Moritz Daniel Oppenheim was a German painter who is often regarded as the first Jewish painter of the modern era. His work was informed by his cultural and religious roots at a time when many of his German Jewish contemporaries chose to convert to Christianity. Oppenheim is considered by the scholar Ismar Schorsch to be in sympathy with the ideals of the Wissenschaft des Judentums movement, because he remained "fair to the present" without denying his past.
John Newton Mitchell was the 67th Attorney General of the United States under President Richard Nixon and a convicted criminal. Prior to that, he had been a municipal bond lawyer, chairman of Nixon's 1968 presidential campaign, and one of Nixon's closest personal friends.
After his tenure as U.S. Attorney General, he served as chairman of Nixon's 1972 presidential campaign. Due to multiple crimes he committed in the Watergate affair, Mitchell was sentenced to prison in 1977 and served 19 months. As Attorney General, he was noted for personifying the "law-and-order" positions of the Nixon Administration, amid several high-profile anti-war demonstrations.
The American frontier includes the geography, history, folklore, and cultural expression of life in the forward wave of American expansion that began with English colonial settlements in the early 17th century and ended with the admission of the last remaining western territories as states in 1912. This era of massive migration and settlement was particularly encouraged by President Thomas Jefferson following the Louisiana Purchase, giving rise to the expansionist philosophy known as "Manifest Destiny".
A frontier is a zone of contact at the edge of a line of settlement. Leading theorist Frederick Jackson Turner went deeper, arguing that the frontier was the defining process of American civilization: "The frontier," he asserted, "promoted the formation of a composite nationality for the American people." He theorized it was a process of development: "This perennial rebirth, this fluidity of American life, this expansion westward...furnish[es] the forces dominating American character."
