Spalding had been a prominent member of the Theosophical Society under William Quan Judge. In 1900, Spalding moved to San Diego with his newly acquired second wife, Elizabeth and became a prominent member and supporter of the Theosophical community Lomaland, which was being developed on Point Loma by Katherine Tingley. He built an estate in the Sunset Cliffs area of Point Loma where he lived with Elizabeth for the rest of his life. The Spaldings raised race horses and collected Chinese fine furniture and art. The Spaldings had an extensive library which included many volumes on Theosophy, art, and literature. In 1907–1909 he was the driving force behind the development of a paved road, known as the "Point Loma boulevard," from downtown San Diego to Point Loma and Ocean Beach; the road also provided good access to Lomaland. It later provided the basis for California State Route 209. He proposed the project, supervised it on behalf of the city, and paid a portion of the cost out of his own pocket. He joined with George Marston and other civic-minded businessmen to purchase the site of the original Presidio of San Diego, which they developed as a historic park and eventually donated to the city of San Diego. He ran unsuccessfully for the United States Senate in 1910 as a Republican, but lost to eventual winner John D. Works by a vote of 92–21 in the California legislature. He helped to organize the 1915 Panama–California Exposition, serving as second vice-president. Death He died of a stroke on September 9, 1915, in San Diego, one week after his 66th birthday. His ashes were scattered at his request. Legacy He was elected to the Baseball Hall of Fame by the Veterans Committee in 1939, as one of the first inductees from the 19th century at that summer's opening ceremonies. His plaque in the Hall of Fame reads "Albert Goodwill Spalding. Organizational genius of baseball's pioneer days. Star pitcher of Forest City Club in late 1860s, 4-year champion Bostons 1871–75 and manager-pitcher of champion Chicagos in National League's first year. Chicago president for 10 years. Organizer of baseball's first round-the-world tour in 1888." His nephew, also named Albert Spalding, was a renowned violinist.
