Samuel Prescott Hildreth
Samuel Prescott Hildreth (1783–1863) was a pioneer physician, scientist, and historian, authoring numerous scientific and historical works. His history books are largely based on first-person accounts and primary documents, providing insight into the early settlement of Marietta, Ohio, and the Northwest Territory and the lives of early pioneers.

Early life
Samuel Prescott Hildreth was born in Methuen, Massachusetts, on September 30, 1783. His father, Dr. Samuel Hildreth of Massachusetts, was a physician with a regiment of volunteers during the American Revolutionary War, served as surgeon aboard a privateer, and became  a prisoner-of-war. Samuel Prescott Hildreth was educated at the Phillips Academy at Andover, Massachusetts. He began medical studies under his father, completed studies under care of Dr. Thomas Kittredge of Andover, and received his diploma in 1805 after examination by the Massachusetts Medical Society. He subsequently practiced medicine in Hampstead, New Hampshire, until relocating to Ohio in 1806.

Massachusetts to Ohio
His father, Samuel Hildreth, was a shareholder in the Ohio Company of Associates, and had considered moving to Ohio. Since he was a boy, Samuel Prescott Hildreth had a desire to see the Ohio Country; he acted on his desire at the age of 23, traveling by horseback to Marietta, Ohio, during September and October 1806. He spent about nine weeks in Marietta, then traveled 15 miles down the Ohio River to Belpre, Ohio. In August 1807 he married Ms. Rhoda Cook in Belpre. They permanently resettled to Marietta in March 1808. Subsequently, during 1810 and 1811, Dr. Samuel Prescott Hildreth served on the Ohio legislature. His father, Dr. Samuel Hildreth of Massachusetts, died while visiting him in Ohio during 1823 and was buried at Mound Cemetery in Marietta.

Career
In Marietta, Dr. Samuel Prescott Hildreth served as the town's doctor and pursued the study of local history, botany, and geology. Dr. Hildreth was noted as one of the first pioneers of science in the country west of the Alleghany Mountains. He exhibited "a remarkable genius in drawing. Insects and plants were represented with scrupulous accuracy, and engravings made from them have a permanent value". "Dr. Hildreth was distinguished for his industrious research, and his numerous and well-received publications on professional topics; on natural history; on the antiquities, the modern history, and the resources, of his Western home." In addition to serving in the Ohio legislature, he also served on the Ohio Geologic Survey. Dr. Samuel Prescott Hildreth died in Marietta, Ohio, on July 24, 1863, and was buried at Mound Cemetery in Marietta, along with his father and with many Revolutionary War soldiers and founding pioneer settlers of Marietta and the Northwest Territory.

Scientific publications
Dr. Hildreth was the author of numerous scientific publications. He was industrious, and provided many valuable contributions to medical journals from 1808 to 1825.

"In 1808 he published in the New York Medical Repository, a history of an epidemic which had prevailed the previous year; also in 1812 a description of the American Colomba, with a figure of the plant; likewise in 1822, an article on Hydrophobia, and another on a curious case of Siamese twins, in his practice. In 1824 he published in the Philadelphia Journal of Medical Science, a full history of the Great Epidemic Fever that visited the Ohio Valley and Marietta in 1822 and 1823; and in 1825, in the Western Journal of Medicine, Cincinnati, an account of the minor diseases of the epidemic. In 1826, he published in Silliman's Journal of Science, New Haven, a series of articles on the Natural and Civil History of Washington County. From that time until his death, nearly forty years, he was a contributor to the Journal—such articles as descriptions and drawings of fresh-water shells found in the Muskingum and other streams, several upon geological subjects, touching upon the geology of Southeastern Ohio, the salt-bearing rock, the history of salt manufacture from the first settlement of Ohio, the coal formation, &c."<ref name = "Medical News">Medical News and Library, Vol. XXI, No. 249, September 1863".</ref>

The first volume of Archaeologia Americana, published in 1820, contains important letters on objects of antiquarian interest in the vicinity of Marietta, Ohio, from Dr. Hildreth; and soon after he made repeated contributions to the American Antiquarian Society relating to kindred subjects.

He presented his scientific library and his collections in various departments of natural history, numbering about 4000 specimens, to Marietta College, Ohio, where they occupied a room known as the Hildreth Cabinet, and his manuscripts are known as the Samuel P. Hildreth Collection.
