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.

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.

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.
