The 18th-century Anglo-Irish statesman Edmund Burke, who opposed the French Revolution but supported the American Revolution, is credited as one of the forefathers of conservative thought in the 1790s along with Savoyard statesman Joseph de Maistre. The first established use of the term in a political context originated in 1818 with François-René de Chateaubriand during the period of Bourbon Restoration that sought to roll back the policies of the French Revolution and establish social order.
José Paranhos, Viscount of Rio Branco (1819–1880) was a politician, monarchist, diplomat, teacher and journalist of the Empire of Brazil. Rio Branco's work in the press, highlighting threats posed by the armed conflicts in the Platine republics (Argentina and Uruguay), attracted the attention of Honório Hermeto Carneiro Leão, Marquis of Paraná, who invited him to act as secretary on a diplomatic mission to Montevideo. In 1869, he dispatched to Paraguay, this time to negotiate an end to its war with Brazil. In 1871, Rio Branco became the president of the Council of Ministers for the first time. He would become the Council's longest-serving president, and his cabinet the second longest, in Brazilian history. His government was marked by a time of economic prosperity and the enactment of several necessary reforms. The most important of these initiatives was the Rio Branco Law, which granted freeborn status to children born to slave women. Rio Branco died in 1880 and was widely mourned throughout the country. He is regarded by most historians as one of Brazil's greatest statesmen.
This outrage on all the rights of property was at first covered with what, on the system of their conduct, was the most astonishing of all pretexts-a regard to national faith. The enemies to property at first pretended a most tender, delicate, and scrupulous anxiety for keeping the king's engagements with the public creditor. These professors of the right of men are to busy in teaching others, that they not leisure to learn any thing themselves; otherwise they would have known that it is to the property of the citizen, and not to the demands of the creditor of the state, that the first and original faith of civil society is pledged. The claim of the citizen is prior in time, paramount in title, superior in equity. The fortunes of individuals, whether possessed by acquisition, or by descent, or in virtue of participation in the goods of some community, were no part of the creditor's security, expressed, or implied. They never so much as entered into his head when he made his bargain. He well knew that the public, whether represented by a monarch, or by a senate, can pledge nothing but the public estate; and it can have no public estate, expect in what it derives from a just and proportioned imposition upon the citizens at large. This was engaged, and nothing else could be engaged to the public creditor. No man can mortgage his injustice as a pawn for his fidelity.
—Edmund Burke, Reflections on the Revolution in France (1790)
Teller emigrated to the United States in the 1930s, and was an early member of the Manhattan Project charged with developing the first atomic bombs. During this time he made a serious push to develop the first fusion-based weapons as well, but these were deferred until after World War II. In his later years he became especially known for his advocacy of controversial technological solutions to both military and civilian problems, including a plan to excavate an artificial harbor in Alaska using thermonuclear explosives. He was a vigorous advocate of Ronald Reagan's Strategic Defense Initiative. Over the course of his life, Teller was known both for his scientific ability and his difficult interpersonal relations and volatile personality, and is considered one of the inspirations for the character Dr. Strangelove in the 1964 movie of the same name.
