was an American inventor and businessman. He developed many devices that greatly influenced life around the world, including the phonograph, the motion picture camera, and a long-lasting, practical electric light bulb. Dubbed "The Wizard of Menlo Park", he was one of the first inventors to apply the principles of mass production and large-scale teamwork to the process of invention, and because of that, he is often credited with the creation of the first industrial research laboratory.
His advanced work in these fields was an outgrowth of his early career as a telegraph operator. Edison developed a system of electric-power generation and distribution to homes, businesses, and factories - a crucial development in the modern industrialized world. His first power station was on Pearl Street in Manhattan, New York.
The Jim Crow laws were racial segregation state and local laws enacted after the Reconstruction period in Southern United States that continued in force until 1965 mandating de jure racial segregation in all public facilities in Southern U.S. states (of the former Confederacy), starting in 1890 with a "separate but equal" status for African Americans. Conditions for African Americans were consistently inferior and underfunded compared to those provided for white Americans. This decision institutionalized a number of economic, educational and social disadvantages. De jure segregation mainly applied to the Southern United States, while Northern segregation was generally de facto — patterns of segregation in housing enforced by covenants, bank lending practices and job discrimination, including discriminatory union practices for decades.
Jim Crow laws mandated the segregation of public schools, public places and public transportation, and the segregation of restrooms, restaurants and drinking fountains for whites and blacks. The U.S. military was also segregated, as were federal workplaces, initiated in 1913 under President Woodrow Wilson, the first Southern president elected since 1856. His administration practiced overt racial discrimination in hiring, requiring candidates to submit photos.
These Jim Crow laws followed the 1800-1866 Black Codes, which had previously restricted the civil rights and civil liberties of African Americans. Segregation of public (state-sponsored) schools was declared unconstitutional by the Supreme Court of the United States in 1954 in Brown v. Board of Education. Generally, the remaining Jim Crow laws were overruled by the Civil Rights Act of 1964 and the Voting Rights Act of 1965 but years of action and court challenges were needed to unravel numerous means of institutional discrimination. Such challenges continue.
was signed on September 17 between United States treaty commissioners and representatives of the Cheyenne, Sioux, Arapaho, Crow, Assiniboine, Mandan, Hidatsa, and Arikara nations. The treaty sets forth traditional territorial claims of the tribes as among themselves. The Native Americans guaranteed safe passage for settlers on the Oregon Trail in return for promises of an annuity in the amount of fifty thousand dollars for fifty years. The Native American nations also allowed roads and forts to be built in their territories.
The United States Senate ratified the treaty, adding Article 5, to adjust compensation from fifty to ten years, if the tribes accepted the changes. Acceptance from all tribes, with the exception of the Crow, was procured. Several tribes never received the commodities promised as payments. The treaty produced a brief period of peace, but it was broken by the failure of the United States to prevent the mass emigration of settlers and miners during the Pike's Peak Gold Rush into the territories of the native nations as identified. The US government chose not to enforce the treaty to keep out the emigrants, although its economic wealth certainly allowed it to do so.
American politician most notable for being the "boss" of Tammany Hall, the Democratic Party political machine that played a major role in the politics of 19th century New York City and State. At the height of his influence, Tweed was the third-largest landowner in New York City, a director of the Erie Railroad, the Tenth National Bank, and the New-York Printing Company, as well as proprietor of the Metropolitan Hotel.
Tweed was elected to the United States House of Representatives in 1852 and the New York County Board of Supervisors in 1858, the year he became the head of the Tammany Hall political machine. He was also elected to the New York State Senate in 1867, but Tweed's greatest influence came from being an appointed member of a number of boards and commissions, his control over political patronage in New York City through Tammany, and his ability to ensure the loyalty of voters through jobs he could create and dispense on city-related projects.
as an African-American journalist, newspaper editor, suffragist, sociologist, and an early leader in the civil rights movement. She documented lynching in the United States, showing that it was often used as a way to control or punish blacks who competed with whites, rather than being based in criminal acts by blacks, as was usually claimed by white mobs. She was active in women's rights and the women's suffrage movement, establishing several notable women's organizations. Wells was a skilled and persuasive rhetorician, and traveled internationally on lecture tours
The murder of her friends drove Wells to research and document lynchings and their causes. She began investigative journalism by looking at the charges given for the murders. She also officially started her anti-lynching campaign. She spoke on the issue at various black women's clubs, and raised more than $500 to investigate lynchings and publish her results. Wells found that blacks were lynched for such reasons as failing to pay debts, not appearing to give way to whites, competing with whites economically, and being drunk in public.
