Jefferson Lines (JL) is a regional intercity bus company operating in United States. The company's name originates in the Jefferson Highway, a north-south route in the early National Auto Trail system which once ran from Winnipeg in Manitoba, Canada, south to New Orleans, Louisiana. The service to Winnipeg was cut back to Grand Forks, North Dakota on October 7, 2010. Today, the Jefferson Lines system extends from Grand Forks south to Dallas, Texas. The company is operated by Jefferson Partners L.P., based in Minneapolis, Minnesota. Jefferson Partners also operates the Jefferson Tours charter bus service for tours and other group services.

Founded in 1919 during the early days of motorcoach travel, the company serves 13 states as of 2011:

In 1990, the company was believed to be the second-largest intercity bus company in the country. Intercity bus lines underwent many changes in the 2000s decade after Greyhound Lines declined into bankruptcy and subsequently shed off many bus routes. Jefferson Lines has taken over operation of many former Greyhound routes and has been able to improve ridership significantly on some of them. The company is now believed to be the country's largest intercity bus system outside of the busy East Coast market.

George Jefferson is a fictional character played by Sherman Hemsley on the American television sitcoms All in the Family (from 1973 until 1975) and its spin-off The Jeffersons (1975–1985). The character appears in all 253 episodes of The Jeffersons.

George Jefferson was born in Harlem in 1929, an ambitious African-American entrepreneur who started and managed a successful chain of seven dry cleaning stores in New York City. The only background on the Jefferson family is that they were Alabama sharecroppers. In a very early episode, George's wife Louise makes mention of a conversation she had with George's father after she and George were married about the Jeffersons family roots. However, the show's writers later applied a retroactive change in the continuity of George's father, such that he had died when George was 10 years old. This left George to take care of his mother; therefore, George was unable to complete high school. He was a cook in the US Navy during the Korean War. He began dating Louise when they were teenagers and married her upon his discharge from the navy.

Grace Slick (born Grace Barnett Wing; October 30, 1939) is an American singer, songwriter, and former model, best known as one of the lead singers of the rock groups The Great Society, Jefferson Airplane, Jefferson Starship, and Starship, as well as for her work as a solo artist from the mid-1960s to the mid-1990s. Slick was an important figure in the 1960s psychedelic rock movement, known for her witty lyrics and powerful contralto vocals.

Grace Barnett Wing was born in Evanston, Illinois, to Ivan W. Wing (1907–1987) and Virginia (née Barnett; 1910–1984), the latter a direct descendant of passengers of the Mayflower). In 1949, a month before her tenth birthday, her brother Chris Wing was born. Her father was transferred several times when she was a child and, in addition to the Chicago area, she lived in Los Angeles and San Francisco before her family finally settled in Palo Alto, California, south of San Francisco, in the early 1950s. She attended Palo Alto Senior High School before switching to Castilleja High School, a private all-girls school in Palo Alto. Following graduation she attended Finch College in New York from 1957 to 1958 and the University of Miami in Coral Gables, Florida, from 1958–1959.

Thomas Jefferson (April 13, 1743 (April 2, 1743 O.S.) – July 4, 1826) was an American Founding Father, the principal author of the United States Declaration of Independence (1776) and the third President of the United States (1801–1809). At the beginning of the American Revolution, Jefferson served in the Continental Congress, representing Virginia. He then served as a wartime Governor of Virginia (1779–1781). Just after the war ended, from mid-1784 Jefferson served as a diplomat, stationed in Paris, initially as a commissioner to help negotiate commercial treaties. In May 1785, he became the United States Minister to France. He was the first United States Secretary of State (1790–1793) during the administration of President George Washington. Upon resigning his office, with his close friend James Madison he organized the Democratic-Republican Party. Elected Vice-President in 1796, under his opponent John Adams, Jefferson with Madison secretly wrote the Kentucky and Virginia Resolutions, which attempted to nullify the Alien and Sedition Acts.

Friedrich Wilhelm Heinrich Alexander Freiherr von Humboldt ( listen (help·info) September 14, 1769 – May 6, 1859) was a German geographer, naturalist and explorer, and the younger brother of the Prussian minister, philosopher and linguist Wilhelm von Humboldt (1767–1835). Humboldt's quantitative work on botanical geography laid the foundation for the field of biogeography.

Between 1799 and 1804, Humboldt travelled extensively in Latin America, exploring and describing it for the first time in a manner generally considered to be a modern scientific point of view. His description of the journey was written up and published in an enormous set of volumes over 21 years. He was one of the first to propose that the lands bordering the Atlantic Ocean were once joined (South America and Africa in particular). Later, his five-volume work, Kosmos (1845), attempted to unify the various branches of scientific knowledge. Humboldt supported and worked with other scientists, including Joseph-Louis Gay-Lussac, Justus von Liebig, Louis Agassiz, Matthew Fontaine Maury and, most notably, Aimé Bonpland, with whom he conducted much of his scientific exploration.
