Panama–California Exposition

The Panama–California Exposition was a world exposition held in San Diego, California, between January 1, 1915, and January 1, 1917. The exposition celebrated the opening of the Panama Canal, and was meant to tout San Diego as the first United States port of call for ships traveling north after passing westward through the canal. The fair was held in San Diego's large urban Balboa Park. The park held a second Panama-California exposition in 1935.

Proposal and formation
In 1909, San Diego's Chamber of Commerce president and local businessman Gilbert Aubrey Davidson proposed an exposition to commemorate the completion of the Panama Canal. San Diego's population in 1910 was 37,578, and it would be the least populated city to ever host an international exposition. In contrast, San Francisco had a population nearly 10 times larger and would ultimately be supported by politicians in California and Washington, D.C. for the official Panama Canal exposition, the Panama–Pacific International Exposition. Although representatives from San Francisco urged San Diego to end its planning, San Diego pressed forward for a simultaneous exposition. Several San Franciscans persuaded both members of Congress and President William Howard Taft to deny support for San Diego's exposition in exchange for pledged political support for Taft's campaign against Republicans. With no federal and little state government funding, San Diego's exposition would be on a smaller scale with fewer states and countries participating.

The Panama–California Exposition Company was formed in September 1909 and its board of directors was soon led by president Ulysses S. Grant Jr. and vice president John D. Spreckels. After Grant resigned in November 1911, real estate developer "Colonel" D. C. Collier, was made president of the exposition. He was responsible for selecting both the location in the city park and the Pueblo Revival and Mission Revival architectural styles. Collier was tasked with steering the exposition in "the proper direction," ensuring that every decision made reflected his vision of what the exposition could accomplish. Collier once stated "The purpose of the Panama–California Exposition is to illustrate the progress and possibility of the human race, not for the exposition only, but for a permanent contribution to the world's progress." The exposition's leadership changed again in early March 1914, when Collier encountered personal financial issues and resigned. He was replaced by Davidson, who was also joined by several new vice presidents.

By March 1910, $1 million ($ today) was raised for the expo by the Panama–California Exposition Company through selling subscriptions. A bond measure later that year provided an additional $1 million solely for improving permanent fixtures in the park. Funding for the California State Building was provided through appropriation bills totaling $450,000 ($ today) signed by Governor Hiram Johnson in 1911 and 1913.

Design
Fair officials first sought architect John Galen Howard as their supervisory architect. With Howard unavailable, on January 27, 1911, they chose New York architect Bertram Goodhue and appointed Irving Gill to assist him. By September 1911 Gill had resigned and was replaced by Carleton Winslow of Goodhue's office. The original landscape architects, the Olmsted Brothers, likewise left the project, and were replaced by fair official Frank P. Allen Jr.

Exposition site
The exposition was held in Balboa Park, which spanned 1400 acre. For the first few decades of its existence, "City Park" remained mostly open space; lacking trees and covered in native wildflowers, the park was home to bobcats, rattlesnakes, coyotes, and other wildlife. Numerous proposals, some altruistic, some profit-driven, were brought forward for the development and use of the land during this time. During construction of the exposition facilities in 1910, a contest was held that renamed the park after Vasco Núñez de Balboa, the first European to cross Central America and see the Pacific Ocean.

Spanish Colonial Revival architecture
Goodhue and Winslow advocated a design that turned away from the more modest, indigenous, horizontally oriented Pueblo Revival and Mission Revival, towards a more ornate and urban Spanish Baroque. Contrasting with bare walls, rich Mexican and Spanish Churrigueresque decoration would be used, with influences from the Islamic and Persian styles in Moorish Revival architecture. For American world's fairs, this was a novelty. The design was an intentional contrast to most previous Eastern U.S. and European expositions, which had been done in neoclassical and Beaux-Arts styles, with large formal buildings around large symmetric spaces; San Francisco's Panama–Pacific International Exposition was largely Beaux-Arts style. Goodhue had already experimented with Spanish Baroque in Havana, at the 1905 La Santisima Trinidad pro-cathedral, and the Hotel Colon in Panama. Some of his specific stylistic sources for San Diego are the Giralda Tower at the Seville Cathedral, the Mexico City Metropolitan Cathedral, and the Cathedral of Our Lady of the Assumption, Oaxaca.

