Dr. Heidegger's Experiment is a short story by Nathaniel Hawthorne (born Nathaniel Hathorne; July 4, 1804 - May 19, 1864) was an American novelist and short story writer. He was born in 1804 in Salem, Massachusetts to Nathaniel Hathorne and the former Elizabeth Clarke Manning. His ancestors include John Hathorne, the only judge involved in the Salem witch trials who never repented of his actions. Nathaniel later added a "w" to make his name "Hawthorne" in order to hide this relation. He entered Bowdoin College in 1821, was elected to Phi Beta Kappa in 1824, and graduated in 1825. Hawthorne published his first work, a novel titled Fanshawe, in 1828; he later tried to suppress it, feeling it was not equal to the standard of his later work. He published several short stories in various periodicals which he collected in 1837 as Twice-Told Tales. The next year, he became engaged to Sophia Peabody. He worked at a Custom House and joined Brook Farm, a transcendentalist community, before marrying Peabody in 1842. The couple moved to The Old Manse in Concord, Massachusetts, later moving to Salem, the Berkshires, then to The Wayside in Concord. The Scarlet Letter was published in 1850, followed by a succession of other novels. A political appointment took Hawthorne and family to Europe before their return to The Wayside in 1860. Hawthorne died on May 19, 1864, and was survived by his wife and their three children. Much of Hawthorne's writing centers on New England, many works featuring moral allegories with a Puritan inspiration. His fiction works are considered part of the Romantic movement and, more specifically, Dark romanticism. His themes often center on the inherent evil and sin of humanity, and his works often have moral messages and deep psychological complexity. His published works include novels, short stories, and a biography of his friend Franklin Pierce. Hawthorne's works belong to romanticism or, more specifically, dark romanticism, cautionary tales that suggest that guilt, sin, and evil are the most inherent natural qualities of humanity. Many of his works are inspired by Puritan New England, combining historical romance loaded with symbolism and deep psychological themes, bordering on surrealism. His depictions of the past are a version of historical fiction used only as a vehicle to express common themes of ancestral sin, guilt and retribution. His later writings also reflect his negative view of the Transcendentalism movement. Hawthorne was predominantly a short story writer in his early career. Upon publishing Twice-Told Tales, however, he noted, "I do not think much of them," and he expected little response from the public. His four major romances were written between 1850 and 1860: The Scarlet Letter (1850), The House of the Seven Gables (1851), The Blithedale Romance' (1852) and The Marble Faun (1860). Another novel-length romance, Fanshawe was published anonymously in 1828. Hawthorne defined a romance as being radically different from a novel by not being concerned with the possible or probable course of ordinary experience. In the preface to The House of the Seven Gables, Hawthorne describes his romance-writing as using "atmospherical medium as to bring out or mellow the lights and deepen and enrich the shadows of the picture."
