At the turn of the 20th century, San Diego was poised on the edge of significant change, transitioning from a quiet, modestly populated town into a city that would soon experience rapid growth and development. This period was marked by an influx of innovation, driven by the optimism and challenges of a new century.

The population at this time was just over 17,000 according to the 1900 U.S. Census, but the city was about to witness a substantial increase. By 1910, the number of residents had nearly doubled, a testament to the nationwide population boom and the allure of California as a destination for opportunity and prosperity. This growth was spurred further by key events and developments that shaped the city's future.

One significant event that influenced San Diego's growth was the establishment of the Panama-California Exposition in 1915. Held in Balboa Park, the exposition celebrated the opening of the Panama Canal and showcased San Diego as the first U.S. port of call on the Pacific Coast route. This event put San Diego on the map for many Americans and attracted visitors and new residents alike, highlighting the city's strategic importance and its potential as a cultural and economic hub.

The early 20th century also saw San Diego capitalizing on its natural harbor, which became a pivotal asset for the city's economic development. The harbor facilitated trade and military operations, particularly as the U.S. Navy began to recognize the strategic importance of the Pacific region. The establishment of naval bases and infrastructure contributed to San Diego's growth and its emerging identity as a military town.

Despite these advancements, San Diego faced challenges typical of rapid urbanization, including the need for improved infrastructure and public services to accommodate its growing population. Issues such as water supply, transportation, and public health became pressing concerns that required innovative solutions.

Moreover, San Diego's cultural landscape was also evolving. The city's natural beauty, combined with its mild climate, made it an attractive destination for tourists and health seekers from across the country. The arts, sciences, and education began to flourish as the city expanded, laying the groundwork for the rich cultural scene that San Diego is known for today.

The turn of the 20th century was a pivotal time for San Diego, marking the beginning of its journey from a small town to a major city on the West Coast. This era of growth and transformation set the stage for the dynamic, diverse, and vibrant metropolis that San Diego would become.