Goodhue personally designed the largest and most ornate building on the site, the California Building, with its historical iconography; he sketched two other buildings, provided Winslow and Allen with his photographs and drawings from examples in Spain and Mexico, and reviewed their developed designs. The original ensemble of buildings featured various stylistic and period references. Taken together, they constituted something like a recapitulated history of Spanish colonial in North America, from Renaissance Europe sources, to Spanish colonial, to Mexican Baroque, to the vernacular styles adopted by the Franciscan missions up the California coast. The Botanical Building was designed by Winslow with help from Allen and Thomas B. Hunter in the style of a Spanish Renaissance greenhouse. This mix of influences is representative of Spanish Colonial Revival architecture, which the Exposition popularized in the United States. Prior to the exposition, San Diego had predominately featured Victorian architecture with some elements of classical styles. The popularity of the expo led to more emphasis on mission architecture within the city.

After the Exposition, Goodhue moved on to other national projects, while Winslow stayed on in southern California, continuing to produce his own variations of the style at the Bishop's School in La Jolla and the 1926 Carthay Circle Theatre in Los Angeles. Winslow was also instrumental in persuading the city of Santa Barbara to adopt Spanish Colonial Revival as the officially mandated civic style after its 1925 earthquake.

The temporary installations, decoration, and landscapes of Balboa Park were created with some large spaces and numerous paths, small spaces, and courtyard Spanish gardens. The location was also moved from a small hillock to a larger and more open area, most of which was intended to be reclaimed by the park as gardens.

Construction
The groundbreaking ceremony for the site of the expo was held on July 19, 1911. To make room for the exposition planned layout, several city buildings, machine shops, and a gunpowder magazine were moved offsite. The first building to begin construction was the Administration Building, which started in November 1911 and completed in March 1912. Visitors interested in watching the ongoing construction before the exposition's official opening were charged admission of $0.25 ($ today).

Layout
The layout of the 640 acre expo was contained by three entrances on the west, north, and east.

The East Gateway was approached by drive and San Diego Electric Railway trolley cars winding up from the city through the southern portion of the park.

From the west, the Cabrillo Bridge's entrance was marked with blooming giant century plants and led straight to the dramatic West Gate (or City Gate), with the city's coat-of-arms at its crown. The archway was flanked by engaged Doric orders supporting an entablature, with figures symbolizing the Atlantic and Pacific oceans joining waters together, in commemoration of the opening of the Panama Canal. These figures were the work of Furio Piccirilli.

While the west gateway was part of the Fine Arts Building, the east gateway was designed to be the formal entrance for the California State Building. The East or State Gateway carried the California state coat-of-arms over the arch. The spandrels over the arch were filled with glazed colored tile commemorating the 1769 arrival of Spain and the 1846 State Constitutional Convention at Monterey.

Near a large parking lot, the North gate led to the 'Painted Desert' and 2500 ft long Isthmus street. The Santa Fe Railway-sponsored 'Painted Desert' (called "Indian Village" by guests), a 5 acre, 300-person exhibit populated by seven Native American tribes including the Apache, Navajo, and Tewa. The 'Painted Desert', which design and construction was supervised by the Southwestern archeologist Jesse L. Nusbaum, had the appearance of a rock structure but was actually wire frames covered in cement.

The Isthmus was surrounded by concessions, amusement rides and games, a replica gem mine, an ostrich farm, and a 250 ft replica of the Panama Canal. One of the concessions along the isthmus was a "China Town".

Permanent structures
From the start, the Cabrillo Bridge, the domed-and-towered California State Building and the low-lying Fine Arts Building were intended to be permanent additions to the park; the latter two are now part of the National Register of Historic Places-listed California Quadrangle. The Botanical Building would protect heat-loving plants, while the Spreckels Organ Pavilion would assist open-air concerts in its auditorium. The Botanical Building was completed for $53,400 ($ today).

The Cabrillo Bridge was built to span the canyon, and its long horizontal stretch ending in a great upright pile of fantasy buildings would be the crux of the whole composition.

