Charles Lucian Bonaparte was a naturalist and ornithologist.

From the guide to the Correspondence, 1824-1855, from American scientists, 1824-1855, (American Philosophical Society)

Hare was prof. of chemistry at the University of Pennsylvania Medical School, invented the oxyhydrogen blowpipe and built other apparatus for research. His own apparatus was displayed at the Franklin Institute before being given to the Smithsonian Institution. Author of over 100 articles and translator of works by Berzelius and others, he was a member of the American Philosophical Society.

Robert Hare was a chemist and inventor and taught at the University of Pennsylvania.

Robert Hare (1781-1858, APS 1803) was a chemist best known as an experimentalist and an innovator in the production of chemical apparatus. His inventions include the calorimeter, the deflagrator, and, most significantly, the oxyhydrogen blowtorch. He was Professor of Chemistry at the University of Pennsylvania for nearly three decades. Toward the end of his life Hare was an outspoken supporter of Spiritualism.

Robert Hare recalled being dandled on the knee of George Washington, an event that seems to have remained in his mind as he grew older, tying him to the fate of his nation and to his position on the privileged end of the social hierarchy. Hare was born in Philadelphia in 1781, the son of Robert Hare, Sr., a major Philadelphia brewer, and Margaret Willing niece, of Thomas Willing, the political leader and president of the Bank of North America.

Hare evidently demonstrated an interest in chemistry from an early age. As a young man, he attended the Academy of the University of Pennsylvania. Possessed of an innate mechanical aptitude, Hare developed a passion for chemistry while attending the lectures of James Woodhouse (1770-1809, APS 1796), and in later years the pairing of instrumental and intellectual prowess made him one of the foremost chemical experimentalists and technical innovators in the nation. Hare was a junior member of the Philadelphia Chemical Society, where his associates and teachers, in addition to Woodhouse, were Joseph Priestley (1733-1804, APS 1785) and the mineralogist Adam Seybert (1773-1825, APS 1797).

Before he turned 20, Hare had begun to experiment toward a method of generating higher temperatures than possible in contemporary furnaces, adapting a keg from his father's brewery to develop an instrument he called the hydrostatic blow-pipe - the oxyhydrogen blowtorch. The blow-pipe proved invaluable in fusing previously infusable metals such as platinum, and, when used by Thomas Drummond to ignite calcium hydroxide, it was found to produce a remarkably bright light that became the preferred medium for lighthouses and the stage, called limelight. The small pamphlet that Hare wrote to describe his invention, Memoir on the Supply and Application of the Blow-Pipe... (1802), brought him international renown when it was republished in the prestigious English Philosophical Magazine and the French Annales de Chimie . He also described his findings in the annual address to the Chemical Society in 1801. Largely on the strength of this single invention, Hare was elected to the American Philosophical Society in 1803 and was awarded an honorary medical degree by Yale in 1806. The discovery subsequently made him the first recipient of the American Academy of Arts and Sciences’ Rumford Medal in 1839.

Still barely in his majority, Hare continued to work for his father's brewery, devising new, tighter kegs and a modified stop cock. In 1802 he made the acquaintance Benjamin Silliman (1779-1864, APS 1805), Professor of Chemistry and Natural Philosophy at Yale, who had come to Philadelphia to hear the lectures of Woodhouse, Benjamin Smith Barton (1766-1815, APS 1759), and Caspar Wistar (1761-1818, APS 1787). Hare and Silliman conducted scientific experiments during this and subsequent visits by Silliman; they remained lifelong friends and correspondents.

In 1809, the availability of the chair in chemistry at the University of Pennsylvania vacated by the death of Joseph Woodward opened an opportunity for Hare to turn his full attention to the subject he loved. After he was denied the appointment for lack of a medical degree, Benjamin Rush (1745-1813, APS 1768) intervened to persuade the trustees to create a new position in the Medical School in Natural Philosophy. In 1810 Hare accepted the position, but since his course was listed only as an elective, he had few matriculants, and resigned two years later due to the lack of remuneration.

In 1811 Hare married Harriet Clark, daughter of the merchant John Innes Clark and his wife Lydia Bowen.

