Back to the blog, after a break of 12 months. I haven't quite finished with the Spreckels Family as Emma Spreckels also had a brother called John Dietrich Spreckels. He left San Francisco and went to Germany to study chemistry and mechanical engineering. On his return he worked for his Father, Claus Spreckels, in the sugar business. Having established a shipping company to get the sugar from Hawaii to the USA he visited San Diego and decided to invest in the city. He bought land and acquired businesses, such as the railway system, newspapers and hotels. In 1906, after the San Francisco Earthquake, he and his family relocated there. John Dietrich Spreckels had married Lillie Siebein and they had four children. He must take the credit for the development of the city of San Diego from its modest beginnings to the wealthy city that it became.
