra, the Sonoma and the Ventura. The Australia provided a 33-day direct mail service to Tahiti. In 1926 Oceanic became a subsidiary of Matson Navigation Company, a company which
