Dr. Charles Caldwell, versatile and voluminous writer of prose, was born at Caswell, North Carolina, May 14, 1772. He entered the medical school of the University of Pennsylvania, in 1792; and he won the city's gratitude in the following year by his medical services during the yellow fever epidemic. In 1810 Dr. Caldwell became professor of natural history in the University of Pennsylvania; and four years later he succeeded Nicholas Biddle (1786-1844) as editor of The Port-Folio, a Philadelphia magazine of high character. In 1819 Dr. Caldwell came to Lexington, Kentucky, to accept the chair of materia medica in Transylvania University. Some months later he was sent to Europe to purchase books and apparatus for his department. He returned to Transylvania and continued there until 1837, when he removed to Louisville and established a medical institute. Some years later he and the trustees disagreed and he left. After leaving the institute, Dr. Caldwell continued to reside at Louisville, in which city he died, July 9, 1853. Dr. Caldwell was the first distinguished American practitioner of phrenology, if he did not actually discover this alleged science. From 1794 until his death, Dr. Caldwell was an indefatigable literary worker. He was the author of more than two hundred pamphlets, essays, and books. He translated Blumenbach's Elements of Physiology (1795); Bachtiar Nameh (1813), a Persian tale which he translated from the Arabic; edited Cullen's Practice of Physic (1816); Memoirs of the Life and Campaigns of the Hon. [General] Greene (Philadelphia, 1819); Elements of Phrenology (1824); A Discourse on the Genius and Character of the Rev. Horace Holley, LL.D., late President of Transylvania University (Boston, 1828); and Thoughts and Experiments on Mesmerism (1842).

Bibliography. His Autobiography (Philadelphia, 1855), published posthumously, has been regarded by many as an unfortunate work, as in it he made some rather severe pictures of his contemporaries. That the work contains much excellent writing, and is often very happy in the descriptions of the country through which the author passed, no one has arisen to gainsay; Autobiography of Samuel D. Gross, M. D. (Philadelphia, 1887, v. ii).

GENERAL GREENE'S EARLY LIFE

[From Memoirs of the Life and Campaigns of the Hon. Nathaniel Greene (Philadelphia, 1819)]

Nathaniel Greene, although descended from ancestors of elevated standing, was not indebted to the condition of his family for any part of the real lustre and reputation he possessed. As truly as is the case with any individual, he was the founder of his own fortune, and the author of his own fame. He was the second son of Nathaniel Greene, an anchor-smith, of considerable note, who is believed to have had the earliest establishment of the kind erected in America, and, by persevering industry in the line of his profession, an extensive and lucrative concern in iron-works, and some success in commercial transactions, had acquired a sufficiency to render him comfortable, if not wealthy.

He was born in the year 1741, in the town of Warwick, and county of Kent, in the province of Rhode Island. As far as is known, his childhood passed without any peculiar or unequivocal indications of future greatness. But this is a point of little moment. The size of the oak it is destined to produce, can rarely be foretold from an examination of the acorn. Nor is it often that any well defined marks of genius in the child afford a premonition of the eminence of the man.

Several of his contemporaries, however, who are still living, have a perfect recollection that young Greene had neither the appearance nor manners of a common boy; nor was he so considered by his elder, and more discerning acquaintance.

Being intended by his father for the business which he had himself pursued, young Greene received at school nothing but the elements of a common English education. But, to himself, an acquisition so humble and limited, was unsatisfactory and mortifying. Even now, his aim was lofty; and he had a noble ambition, not only to embark in high pursuits, but to qualify himself for a manly and honourable acquittance in them. Seeming, at this early period of life, to realize the important truth that, knowledge is power, a desire to obtain it became, in a short time, his ruling passion.

He accordingly procured, in part by his own economy, the necessary books, and, at intervals of leisure, acquired, chiefly without the aid of an instructor, a competent acquaintance with the Latin tongue.

This attainment, respectable in itself, was only preliminary to higher efforts. With such funds as he was able to raise, he purchased a small, but well selected library, and spent his evenings, and all the time he could redeem from business, in regular study. He read with a view to general improvement; but geography, travels, and military history—the latter, more especially—constituted his delight. Having, also, a predilection for mathematics and mechanical philosophy, and pursuing, in most cases, the bent of his inclination, as far as prudence and opportunity would admit, his knowledge, in the more practical departments of these sciences, became highly respectable.
