Nathan Cooley Keep
Nathan Cooley Keep (1800–1875) was a pioneer in the field of dentistry, and the founding Dean of the Harvard School of Dental Medicine. Biography Keep was born in Longmeadow, Massachusetts, on December 23, 1800. Adept with his hands, he became interested in dentistry following an apprenticeship with a local jeweler. In 1821, he moved to Boston and graduated from Harvard Medical School with an M.D. in 1827. He practiced dentistry for 40 years, was hailed for his proficiency, and in 1843 was awarded an honorary D.D.S. by the Baltimore College of Dental Surgery. Keep invented and manufactured many dental tools and is credited with being one of the first to manufacture porcelain teeth. Also, a practicing physician, Keep was the first to use anesthesia for childbirth, administering ether to Fanny Longfellow, Henry Wadsworth Longfellow's wife, on the occasion of her daughter's birth on April 7, 1847.Calhoun, Charles C.

Dentistry
Dentistry, also known as dental medicine and oral medicine, is the branch of medicine focused on the teeth, gums, and mouth. It consists of the study, diagnosis, prevention, management, and treatment of diseases, disorders, and conditions of the mouth, most commonly focused on dentition (the development and arrangement of teeth) as well as the oral mucosa. Dentistry may also encompass other aspects of the craniofacial complex including the temporomandibular joint. The practitioner is called a dentist. The history of dentistry is almost as ancient as the history of humanity and civilization with the earliest evidence dating from 7000 BC to 5500 BC. Dentistry is thought to have been the first specialization in medicine which have gone on to develop its own accredited degree with its own specializations. Dentistry is often also understood to subsume the now largely defunct medical specialty of stomatology (the study of the mouth and its disorders and diseases) for which reas ...

Henry Wadsworth Longfellow
Henry Wadsworth Longfellow (February 27, 1807 – March 24, 1882) was an American poet and educator. His original works include "Paul Revere's Ride", ''The Song of Hiawatha'', and ''Evangeline''.

Keep
A keep (from the Middle English ''kype'') is a type of fortified tower built within castles during the Middle Ages by European nobility. Scholars have debated the scope of the word ''keep'', but usually consider it to refer to large towers in castles that were fortified residences, used as a refuge of last resort should the rest of the castle fall to an adversary. The first keeps were made of timber and formed a key part of the motte-and-bailey castles that emerged in Normandy and Anjou during the 10th century; the design spread to England, south Italy and Sicily. As a result of the Norman invasion of 1066, use spread into Wales during the second half of the 11th century and into Ireland in the 1170s. The Anglo-Normans and French rulers began to build stone keeps during the 10th and 11th centuries; these included Norman keeps, with a square or rectangular design, and circular shell keeps. Stone keeps carried considerable political as well as military importance and could take up ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Robert Tanner Freeman
Robert Tanner Freeman (18461873) was an American dentist. As one of the first six students to attend the Harvard School of Dental Medicine, he became the first African American to graduate with a dental degree in the United States on March 10, 1869. He subsequently practiced dentistry in Washington, D.C. Early life and education Freeman was born near Washington, D.C., in 1846. He was the son of a carpenter who had bought his family's freedom and then moved to Raleigh, North Carolina. During his late teens, Freeman worked for a mentor, Dr. Henry Bliss Noble, a white dentist in Washington. Before Freeman was accepted into the Harvard Dental School, now the Harvard School of Dental Medicine, he was rejected by two other institutions because of the color of his skin. The dental school's first dean, Nathan Cooley Keep, interviewed him and invited him to become one of the first six students to attend Harvard Dental School. On March 10, 1869, Freeman became the first African American t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boston Brahmin
The Boston Brahmins or Boston elite are members of Boston's traditional upper class. They are often associated with Harvard University; Anglicanism; and traditional Anglo-American customs and clothing. Descendants of the earliest English colonists are typically considered to be the most representative of the Boston Brahmins. They are considered White Anglo-Saxon Protestants (WASPs). Etymology The doctor and writer Oliver Wendell Holmes, Sr. coined the term "Brahmin Caste of New England" in an 1860 story in ''The Atlantic Monthly''. The term ''Brahmin'' refers to the priestly caste within the four castes in the caste system in India, Hindu caste system. By extension, it was applied in the United States to the old wealthy New England families of British Protestant origin that became influential in the development of American institutions and culture. The influence of the old American gentry has been reduced in modern times, but some vestiges remain, primarily in the institutions ...

Chemistry
Chemistry is the science, scientific study of the properties and behavior of matter. It is a natural science that covers the Chemical element, elements that make up matter to the chemical compound, compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a Chemical reaction, reaction with other Chemical substance, substances. Chemistry also addresses the nature of chemical bonds in chemical compounds. In the scope of its subject, chemistry occupies an intermediate position between physics and biology. It is sometimes called the central science because it provides a foundation for understanding both Basic research, basic and Applied science, applied scientific disciplines at a fundamental level. For example, chemistry explains aspects of plant growth (botany), the formation of igneous rocks (geology), how atmospheric ozone is formed and how environmental pollutants are degraded (ecology), the properties ...

Parkman–Webster Murder Case
After Boston businessman George Parkman disappeared in November 1849, his dismembered and partially burned body was found in the laboratory of John Webster, a lecturer at Harvard Medical College; Webster was convicted of Parkman's murder and hanged. Highly publicized because of its gruesome nature and the high social status of Parkman and Webster, the case was one of the earliest in which forensic evidence was used to identify a body. Main participants George Parkman George Parkman (February 19, 1790 – November 23, 1849), a Boston Brahmin, belonged to one of the city's richest families. He was a well-known figure in the streets of Boston, which he walked daily, collecting his rents (a thrifty man, he did not own a horse). He was tall and lean, with a protruding chin, and wore a top hat. Oliver Wendell Holmes Sr. said that "he abstained while others indulged, he walked while others rode, he worked while others slept."

Diethyl Ether
Diethyl ether, or simply ether, is an organic compound in the ether class with the formula , sometimes abbreviated as (see Pseudoelement symbols). It is a colourless, highly volatile, sweet-smelling ("ethereal odour"), extremely flammable liquid. It is commonly used as a solvent in laboratories and as a starting fluid for some engines. It was formerly used as a general anesthetic, until non-flammable drugs were developed, such as halothane. It has been used as a recreational drug to cause intoxication. Production Most diethyl ether is produced as a byproduct of the vapor-phase hydration of ethylene to make ethanol. This process uses solid-supported phosphoric acid catalysts and can be adjusted to make more ether if the need arises. Vapor-phase dehydration of ethanol over some alumina catalysts can give diethyl ether yields of up to 95%. Diethyl ether can be prepared both in laboratories and on an industrial scale by the acid ether synthesis. Ethanol is mixed with a stro ...
