William Alexander Leidesdorff was born in 1810 in the Danish West Indies. His father, Alexander Leidesdorff, was a Dane, and
his mother, Anna Maria Spark, was a creole of mixed-race ancestry. After conducting trade in New Orleans, Leidesdorff came
to California in 1841 as master of the schooner Julia Ann, making frequent trips between San Francisco (then Yerba Buena) and Honolulu to sell hides and tallow. In 1843, he purchased
a lot in Yerba Buena at the corner of Clay and Kearny streets, building a large warehouse on the waterfront in 1844 and the
City Hotel in 1846. Naturalized as a Mexican citizen in 1844, Leidesdorff obtained a 35,000-acre land grant on the American
River known as Rancho Río de los Americanos. A prominent merchant and landowner, Leidesdorff also served in a number of civic
positions, including United States vice-consul to Mexico (appointed by Thomas Larkin in 1845) and treasurer of San Francisco.
