Fort Mason in the context of "Bay Area"

The San Francisco Bay Area, commonly known as the Bay Area, is a region of California surrounding and including San Francisco Bay, and anchored by the cities of Oakland, San Francisco, and San Jose. The Association of Bay Area Governments defines the Bay Area as including the nine counties that border the estuaries of San Francisco Bay, San Pablo Bay, and Suisun Bay: Alameda, Contra Costa, Marin, Napa, San Mateo, Santa Clara, Solano, Sonoma, and San Francisco. Other definitions may be either smaller or larger, and may include neighboring counties which are not officially part of the San Francisco Bay Area, such as the Central Coast counties of Santa Cruz, San Benito, and Monterey, or the Central Valley counties of San Joaquin, Merced, and Stanislaus. The Bay Area is known for its natural beauty, prominent universities, technology companies, and affluence. The Bay Area contains many cities, towns, airports, and associated regional, state, and national parks, connected by a complex multimodal transportation network.

The earliest archaeological evidence of human settlements in the Bay Area dates back to 8000–10,000 BC. The oral tradition of the Ohlone and Miwok people suggests they have been living in the Bay Area for several hundreds if not thousands of years. The Spanish empire claimed the area beginning in the early period of Spanish colonization of the Americas. The earliest Spanish exploration of the Bay Area took place in 1769. The Mexican government controlled the area from 1821 until the 1848 Treaty of Guadalupe Hidalgo. Also in 1848, James W. Marshall discovered gold in nearby mountains, resulting in explosive immigration to the area and the precipitous decline of the Native population. The California gold rush brought rapid growth to San Francisco. California was admitted as the 31st state in 1850. A major earthquake and fire leveled much of San Francisco in 1906. During World War II, the Bay Area played a major role in America's war effort in the Asiatic-Pacific Theater, with the San Francisco Port of Embarkation, of which Fort Mason was one of 14 installations and location of the headquarters, acting as a primary embarkation point for American forces. Since then, the Bay Area has experienced numerous political, cultural, and artistic movements, developing unique local genres in music and art and establishing itself as a hotbed of progressive politics. The postwar Bay Area saw large growth in the financial and technology industries, creating an economy with a gross domestic product of over $700 billion. In 2018 it was home to the third-highest concentration of Fortune 500 companies in the United States.

The San Francisco Port of Embarkation (SFPOE) was a United States Army command responsible for movement of supplies and troops to and from the Pacific during World War II with extensive facilities in the San Francisco area. SFPOE was established 6 May 1932 and disestablished 1 October 1955. It was originally composed of the long term Pacific terminal at Fort Mason that had been the home port and terminal for the Pacific Army Transport Service ships. That facility was far too limited to serve the requirements of a full port of embarkation. In 1940 the port began expansion to include Army owned and leased facilities throughout the San Francisco Bay area and for a time sub ports at Seattle and Los Angeles. Those eventually became separate commands as the Seattle Port of Embarkation and Los Angeles Port of Embarkation.

Sea transportation was a responsibility of the United States Army Quartermaster Corps but World War II requirements showed weakness in the corps' transportation role. The Army reorganized in March 1942 creating a Transportation Division under the United States Army Services of Supply with a Chief of Transportation. In July the U.S. Army Transportation Corps took over surface transport responsibilities including the ports of embarkation.

Van Ness Avenue is a north–south thoroughfare in San Francisco, California. Originally named Marlette Street, the street was renamed in honor of the city's sixth mayor, James Van Ness.

The main part of Van Ness Avenue runs from Market Street near the Civic Center north to Bay Street at Fort Mason. South Van Ness Avenue is the portion of Van Ness south of Market Street, continuing through the city's South of Market and Mission districts to end at Cesar Chavez Street. This southern segment was formerly a continuation of Howard Street, having been renamed by resolution of the Board of Supervisors on August 22, 1932.

The Panama–Pacific International Exposition was a world's fair held in San Francisco, California, United States, from February 20 to December 4, 1915. Its stated purpose was to celebrate the completion of the Panama Canal, but it was widely seen in the city as an opportunity to showcase its recovery from the 1906 earthquake. The fair was constructed on a 636-acre (257-hectare) site along the northern shore, between the Presidio and Fort Mason, now known as the Marina District.

SS Kronprinzessin Cecilie was an ocean liner built in Stettin, Germany in 1906 for Hapag-Lloyd that had the largest steam reciprocating machinery ever fitted in a ship at the time of construction. The last of four ships of the Kaiser class, she was also the last German ship to have been built with four funnels. She was engaged in transatlantic service between her home port of Bremen and New York until the outbreak of World War I.

On 4 August 1914, at sea after leaving New York, she turned around and put into Bar Harbor, Maine, where she later was interned by the neutral United States. After that country entered the war in April 1917, the ship was seized and turned over to the United States Navy, and renamed USS Mount Vernon (ID-4508). While serving as a troop transport, Mount Vernon was torpedoed in September 1918. Though damaged, she was able to make port for repairs and returned to service. In October 1919 Mount Vernon was turned over for operation by the Army Transport Service in its Pacific fleet based at Fort Mason in San Francisco. USAT Mount Vernon was sent to Vladivostok, Russia to transport elements of the Czechoslovak Legion to Trieste, Italy and German prisoners of war to Hamburg, Germany. On return from that voyage, lasting from March through July 1920, the ship was transferred to the United States Shipping Board and laid up at Solomons Island, Maryland until September 1940 when she was scrapped at Boston, Massachusetts.
