Ludwig Salvator (1847-1915), Archduke of Austria, was the son of the Duke of Tuscany. Raised in Florence and Rome, Archduke Ludwig had already published several German-language travel books when he visited Los Angeles in the winter of 1876, not long after the city was linked directly by rail to the East. Los Angeles in the sunny seventies (1929) is an English translation of the archduke's account of that visit, published in German in 1878. It is organized to guide prospective emigrants considering the region as a place of settlement. Topics include climate, demographic patterns, agriculture, cattle-raising, industry, rail and steamship routes and postal service, and housing, as well as a brief history of the region and the problems of Chinese and Native American residents. The book closes with statistic-laden descriptions of visits to the San Gabriel Valley, Santa Monica, and Wilmington.
