In 1952, Thomas Watson, Sr., stepped down after almost 40 years at the company helm; his son, Thomas Watson, Jr., was named president. In 1956, the company demonstrated the first practical example of artificial intelligence when Arthur L. Samuel of IBM's Poughkeepsie, New York, laboratory programmed an IBM 704 not merely to play checkers but "learn" from its own experience. In 1957, the FORTRAN (FORmula TRANslation) scientific programming language was developed. In 1961, Thomas J. Watson, Jr., was elected chairman of the board and Albert L. Williams became company president. The same year IBM developed the SABRE (Semi-Automatic Business-Related Environment) reservation system for American Airlines and introduced the highly successful Selectric typewriter.
What computer did Arthur L. Samuel program to play checkers in 1957?

Black labor played a crucial role in Miami's early development. During the beginning of the 20th century, migrants from the Bahamas and African-Americans constituted 40 percent of the city's population. Whatever their role in the city's growth, their community's growth was limited to a small space. When landlords began to rent homes to African-Americans in neighborhoods close to Avenue J (what would later become NW Fifth Avenue), a gang of white man with torches visited the renting families and warned them to move or be bombed.
Where did a portion of Miami's black population migrate from in the early 1900s?
Bahamas

The city was incorporated in 1854, the same year in which the Camden and Atlantic Railroad train service began. Built on the edge of the bay, this served as the direct link of this remote parcel of land with Philadelphia, Pennsylvania. That same year, construction of the Absecon Lighthouse, designed by George Meade of the Corps of Topographical Engineers, was approved, with work initiated the next year. By 1874, almost 500,000 passengers a year were coming to Atlantic City by rail. In Boardwalk Empire: The Birth, High Times, and Corruption of Atlantic City, "Atlantic City's Godfather" Nelson Johnson describes the inspiration of Dr. Jonathan Pitney (the "Father of Atlantic City") to develop Atlantic City as a health resort, his efforts to convince the municipal authorities that a railroad to the beach would be beneficial, his successful alliance with Samuel Richards (entrepreneur and member of the most influential family in southern New Jersey at the time) to achieve that goal, the actual building of the railroad, and the experience of the first 600 riders, who "were chosen carefully by Samuel Richards and Jonathan Pitney":
What other US city was linked to Atlantic City by the Camden and Atlantic Railroad train service?
