American Academy of Arts and SciencesThe American Academy of Arts and Sciences (AAA&S) is one of the oldest learned societies in the United States. It was founded in 1780 during the American Revolution by John Adams, John Hancock, James Bowdoin, Andrew Oliver, and other Founding Fathers of the United States. It is headquartered in Cambridge, Massachusetts. Membership in the academy is achieved through a thorough petition, review, and election process. The academy's quarterly journal, Dædalus, is published by the MIT Press on behalf of the academy.
Planter classThe planter class, known alternatively in the United States as the Southern aristocracy, was a racial and socioeconomic caste of pan-American society that dominated 17th and 18th century agricultural markets. The Atlantic slave trade permitted planters access to inexpensive African slave labor for the planting and harvesting of crops such as tobacco, cotton, indigo, coffee, tea, cocoa, sugarcane, sisal, oil seeds, oil palms, hemp, rubber trees, and fruits. Planters were considered part of the American gentry.

VariolationVariolation was the method of inoculation first used to immunize individuals against smallpox (Variola) with material taken from a patient or a recently variolated individual, in the hope that a mild, but protective, infection would result. Only 1–2% of those variolated died from the intentional infection compared to 30% who contracted smallpox naturally. Variolation is no longer used today. It was replaced by the smallpox vaccine, a safer alternative. This in turn led to the development of the many vaccines now available against other diseases.
