Please review this promotional page from 1943, created by the San Diego Chamber of Commerce to celebrate its 73rd anniversary. The San Diego Chamber of Commerce was established in 1870 by Alonzo Horton, a well-known local entrepreneur who served as the chamber's first treasurer. The chamber initially worked to develop railway infrastructure, support harbor commerce, and encourage settlement and tourism in San Diego. In the early 20th century, it played a significant role in establishing military installations. This had a huge positive impact on the local economy. Let's not forget about the 1915 Panama-California Exposition! The chamber was the driving force behind that incredible event, which put San Diego on the map.
