Florence Scovel Shinn carried out her work in the first half of the 20th century.

James Allen was born in Leicester, England, in 1864. He took his first job at age 15 to support his family, after his father was murdered while looking for work in America. Allen was employed as a factory knitter and a private secretary until the early 1900s, when he became increasingly known for his motivational writing.

His 1903 work As a Man Thinketh earned him worldwide fame as a prophet of inspirational thinking and influenced a who's-who of self-help writers, including Napoleon Hill.

Not much is known about the legendary LAO TZU, to whom authorship of the TAO TEH CHING is popularly attributed. Some scholars believe the author was an elder contemporary of Confucius.

Marcus Aurelius Antoninus was born in AD 121, in the reign of the emperor Hadrian. At first he was called Marcus Annius Verus, but his well-born father died young and he was adopted, first by his grandfather, who had him educated by a number of excellent tutors, and then, when he was sixteen, by Aurelius Antoninus, his uncle by marriage, who had been adopted as Hadrian's heir, and had no surviving sons of his own. Aurelius Antoninus changed Marcus' name to his own and betrothed him to his daughter, Faustina. She bore fourteen children, but none of the sons survived Marcus except the worthless Commodus, who eventually succeeded Marcus as emperor.

On the death of Antoninus in 161, Marcus made Lucius Verus, another adopted son of his uncle, his colleague in government. There were thus two emperors ruling jointly for the first time in Roman history. The Empire then entered a period troubled by natural disasters, famine, plague and floods, and by invasions of barbarians. In 168, one year before the death of Verus left him in sole command, Marcus went to join his legions on the Danube.

Apart from a brief visit to Asia to crush the revolt of Avidius Cassius, whose followers he treated with clemency, Marcus stayed in the Danube region and consoled his somewhat melancholy life there by writing a series of reflections which he called simply To Himself. These are now known as his Meditations, and they reveal a mind of great humanity and natural humility, formed in the Stoic tradition, which has long been admired in the Christian world. He died, of an infectious disease, perhaps, in camp on 17 March AD 180.

Napoleon Hill was born in 1883 in a one-room cabin on the Pound River in Wise County, Virginia. He began his writing career at age 13 as a "mountain reporter" for small town newspapers and went on to become America's most beloved motivational author.

Hill passed away in November 1970 after a long and successful career writing, teaching, and lecturing about the principles of success. Dr. Hill's work stands as a monument to individual achievement and is the cornerstone of modern motivation. His book, Think and Grow Rich, is the all-time bestseller in the field.

Hill established the Foundation as a nonprofit educational institution whose mission is to perpetuate his philosophy of leadership, self-motivation, and individual achievement.

His books, audio cassettes, videotapes, and other motivational products are made available to you as a service of the Foundation so that you may build your own library of personal achievement materials...and help you acquire financial wealth and the true riches of life.

Sun Tzu is a honorific title bestowed upon Sūn Wu (c. 544-496 BC), the author of The Art of War, an immensely influential ancient Chinese book on military strategy.

He is also one of the earliest realists in international relations theory. 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).

Wallace D. Wattles (1860-1911) was the author of numerous books, the best known of which is The Science of Getting Rich.

He died a prosperous man in 1911.
