IN: Harry S. Truman (May 8, 1884 - December 26, 1972) was an American statesman who served as the 33rd President of the United States (1945-1953), taking the office upon the death of Franklin D. Roosevelt. A World War I veteran, he assumed the presidency during the waning months of World War II and the beginning of the Cold War. He is known for implementing the Marshall Plan to rebuild the economy of Western Europe, for the establishment of the Truman Doctrine and NATO against Soviet and Chinese Communism, and for intervening in the Korean War. In domestic affairs, he was a moderate Democrat whose liberal proposals were a continuation of Franklin Roosevelt's New Deal, but the conservative-dominated Congress blocked most of them.

Vice President Henry Wallace was popular among Democratic voters, but he was viewed as too far to the left and too friendly to labor for some of Roosevelt's advisers. The President and several of his confidantes wanted to replace Wallace with someone more acceptable to Democratic Party leaders and Roosevelt's advisors, knowing that Roosevelt might not live out a fourth term. Outgoing Democratic National Committee chairman Frank C. Walker, incoming chairman Hannegan, party treasurer Edwin W. Pauley, strategist Ed Flynn, Chicago Mayor Edward Joseph Kelly, and lobbyist George E. Allen all wanted to keep Wallace off the ticket. Roosevelt told party leaders that he would accept either Truman or Supreme Court Justice William O. Douglas. State and city party leaders strongly preferred Truman, and Roosevelt agreed. Truman did not campaign for the Vice-Presidential spot, though he welcomed the attention as evidence that he had become more than the "Senator from Pendergast".  Truman's nomination was dubbed the "Second Missouri Compromise" and was well received. The Roosevelt-Truman ticket achieved a 432-99 electoral-vote victory in the election, defeating the Republican ticket of Governor Thomas E. Dewey of New York and running mate Governor John Bricker of Ohio. Truman was sworn in as vice president on January 20, 1945.  Truman's brief vice-presidency was relatively uneventful. On April 10, 1945, Truman cast his only tie-breaking vote as President of the Senate, against a Robert A. Taft amendment that would have blocked the postwar delivery of Lend-Lease Act items contracted for during the war. Roosevelt rarely contacted him, even to inform him of major decisions; the President and Vice President met alone together only twice during their time in office. In one of his first acts as vice president, Truman created some controversy when he attended the disgraced Pendergast's funeral. He brushed aside the criticism, saying simply, "He was always my friend and I have always been his." He had rarely discussed world affairs or domestic politics with Roosevelt; he was uninformed about major initiatives relating to the war and the top-secret Manhattan Project, which was about to test the world's first atomic bomb. He was also photographed with actress Lauren Bacall sitting atop the piano at the National Press Club as he played for soldiers.  Truman had been vice president for 82 days when President Roosevelt died on April 12, 1945. That afternoon, Truman presided over the Senate as usual. He had just adjourned the session for the day and was preparing to have a drink in House Speaker Sam Rayburn's office when he received an urgent message to go immediately to the White House. Truman assumed President Roosevelt wanted to meet with him, but Eleanor Roosevelt informed him her husband had died after suffering a massive cerebral hemorrhage. Truman's first concern was for Mrs. Roosevelt. He asked if there was anything he could do for her, to which she replied, "Is there anything we can do for you? For you are the one in trouble now!"

IN: John Logie Baird FRSE (; 13 August 1888 - 14 June 1946) was a Scottish engineer, innovator, one of the inventors of the mechanical television, demonstrating the first working television system on 26 January 1926, and inventor of both the first publicly demonstrated colour television system, and the first purely electronic colour television picture tube. In 1928 the Baird Television Development Company achieved the first transatlantic television transmission. Baird's early technological successes and his role in the practical introduction of broadcast television for home entertainment have earned him a prominent place in television's history.

In 1927, Baird transmitted a long-distance television signal over 438 miles (705 km) of telephone line between London and Glasgow; Baird transmitted the world's first long-distance television pictures to the Central Hotel at Glasgow Central Station. This transmission was Baird's response to a 225-mile, long-distance telecast between stations of AT&T Bell Labs. The Bell stations were in New York and Washington, DC. The earlier telecast took place in April 1927, a month before Baird's demonstration.  Baird set up the Baird Television Development Company Ltd, which in 1928 made the first transatlantic television transmission, from London to Hartsdale, New York, and the first television programme for the BBC. In November 1929, Baird and Bernard Natan established France's first television company, Television-Baird-Natan. Broadcast on the BBC on 14 July 1930, The Man with the Flower in His Mouth was the first drama shown on UK television. Baird televised the BBC's first live outside broadcast with transmission of The Derby in 1931. He demonstrated a theatre television system, with a screen two feet by five feet (60 cm by 150 cm), in 1930 at the London Coliseum, Berlin, Paris, and Stockholm. By 1939 he had improved his theatre projection to televise a boxing match on a screen 15 ft (4.6 m) by 12 ft (3.7 m).  From 1929 to 1932, the BBC transmitters were used to broadcast television programmes using the 30-line Baird system, and from 1932 to 1935, the BBC also produced the programmes in their own studio at 16 Portland Place. On 3 November 1936, from Alexandra Palace located on the high ground of the north London ridge, the BBC began alternating Baird 240-line transmissions with EMI's electronic scanning system, which had recently been improved to 405 lines after a merger with Marconi. The Baird system at the time involved an intermediate film process, where footage was shot on cinefilm, which was rapidly developed and scanned. The trial was due to last 6 months but the BBC ceased broadcasts with the Baird system in February 1937, due in part to a disastrous fire in the Baird facilities at Crystal Palace. It was becoming apparent to the BBC that the Baird system would ultimately fail due in large part to the lack of mobility of the Baird system's cameras, with their developer tanks, hoses, and cables.  Baird's television systems were replaced by the electronic television system developed by the newly formed company EMI-Marconi under Isaac Shoenberg, which had access to patents developed by Vladimir Zworykin and RCA. Similarly, Philo T. Farnsworth's electronic "Image Dissector" camera was available to Baird's company via a patent-sharing agreement. However, the Image Dissector camera was found to be lacking in light sensitivity, requiring excessive levels of illumination. Baird used the Farnsworth tubes instead to scan cinefilm, in which capacity they proved serviceable though prone to drop-outs and other problems. Farnsworth himself came to London to Baird's Crystal Palace laboratories in 1936, but was unable to fully solve the problem; the fire that burned Crystal Palace to the ground later that year further hampered the Baird company's ability to compete.

Did he do anything else in broadcasting?
