Janet Miriam Caldwell (September 7, 1900 – August 30, 1985) was a British-born American novelist and prolific author of popular fiction under the pen names Taylor Caldwell, Marcus Holland and Max Reiner. She was also known by a variation of her married name, J. Miriam Reback.

In her fiction, she often used real historical events or persons. Taylor Caldwell's best-known works include Dynasty of Death, Dear and Glorious Physician (about Saint Luke), Ceremony of the Innocent, Pillar of Iron (about Cicero), The Earth is the Lord's (about Genghis Khan) and Captains and the Kings. Her last major novel, Answer As a Man, appeared in 1980.

Also known by the pen names Marcus Holland and Max Reiner. Taylor Caldwell was born in Manchester, England. In 1907 she emigrated to the United States with her parents and younger brother. Her father died shortly after the move, and the family struggled. At the age of eight she started to write stories, and in fact wrote her first novel, The Romance of Atlantis, at the age of twelve (although it remained unpublished until 1975). Her father did not approve such activity for women, and sent her to work in a bindery. She continued to write prolifically, however, despite ill health. In 1918-1919, she served in the United States Navy Reserve.
