James Gates Percival was a precocious child and a versatile, yet morbid and impractical man. He had a remarkable ability to write verse on various subjects and in almost every known meter. His sentimentalism and dazzling diction appealed to a wide audience, earning him a reputation as the foremost poet in the United States during the 1820s. Some of his most famous poems include "Prometheus," "The Coral Grove," and "The Graves of the Patriots." He was also a renowned geologist.

Percival entered Yale College at the age of 16 and graduated at the head of his class at the age of 20. After graduating, he pursued a career in medicine and relocated to Charleston, South Carolina. In 1823, a volume of his collected poems was published in New York and London.^[4] In 1824, he briefly served as a professor of chemistry at West Point before resigning and dedicating several years to assisting Noah Webster in editing his American Dictionary of the English Language, published in 1828.

In 1835, the governor of Connecticut commissioned Percival to prepare a geological survey of the state, which he completed and published in 1842. In 1854, he was appointed as the State Geologist for Wisconsin and tasked with conducting a similar geological survey. The first annual report was issued in 1855, but while preparing the second annual report, Percival fell ill and passed away in May 1856. Most of his life was spent at his home in New Haven, Connecticut. Following his death, he was the subject of an admiring biography by Julius H. Ward.
