The 1950s (pronounced nineteen-fifties; commonly abbreviated as the "Fifties" or the "'50s") (among other variants) was a decade that began on January 1, 1950, and ended on December 31, 1959.

Throughout the decade, the world continued its recovery from World War II, aided by the post-World War II economic expansion. The period also saw great population growth with increased birth rates and the emergence of the baby boomer generation. Despite this recovery, the Cold War developed from its modest beginnings in the late 1940s to a heated competition between the Soviet Union and the United States by the early 1960s. The ideological clash between communism and capitalism dominated the decade, especially in the Northern Hemisphere. (Full article...)

Color television (American English) or colour television (Commonwealth English) is a television transmission technology that includes color information for the picture, so the video image can be displayed in color on the television set. It improves on the monochrome or black-and-white television technology, which displays the image in shades of gray (grayscale). Television broadcasting stations and networks in most parts of the world upgraded from black-and-white to color transmission between the 1960s and the 1980s. The invention of color television standards was an important part of the history and technology of television.

Transmission of color images using mechanical scanners had been conceived as early as the 1880s. A demonstration of mechanically scanned color television was given by John Logie Baird in 1928, but its limitations were apparent even then. Development of electronic scanning and display made a practical system possible. Monochrome transmission standards were developed prior to World War II, but civilian electronics development was frozen during much of the war. In August 1944, Baird gave the world's first demonstration of a practical fully electronic color television display. In the United States, competing color standards were developed, finally resulting in the NTSC color standard that was compatible with the prior monochrome system. Although the NTSC color standard was proclaimed in 1953, and limited programming soon became available, it was not until the early 1970s that color television in North America outsold black-and-white units. Color broadcasting in Europe did not standardize on the PAL or SECAM formats until the 1960s. (Full article...)

Official portrait, 1959

Dwight David Eisenhower (/ˈzənh.ər/ EYE-zən-how-ər; born David Dwight Eisenhower; October 14, 1890 – March 28, 1969), nicknamed Ike, was an American military officer and statesman who served as the 34th president of the United States from 1953 to 1961. During World War II, he was Supreme Commander of the Allied Expeditionary Force in Europe and achieved the five-star rank as General of the Army. Eisenhower planned and supervised two of the most consequential military campaigns of World War II: Operation Torch in the North Africa campaign in 1942–1943 and the invasion of Normandy in 1944.

Eisenhower was born in Denison, Texas, and raised in Abilene, Kansas. His family had a strong religious background, and his mother became a Jehovah's Witness. Eisenhower, however, belonged to no organized church until 1952. He graduated from West Point in 1915 and later married Mamie Doud, with whom he had two sons. During World War I, he was denied a request to serve in Europe and instead commanded a unit that trained tank crews. Following the war, he was promoted to the rank of brigadier general. In 1941, after the United States entered World War II, Eisenhower oversaw the invasions of North Africa and Sicily before supervising the invasions of France and Germany. After the war ended in Europe, he served as military governor of the American-occupied zone of Germany (1945), Army Chief of Staff (1945–1948), president of Columbia University (1948–1953), and as the first supreme commander of NATO (1951–1952).