The focus of the fair was the Plaza de California (California Quadrangle), an arcaded enclosure often containing Spanish dancers and singers, where both the approach bridge and El Prado terminate. The California State Building and the Fine Arts Building framed the plaza, which was surrounded on three sides by exhibition halls set behind an arcade on the lower story. Those three sides, following the heavy massiveness and crude simplicity of the California mission adobe style, were without ornamentation. This contrasted with the front facade of the California State Building, 'wild' with Churrigueresque complex lines of mouldings and dense ornamentation. Next to the frontispiece, at one corner of the dome, rose the 200 ft tower of the California Building, which was echoed in the less prominent turrets of the Southern California counties and the Science and Education buildings. The style of the frontispiece was repeated around the fair.

Temporary buildings
The architecture of the "temporary buildings" was recognized, as Goodhue described, as "being essentially of the fabric of a dream—not to endure but to produce a merely temporary effect. It should provide, after the fashion that stage scenery provides—illusion rather than reality."

The "temporary buildings" were formally and informally set on either side of the wide, tree-lined central avenue. El Prado extended along the axis of the bridge and was lined with trees and streetlights, with the front of most buildings lined with covered arcades or portales. The Prado was intended to become the central path of a great and formally designed public garden. The fair's pathways, pools, and watercourses were supposed to remain while the cleared building sites would become garden. Goodhue emphasized that "only by thus razing all of the Temporary Buildings will San Diego enter upon the heritage that is rightfully hers". However, many of the "temporary" buildings were retained and reused for the 1935 fair. Four of them were demolished and rebuilt in their original style toward the end of the 20th century; they are now called the House of Charm, the House of Hospitality, Casa del Prado, and Casa de Balboa, and are included in the National Register of Historic Places-listed El Prado Complex.

Transportation
One of the main considerations for San Diego leaders concerning the Panama–California Exposition was transportation. At the request of John D. Spreckels and his San Diego Electric Railway Company, the park's layout design incorporated an electric railway that ran near the east gate of the park. To service the large number of people that were to attend the exposition, streetcars were built that could handle the traffic of the event as well as the growing population of San Diego. The routes ultimately spanned from Ocean Beach, through Downtown, Mission Hills, Coronado, North Park, Golden Hill, and Kensington, even briefly serving as a link to the U.S.–Mexico border. Today, only three of the original twenty-four Class 1 streetcars remain in existence.

At the beginning of the exposition, 200 small wicker motorized chairs, known as electriquettes, were available for rent by visitors. Constructed by the Los Angeles Exposition Motor Chair Company, these slow-speed transports held two to three people and were used for traveling throughout the majority of the exhibition. Electriquette replicas returned for the centennial celebration in 2015.

Other features
Additional elements of the exposition included an aviary, rose gardens, and animal pens. Throughout the exposition grounds there were over two million plants of 1,200 different types. Peacocks and pheasants freely wandered through the fairgrounds, and pigeons were frequently fed by guests.

The exposition did not initially feature any buildings representing foreign countries, though a handful of U.S states held exhibits: Kansas, Montana, Nevada, New Mexico, Washington, and Utah. In contrast, the San Francisco Panama-Pacific Exposition featured exhibits from 22 countries and 28 U.S. states. Various countries participated in the exposition's 1916 extension.

The United States Marines, Army, and Navy were featured at the expo, with exhibits, onsite tent cities, parades, band concerts, and live mock battles.

Opening
At midnight on December 31, 1914, President Woodrow Wilson ceremoniously pushed a telegraph button in Washington, D.C. to open the expo by turning on the power and lights at the park. In addition, a lit balloon located 1,500 feet above the park further brightened the exposition. Guns at the nearby Fort Rosecrans and on Navy ships in San Diego Bay also were fired to signal the opening.

Admission for adults was $0.50 ($ today) and $0.25 ($ today) for children. Based on varying sources, the opening day's attendance was between 31,836 and 42,486. By the end of the first month, daily attendance decreased, with an average number of attendees at 4,783 a day, which decreased to 4,360 by February. However, the expo made ($ today) profit in its first three months. By May, the average daily attendance had increased to 5,800 and in July the total attendance had reached a million visitors.

Notable visitors to the expo included Vice President Thomas R. Marshall, Secretary of State William Jennings Bryan, Secretary of the Navy and future President Franklin D. Roosevelt, former presidents William Howard Taft and Theodore Roosevelt, inventor Thomas Edison, and automobile businessman Henry Ford. The attempt to "put San Diego on the map" with national attention was successful. Even Pennsylvania's Liberty Bell made a brief three-day appearance in November 1915. At the end of 1915, total visitors reached over two million and the expo had turned a small profit of $56,570 ($ today).