Hare returned to his father's brewery, where he entered into a bleak period. Assuming full managerial responsibilities for the brewery following his father's death, Hare ran into financial ruin during the economic chaos of the War of 1812. His efforts to make a living at selling gases and running a druggist's concern in Providence, Rhode Island (where his wife's family resided), were unavailing. His fortunes changed in 1818, when the College of William and Mary offered him a position as Professor of Natural Philosophy and later that same year, when the Medical School at University of Pennsylvania appointed him as Professor of Chemistry. He returned to Philadelphia and remained at the University of Pennsylvania for almost thirty years. Among the many students he worked with Hare during this period were Samuel H. Stout (1822-1903) and Joseph Leidy (1823-1891, APS 1849).

As an instructor, Hare was at his best with advanced students but was generally appreciated for his dramatic demonstrations of chemical principles, often employing apparatus he had developed himself. His Compendium of the Course of Chemical Instruction (1828) went through at least four editions before 1840, and is considered one of the most thorough chemical textbooks in antebellum America. Although he taught chemistry to a large number of medical students, his greatest contributions to his field were as an experimentalist and an innovator in the production of chemical apparatus. Among his most important inventions were the calorimeter (1819), the deflagrator (1821) for producing powerful electrical currents, the litrameter for measuring the specific gravity of fluids, a hydrostatic balance, a cryophorus, and a gas density balance. He was also responsible for isolating elemental boron and silicon, becoming the first American to produce metallic calcium, and was an active researcher in electrical theory and the devising of electrical apparatus. He donated his equipment to the fledgling Smithsonian Institution in 1849, only to have them destroyed by fire years later.

Hare, however, was never only a chemist. He wrote poetry and fiction, including Standish the Puritan (1850), and Overling; or, The Heir of Wycherly (1852), and was a diehard, politically conservative controversialist, describing himself as a "Washington Federalist" well into the 1850s. Beginning with his Defence of the American Character, or, An Essay on Wealth as an Object of Cupidity or the Means of Distinction in the United States (1819), a work that first appeared in the Federalist Port Folio, Hare wrote frequently on banking, finance, currency, tariff, and social order, almost always assailing those principles he identified as "Jeffersonian" or as leading to social-leveling.

Hare was not loath to participate in discussions of the major social issues of his day, including the abolition of slavery and the clash between capital and labor. A firm believer in social hierarchy, he considered himself an antislavery man, though advocating that freed slaves be relegated to a circumscribed subordinate status in American society and compensating slave owners for any losses they incurred. Importing freedmen to the north, he reasoned, would be beneficial to the former slaves - enabling them to be in closer contact with greater numbers of whites - but also financially beneficial to the northern community as a steady supply of cheap labor. A fear of servile insurrection - creating the grounds for another Haiti - led him to adopt an authoritarian stance toward his social inferiors.

Never backing away from scientific controversy, Hare waded into meteorology with an argument that tornadoes were the product of electrical currents in the atmosphere. Most famously, however, in 1854, he took on the task of testing Michael Faraday's theory that Spiritualist table-tilting was the product of involuntary muscular actions. Ever an ingenious mechanic, Hare developed an apparatus he called the Spiritoscope, designed to detect mediumistic fraud, and in the process of testing his machine, he became a Spiritualist convert. His undeniable scientific credentials made him a particularly fortunate believer for the movement, and with the publication of his book, Experimental Investigation of the Spirit Manifestations... (1855), Hare became one of the best known Spiritualists in the nation. Concomitantly, he drew the full wrath of the movement's adversaries. After a public lecture defending Spiritualist investigation before the American Association for the Advancement of Science, he drew calls for his expulsion from the organization, which appear only to have caused Hare to become more retrenchant in his views. However, never an orthodox religionist, his apparent agnosticism or atheism proved as unpalatable to Spiritualists as it did to non-Spiritualists. Nevertheless, he went to his grave with a firm belief that his device could “facilitate intercourse between spirits and mortals.”

Hare was a member of the American Academy of Arts and Sciences, the American Association for the Advancement of Science, and the American Philosophical Society. He was also an honorary member of the Smithsonian Institution. He died unexpectedly in Philadelphia in May, 1858, leaving behind his wife, Harriet Clark, and six children.
