Solomon Spalding (February 20, 1761 – October 20, 1816) was the author of two related texts: an unfinished manuscript entitled Manuscript Story – Conneaut Creek, and an unpublished historical romance about the lost civilization of the mound builders of North America called Manuscript, Found. Whether these texts are distinct is disputed. After Spalding's death, a number of individuals suggested that Spalding's work was used as a source for the Book of Mormon, a scripture in the Latter Day Saint movement.
Spalding was born in Ashford, Connecticut. He was a member of the Continental Army during the American Revolutionary War. In 1782, he entered Dartmouth College in Hanover, New Hampshire, graduating with the class of 1785. In October 1787, he became an ordained Congregationalist preacher in Windham, Connecticut.
In 1795, Spalding married Matilda Sabin and opened a store with his brother Josiah in Cherry Valley, New York. In 1799, they moved the store to Richfield, New York. Around this time, Spalding bought a tract of land in and relocated to Conneaut, Ohio. While in Conneaut, Spalding began writing Manuscript, Found. In 1812, due to the disruptions of the War of 1812, Spalding moved to Pittsburgh, Pennsylvania. In 1814, he moved to Amity, Pennsylvania, where he died two years later.
From 1809 to 1812, Spalding worked on a historical fiction about a Roman discovery of the Americas. An unfinished manuscript copy of this work exists, called "The Oberlin Manuscript" or "Honolulu Manuscript". It is a historical romance "purporting to have been translated from the Latin, found on 24 rolls of parchment in a cave, on the banks of the Conneaut Creek". It tells of a Roman ship which discovers America.
