Question: When did Brett Weston's place of death become part of the United States?

full_context: Document 1: Hawaiian Islands: The Hawaiian Islands (Hawaiian: Mokupuni o Hawai'i) are an archipelago of eight major islands, several atolls, numerous smaller islets, and seamounts in the North Pacific Ocean, extending some 1,500 miles (2,400 kilometers) from the island of Hawai ʻi in the south to northernmost Kure Atoll. Formerly the group was known to Europeans and Americans as the ``Sandwich Islands '', a name chosen by James Cook in honor of the then First Lord of the Admiralty John Montagu, 4th Earl of Sandwich. The contemporary name is derived from the name of the largest island, Hawaii Island.
Document 2: Pepper No. 30: Pepper No. 30 is one of the best-known photographs taken by Edward Weston. It depicts a solitary green pepper in rich black-and-white tones, with strong illumination from above.
Document 3: Film speed: Before the advent of the ASA system, the system of Weston film speed ratings was introduced by Edward Faraday Weston (1878–1971) and his father Dr. Edward Weston (1850–1936), a British-born electrical engineer, industrialist and founder of the US-based Weston Electrical Instrument Corporation, with the Weston model 617, one of the earliest photo-electric exposure meters, in August 1932. The meter and film rating system were invented by William Nelson Goodwin, Jr., who worked for them and later received a Howard N. Potts Medal for his contributions to engineering.
Document 4: Minor White: Minor Martin White (July 9, 1908 – June 24, 1976) was an American photographer, theoretician, critic and educator. He combined an intense interest in how people viewed and understood photographs with a personal vision that was guided by a variety of spiritual and intellectual philosophies. Starting in Oregon in 1937 and continuing until he died in 1976, White made thousands of black-and-white and color photographs of landscapes, people and abstract subject matter, created with both technical mastery and a strong visual sense of light and shadow. He taught many classes, workshops and retreats on photography at the California School of Fine Arts, Rochester Institute of Technology, Massachusetts Institute of Technology, other schools, and in his own home. He lived much of his life as a closeted gay man, afraid to express himself publicly for fear of loss of his teaching jobs, and some of his most compelling images are figure studies of men whom he taught or with whom he had relationships. He helped start and for many years was editor of the photography magazine "Aperture". After his death in 1976, White was hailed as one of America's greatest photographers.
Document 5: Bliss (image): Former National Geographic photographer Charles O'Rear, a resident of the nearby Napa Valley, took the photo on film with a medium - format Mamiya RZ67 camera while on his way to visit his girlfriend in 1996. While it was widely believed later that the image was digitally manipulated or even created with software such as Adobe Photoshop, O'Rear says it never was. He sold it to Corbis for use as a stock photo. Several years later, Microsoft engineers chose a digitized version of the image and licensed it from O'Rear.
Document 6: History of Hawaii: The native population succumbed to disease brought by the Europeans (particularly smallpox), declining from 300,000 in the 1770s over 60,000 in the 1850s to 24,000 in 1920. Americans within the kingdom government rewrote the constitution, severely curtailing the power of King ``David ''Kalākaua, and disenfranchising the rights of most Native Hawaiians and Asian citizens to vote, through excessively high property and income requirements. This gave a sizeable advantage to plantation owners. Queen Liliuokalani attempted to restore royal powers in 1893, but was placed under house arrest by businessmen with help from the US military. Against the Queen's wishes, the Republic of Hawaii was formed for a short time. This government agreed on behalf of Hawaii to join the US in 1898 as the Territory of Hawaii. In 1959, the islands became the state of Hawaii of the United States.
Document 7: 51st state: Cuba, like many Spanish territories, wanted to break free from Spain. A pro-independence movement in Cuba was supported by the U.S., and Cuban guerrilla leaders wanted annexation to the United States, but Cuban revolutionary leader José Martí called for Cuban nationhood. When the U.S. battleship Maine sank in Havana Harbor, the U.S. blamed Spain and the Spanish–American War broke out in 1898. After the U.S. won, Spain relinquished claim of sovereignty over territories, including Cuba. The U.S. administered Cuba as a protectorate until 1902. Several decades later in 1959, the corrupt Cuban government of U.S.-backed Fulgencio Batista was overthrown by Fidel Castro. Castro installed a Marxist–Leninist government allied with the Soviet Union, which has been in power ever since.
Document 8: Hawaii: Hawaii (English: / həˈwaɪ. i, - ji, - ʔi / (listen) hə - WY - (y) ee; Hawaiian: Hawai ʻi (həˈvɐjʔi)) is the 50th and most recent state to have joined the United States of America, having received statehood on August 21, 1959. Hawaii is the only U.S. state located in Oceania and the only one composed entirely of islands. It is the northernmost island group in Polynesia, occupying most of an archipelago in the central Pacific Ocean. Hawaii is the only U.S. state located outside North America.
Document 9: Brett Weston: Theodore Brett Weston (December 16, 1911, Los Angeles – January 22, 1993, Hawaii) was an American photographer.

Document 11: Dody Weston Thompson: Dody Weston Thompson (April 11, 1923 – October 14, 2012) was a 20th-century American photographer and chronicler of the history and craft of photography. She learned the art in 1947 and developed her own expression of “straight” or realistic photography, the style that emerged in Northern California in the 1930s. Dody worked closely with contemporary icons Edward Weston (her former father-in-law), Brett Weston (her former husband) and Ansel Adams (as an assistant and a friend) during the late 1940s and through the 1950s, with additional collaboration with Brett Weston in the 1980s.
Document 12: Hawaii: The Kingdom of Hawai ʻi was sovereign from 1810 until 1893 when the monarchy was overthrown by resident American and European capitalists and landholders. Hawaii was an independent republic from 1894 until August 12, 1898, when it officially became a territory of the United States. Hawaii was admitted as a U.S. state on August 21, 1959.
Document 13: Overthrow of the Hawaiian Kingdom: The overthrow of the Kingdom of Hawaii began on January 17, 1893, with a coup d'état against Queen Liliuokalani on the island of Oahu by foreign residents residing in Honolulu, mostly United States citizens, and subjects of the Kingdom of Hawaii. They prevailed upon American minister John L. Stevens to call in the U.S. Marines to protect American interests, an action that effectively buttressed the rebellion. The revolutionaries established the Republic of Hawaii, but their ultimate goal was the annexation of the islands to the United States, which finally occurred in 1898.
Document 14: Scot Sothern: Scot Sothern (born 1949) is an American photographer and writer best known for his controversial black and white photographs of prostitutes in Southern California, whom he photographed from 1986 to 1990, and again in 2010 when he began photograph and writing about sex workers in Los Angeles Skid Row. Sothern says the photographs are exposés, but they don't just expose the women in them, they expose the artist behind the camera. "They show that I am who they are."
Document 15: Honolulu: In 1845, Kamehameha III moved the permanent capital of the Hawaiian Kingdom from Lahaina on Maui to Honolulu. He and the kings that followed him transformed Honolulu into a modern capital, erecting buildings such as St. Andrew's Cathedral, ʻIolani Palace, and Ali ʻiōlani Hale. At the same time, Honolulu became the center of commerce in the islands, with descendants of American missionaries establishing major businesses in downtown Honolulu.
