A private island is a disconnected body of land wholly owned by a single private citizen or corporation. Although this exclusivity gives the owner substantial control over the property, they still fall within the jurisdiction of national and sometimes local governments.

The benefit and disadvantage of an island property instead of property on the continent is that access is much more restricted, both from potential trespassers, but also from the owner, who needs to transport all supplies by boat or aircraft. Livestock has often been kept on islands, because an island is a natural enclosure, preventing the escape of cattle and sheep.

There are many thousands of uninhabited islands in the world with potential for commercial development of tourist resorts or private recreational use. Commercial development of uninhabited islands can bring up ecological concerns, as many have a fragile environment. Some islands can be bought undeveloped, while other include roads and/or houses. Islands are also available for rent. Some celebrities have their own private islands.

Frank Lloyd Wright (born Frank Lincoln Wright, June 8, 1867 – April 9, 1959) was an American architect, interior designer, writer and educator, who designed more than 1,000 structures and completed 500 works. Wright believed in designing structures which were in harmony with humanity and its environment, a philosophy he called organic architecture. This philosophy was best exemplified by his design for Fallingwater (1935), which has been called "the best all-time work of American architecture". Wright was a leader of the Prairie School movement of architecture and developed the concept of the Usonian home, his unique vision for urban planning in the United States.

His work includes original and innovative examples of many different building types, including offices, churches, schools, skyscrapers, hotels, and museums. Wright also designed many of the interior elements of his buildings, such as the furniture and stained glass. Wright authored 20 books and many articles and was a popular lecturer in the United States and in Europe. His colorful personal life often made headlines, most notably for the 1914 fire and murders at his Taliesin studio. Already well known during his lifetime, Wright was recognized in 1991 by the American Institute of Architects as "the greatest American architect of all time."

Marlon Brando, Jr. (April 3, 1924 – July 1, 2004) was an American movie star and political activist. "Unchallenged as the most important actor in modern American Cinema" according to the St. James Encyclopedia of Popular Culture, Brando was one of only three professional actors, along with Charlie Chaplin and Marilyn Monroe, named by Time magazine as one of its 100 Persons of the Century in 1999.

Brando had a significant impact on film acting, and was the foremost example of the "method" acting style. While he became notorious for his "mumbling" diction and exuding a raw animal magnetism, his mercurial performances were nonetheless highly regarded, and he is widely considered as one of the greatest and most influential actors of the 20th century. Director Martin Scorsese said of him, "He is the marker. There's 'before Brando' and 'after Brando'." Actor Jack Nicholson once said, "When Marlon dies, everybody moves up one." He was ranked by the American Film Institute as the fourth greatest screen legend among male movie stars.