Extension
Prior to the end of 1915, plans began circulating for extending the exposition for another year. Most of the board of directors, however, were not able to continue into the new year and resigned. Funding for the 1916 addition came from Los Angeles, local businessman, proceeds from the 1915 expo, leftover funding from the Panama–Pacific International Exposition, and chambers of commerce outside of San Diego. On March 18, 1916, Secretary of the Navy Josephus Daniels pushed a button in Washington, D.C. that sounded a gong in the Plaza de Panama to commemorate "Exposition Dedication Day". The fair was rechristened the Panama–California International Exposition. By this point, international exhibitors from the recently closed San Francisco exhibition had arrived in San Diego, and the expo had exhibits from Brazil, Canada, France, Germany, Italy, the Netherlands, Russia, and Switzerland. Some of these exhibitors were unable to return to Europe due to World War I which had been raging since 1914. Additional exhibits included an ice rink, an alligator farm, and performance shows. Some of the original buildings from the prior year were repurposed for new exhibits.

In November 1916, Gilbert Davidson asked the Park Board for an additional three-month extension into 1917, but the expo was concluded on January 1, 1917. Events on the final day included a military parade in the Plaza de Panama, a mock military battle, and an opera ceremony at the organ pavilion. At midnight, the lights were turned off and pyrotechnics above the organ spelled "WORLD PEACE–1917". The total attendance for the second year was just under 1.7 million people. Over the two years a slight profit was earned over the total cost of organizing and hosting the expo.

Legacy
The Exposition left a permanent mark in Balboa Park, which had been mostly open space before the fair. Former President Theodore Roosevelt spoke to San Diegans at the Spreckels Organ Pavilion in July 1915, urging San Diego to keep the exhibition buildings permanently. Even before the end of the first year of the expo, an organization was established to determine how the temporary buildings could be developed for museum use. The exposition also led to the eventual establishment of the San Diego Zoo in the park, which grew out of abandoned exotic animal exhibitions from the Isthmus portion of the expo.

Buildings from the exposition still standing include:
 * Botanical Building, one of the largest lath-covered structures then in existence, contained a rare collection of tropical and semitropical plants. It is well back from the Prado behind the long pool, La Laguna de Las Flores.
 * Cabrillo Bridge (completed April 12, 1914)
 * California Bell Tower, completed 1914, 198 ft feet tall to the top of the iron weathervane, which is in the form of a Spanish ship; one of the most recognizable sights in San Diego as "San Diego's Icon".
 * California State Building, completed October 2, 1914, which now houses the Museum of Us. The design was inspired by the church of San Diego in Guanajuato, Mexico.
 * Chapel of St. Francis of Assisi (south side of Fine Arts Building); now the Saint Francis Chapel operated by the Museum of Us.
 * Fine Arts Building (on south side of Plaza of California), now part of the Museum of Us.
 * Spreckels Organ Pavilion (dedicated December 31, 1914).



During the expo, Franklin D. Roosevelt, then Assistant Secretary of the Navy, told reporters that San Diego would become a Navy port. This declaration would gradually result in multiple Navy installations in and around San Diego that continue today. Shortly after the end of the expo, the Army and Marines temporarily used several empty expo buildings until nearby bases were completed.

The Exposition was the setting for a 1915 comedy film Fatty and Mabel at the San Diego Exposition starring Roscoe Arbuckle and Mabel Normand.

Later exposition and rebuilding
The California Pacific International Exposition at the same site in 1935 was so popular that some buildings were rebuilt to be made more permanent. Many buildings (original or reconstructed) remain in use today, and are used by several museums and theaters in Balboa Park.

In the early 1960s destruction of a few of the buildings and replacement by modern, architecturally clashing buildings created an uproar in San Diego. In 1967, citizens formed A Committee of One Hundred to protect and preserve the park buildings. They convinced the City Council to require new buildings to be built in Spanish Colonial Revival Style and worked with various government agencies to have the remaining buildings declared National Historic Landmarks in 1977. In the late 1990s, the most deteriorated buildings and burned buildings were rebuilt, preserving the original style.

Centennial
The City of San Diego held a major observation for the 2015 centennial of the Exposition, with numerous events and exhibits. A proposal to remove vehicle traffic and parking from the central plazas proved controversial and was eventually scrapped.
