William Blake was born in London in 1757. He was apprenticed to a master engraver and then studied at the Royal Academy under the guidance of Joshua Reynolds. In 1789 he engraved and published Songs of Innocence and the contrasting Songs of Experience came later in 1794. A poet, painter and printmaker of great originality and imagination, his work was largely unrecognized during his lifetime and he struggled to make a living. Blake is now considered a seminal figure in the history of both the poetry and visual arts of the Romantic Age. He died in 1827.

Poet, philosopher and artist, Kahlil Gibran was born near Mount Lebanon.

His many works include The Prophet, his masterpiece of religious inspiration; The Garden of the Prophet; The Storm: Stories and Prose Poems; The Beloved: Reflections on the Path of the Heart; Jesus: The Son of Man; The Voice of Kahlil Gibran, an anthology of his writings; The Vision: Reflections on the Way of the Soul; and Spirit Brides.

Ralph Waldo Emerson (May 25, 1803-April 27, 1882) was a famous lecturer, philosopher, poet, and writer. He led the transcendentalist movement of the 1800s, mentored Henry David Thoreau, and was a pioneer of multiculturalism in American writing.

Charles H. Spurgeon (1834-1892) was a British Baptist preacher who remains highly influential among Christians of different denominations, among whom he is still known as the "Prince of Preachers." He preached his first sermon, from 1 Peter 2:7, in 1851 at 16 and became pastor of the Church in Waterbeach in 1852. He published more than 1,900 different sermons and preached to around 10,000,000 people during his lifetime.

In addition, Spurgeon was a prolific author of many types of works including an autobiography, a commentary, books on prayer, a devotional, a magazine, poetry, hymnist and more. Many sermons were transcribed as he spoke and were later translated into many languages. Arguably, no other author, Christian or otherwise, has more material in print than C.H. Spurgeon.

The brilliant Russian novelist Fyodor Dostoyevsky (1821–81) is celebrated for such classics as Crime and Punishment and The Brothers Karamazov whose psychological examinations of the human soul had a profound effect on the 20th-century novel.
