Alonzo Horton (1813-1909) is often known as the father of modern San Diego. He was born in upper New York State and worked as an itinerant trader. In 1867, he attended a lecture in which the California coast and its harbors were described. He was so inspired by this that he immediately sold all his holdings to move to San Diego, buy land, and build a city. At the time, San Diego was but a village of roughly 2,000 people. Through persistent land acquisition and development, Horton eventually built houses, office buildings, and a long wharf at the foot of Fifth Avenue to enable commercial vessel traffic. Horton was also active in the efforts to bring a railroad to San Diego, and successfully relocated the center of San Diego's development from Old Town to the waterfront. His many significant contributions laid the foundations for San Diego's modern urban growth. Producer Peter Hamlin and historian Clare Crane discuss with their guests the growth of San Diego from the 1860s to 1900, a period which was most notable for the boom of the 1880s following completion of the railroad to San Diego. The great increase in population and real estate development that resulted from the railroad's nationwide advertising campaign made possible the financing of urban necessities and amenities such as sewer, water, transit; and the beginning of cultural developments such as musical and literary organizations, parks and opera houses. The foundations of San Diego's urban development were established in this era. June Reading discusses William Heath Davis, Thomas Whaley, and other early developers in San Diego before Horton came. Shirley Vance describes Horton's earlier venture in city-building in Hortonville, Wisconsin. Elizabeth MacPhail recounts Horton's coming to San Diego, purchasing land, promoting urban development, and participating in significant activities in San Diego until his death in 1909; she comments on Horton's character, and his successes and failures. Frank Curran talks about plans to revitalize downtown San Diego, and points out some of the problems that resulted from Horton's gridiron street layout.
