Evelyn Underhill (6 December 1875 – 15 June 1941) was an English Anglo-Catholic writer and pacifist known for her numerous works on religion and spiritual practice, in particular Christian mysticism.

In the English-speaking world, she was one of the most widely read writers on such matters in the first half of the twentieth century. No other book of its type—until the appearance in 1946 of Aldous Huxley's The Perennial Philosophy—met with success to match that of her best-known work, Mysticism, published in 1911.

Underhill was born in Wolverhampton. She was a poet and novelist, as well as being a pacifist and mystic. An only child, her early mystical insights she described as "abrupt experiences of the peaceful, undifferentiated plane of reality—like the "still desert" of the mystic—in which there was no multiplicity nor need of explanation." The meaning of these experiences became a lifelong quest and source of private angst, provoking her to research and write.

Both her father and her husband were writers (on the law), London barristers and yachtsmen. She and her husband, Hubert Stuart Moore, grew up together and were married on 3 July 1907. The couple had no children. She travelled regularly within Europe, primarily Switzerland, France and Italy where she pursued her interests in art and Catholicism, visiting numerous churches and monasteries. Neither her husband (a Protestant) nor her parents shared her interest in spiritual matters.

William Blake (28 November 1757 – 12 August 1827) was an English poet, painter, and printmaker. Largely unrecognised during his lifetime, Blake is now considered a seminal figure in the history of both the poetry and visual arts of the Romantic Age. His prophetic poetry has been said to form "what is in proportion to its merits the least read body of poetry in the English language". His visual artistry has led one contemporary art critic to proclaim him "far and away the greatest artist Britain has ever produced". Although he lived in London his entire life except for three years spent in Felpham he produced a diverse and symbolically rich corpus, which embraced the imagination as "the body of God", or "Human existence itself".

Considered mad by contemporaries for his idiosyncratic views, Blake is held in high regard by later critics for his expressiveness and creativity, and for the philosophical and mystical undercurrents within his work. His paintings and poetry have been characterised as part of both the Romantic movement and "Pre-Romantic", for its large appearance in the 18th century. Reverent of the Bible but hostile to the Church of England – indeed, to all forms of organised religion – Blake was influenced by the ideals and ambitions of the French and American revolutions, as well as by such thinkers as Jakob Böhme and Emanuel Swedenborg. Despite these known influences, the singularity of Blake's work makes him difficult to classify. The 19th-century scholar William Rossetti characterised Blake as a "glorious luminary," and as "a man not forestalled by predecessors, nor to be classed with contemporaries, nor to be replaced by known or readily surmisable successors".

Walter Elias "Walt" Disney (December 5, 1901 – December 15, 1966) was an American film producer, director, screenwriter, voice actor, animator, entrepreneur, entertainer, international icon, and philanthropist, well known for his influence in the field of entertainment during the 20th century. Along with his brother Roy O. Disney, he was co-founder of Walt Disney Productions, which later became one of the best-known motion picture producers in the world. The corporation is now known as The Walt Disney Company and had an annual revenue of approximately US$36 billion in the 2010 financial year.

Disney is particularly noted as a film producer and a popular showman, as well as an innovator in animation and theme park design. He and his staff created some of the world's most well-known fictional characters including Mickey Mouse, for whom Disney himself provided the original voice. During his lifetime he received four honorary Academy Awards and won 22 Academy Awards from a total of 59 nominations, including a record four in one year, giving him more awards and nominations than any other individual in history. Disney also won seven Emmy Awards and gave his name to the Disneyland and Walt Disney World Resort theme parks in the U.S., as well as the international resorts Tokyo Disney Resort, Disneyland Paris, and Hong Kong Disneyland.
