Sun Tzu (孫子; pinyin: Sūnzǐ) is a honorific title bestowed upon Sūn Wu (孫武 c. 544-496 BC), the author of The Art of War (孫子兵法), an immensely influential ancient Chinese book on military strategy. Sun Tzu believed in the use of the military sciences to effect outcomes that would result in peace. In the author's name, Sūn Wu, the character wu, meaning "military", is the same as the character in wu shu, or martial art. Sun Wu also has a courtesy name, Chang Qing (Cháng Qīng).

Oscar Fingal O'Flahertie Wills Wilde was an Irish playwright, poet, and author of numerous short stories, and one novel. Known for his biting wit, and a plentitude of aphorisms, he became one of the most successful playwrights of the late Victorian era in London, and one of the greatest celebrities of his day. Several of his plays continue to be widely performed, especially The Importance of Being Earnest. As the result of a widely covered series of trials, Wilde suffered a dramatic downfall and was imprisoned for two years hard labour after being convicted of "gross indecency" with other men. After Wilde was released from prison he set sail for Dieppe by the night ferry. He never returned to Ireland or Britain, and died in poverty.

Marcus Aurelius Antoninus Augustus (often referred to as "the wise") was Emperor of the Roman Empire from 161 to his death in 180. He was the last of the "Five Good Emperors", and is also considered one of the more important Stoic philosophers. His two decades as emperor were marked by near continual warfare. He was faced with a series of invasions from German tribes, and by conflicts with the Parthian Empire in the east. His reign also had to deal with an internal revolt in the east, led by Avidius Cassius. Marcus Aurelius' work Meditations, written in Greek while on campaign between 170 and 180, is still revered as a literary monument to a government of service and duty and has been praised for its "exquisite accent and its infinite tenderness."

Kahlil Gibran (Arabic: جبران خليل جبران ) was a Lebanese-American artist, poet, and writer. Born in the town of Bsharri in modern-day Lebanon (then part of Ottoman Mount Lebanon), as a young man he emigrated with his family to the United States where he studied art and began his literary career. In the Arab world, Gibran is regarded as a literary and political rebel. His romantic style was at the heart of a renaissance in modern Arabic literature, especially prose poetry, breaking away from the classical school. In Lebanon, he is still celebrated as a literary hero. He is chiefly known in the English-speaking world for his 1923 book The Prophet, an early example of inspirational fiction including a series of philosophical essays written in poetic English prose. The book sold well despite a cool critical reception, gaining popularity in the 1930s and again, especially in the 1960s counterculture. Gibran is the third best-selling poet of all time, behind Shakespeare and Lao-Tzu.

John Griffith Chaney (1876-1916), better known as Jack London, was an American novelist, journalist, and social activist. A pioneer of commercial fiction and American magazines, he was one of the first American authors to become an international celebrity and earn a large fortune from writing. He was also an innovator in the genre that would later become known as science fiction. His most famous works include The Call of the Wild and White Fang, both set in the Klondike Gold Rush, as well as the short stories, "To Build a Fire", "An Odyssey of the North", and "Love of Life". He also wrote about the South Pacific in stories such as "The Pearls of Parlay", and "The Heathen". London was part of the radical literary group, "The Crowd," in San Francisco and a passionate advocate of unionization, workers' rights, and socialism. He wrote several works dealing with these topics, such as his dystopian novel, The Iron Heel, his non-fiction exposé The People of the Abyss, War of the Classes, and Before Adam. London died November 22, 1916, in a sleeping porch in a cottage on his ranch. London's ashes were buried on his property, not far from the Wolf House. The grave is marked by a mossy boulder. The buildings and property were later preserved as Jack London State Historic Park, in Glen Ellen, California.
