Highlights for January 27
1302 Dante is exiled from Florence
On this day, poet and politician Dante Alighieri is exiled from Florence, where he served as one of six priors governing the city. Dante's political activities, including the banishing of several rivals, led to his own banishment, and he wrote his masterpiece, The Divine Comedy, as a virtual wanderer, seeking protection for his family in town after town.
Dante was born to a family with noble ancestry that had fallen in fortunes. He began writing poetry in his teens and received encouragement from established poets, to whom he sent sonnets as a young man.
At age nine, Dante first caught a glimpse of Beatrice Portinari, also nine, who would symbolize for him perfect female beauty and spiritual goodness in the coming decades. Despite his fervent devotion to Portinari, who did not seem to return his feelings, Dante became engaged to Gemma Donati in 1277, but the two did not marry until eight years later. The couple had six sons and a daughter.
About 1293, Dante published a book of prose and poetry called The New Life, followed a few years later by another collection, The Banquet. It wasn't until his banishment that he began work on his Divine Comedy. In the poem's first book, the poet takes a tour through Hell with the poet Virgil as a guide. Virgil also guides the poet through Purgatory in the second book. The poet's guide in Paradise, however, is named Beatrice. The work was written and published in sections between 1308 and 1321. Although Dante called the work simply Comedy, the work became enormously popular, and a deluxe version published in 1555 in Venice bore the title The Divine Comedy. Dante died of malaria in Ravenna in 1321.
1926: Baird Demonstrated Mechanical Television
On January 27, 1926, John Logie Baird, a Scottish inventor, gives the first public demonstration of a true television system in London, launching a revolution in communication and entertainment. Baird's invention, a pictorial-transmission machine he called a "televisor," used mechanical rotating disks to scan moving images into electronic impulses. This information was then transmitted by cable to a screen where it showed up as a low-resolution pattern of light and dark. Baird's first television program showed the heads of two ventriloquist dummies, which he operated in front of the camera apparatus out of view of the audience.
Baird based his television on the work of Paul Nipkow, a German scientist who patented his ideas for a complete television system in 1884. Nipkow likewise used a rotating disk with holes in it to scan images, but he never achieved more than the crudest of shadowy pictures. Various inventors worked to develop this idea, and Baird was the first to achieve easily discernible images. In 1928, Baird made the first overseas broadcast from London to New York over phone lines and in the same year demonstrated the first color television.
The first home television receiver was demonstrated in Schenectady, New York, in January 1928, and by May a station began occasional broadcasts to the handful of homes in the area that were given the General Electric-built machines. In 1932, the Radio Corporation of America demonstrated an all-electronic television using a cathode-ray tube in the receiver and the "iconoscope" camera tube developed by Russian-born physicist Vladimir Zworykin. These two inventions greatly improved picture quality.
The British Broadcasting Corporation (BBC) inaugurated regular high-definition public broadcasts in London in 1936. In delivering the broadcasts, Baird's television system was in competition with one promoted by Marconi Electric and Musical Industries. Marconi's television, which produced a 405-line picture--compared with Baird's 240 lines--was clearly better, and in early 1937 the BBC adopted the Marconi system exclusively. Regular television broadcasts began in the United States in 1939, and permanent color broadcasts began in 1954.
1951 First atomic detonation at the Nevada test site
Forcefully marking the continued importance of the West in the development of nuclear weaponry, the government detonates the first of a series of nuclear bombs at its new Nevada test site.
Although much of the West had long lagged behind the rest of the nation in technological and industrial development, the massive World War II project to build the first atomic bomb single-handedly pushed the region into the 20th century. Code named the Manhattan Project, this ambitious research and development program pumped millions of dollars of federal funds into new western research centers like the bomb building lab at Los Alamos, New Mexico and the fissionable material production center at Hanford, Washington. Ironically, the very conditions that had once impeded western technological development became benefits: lots of wide-open unpopulated federal land where dangerous experiments could be conducted in secret.
After the war ended, the West continued to be the ideal region for Cold War-era nuclear experimentation for the same reasons. In December 1950, the Atomic Energy Commission designated a large swath of unpopulated desert land 65 miles northwest of Las Vegas as the Nevada Proving Ground for atmospheric atomic testing. On January 27, 1951, the government detonated its first atomic device on the site, resulting in a tremendous explosion, the flash from which was seen as far away as San Francisco.
The government continued to conduct atmospheric tests for six more years at the Nevada site. They studied the effects on humans by stationing ground troops as close as 2,500 yards from ground zero and moving them even closer shortly after the detonation. By 1957, though, the effects of radioactivity on the soldiers and the surrounding population led the government to begin testing bombs underground, and by 1962, all atmospheric testing had ceased.
In recent years, the harm caused to soldiers and westerners exposed to radioactivity from the Nevada test site has become a controversial topic. Some critics argue the government waged a "nuclear war on the West," and maintain that the government knew of the dangers posed to people living near the test site well before the 1957 shift to underground tests. Others, though, point out that the test site has brought billions of dollars into the state and resulted in great economic benefit to Nevada.
1967 Astronauts die in launch pad fire
A launch pad fire during Apollo program tests at Cape Canaveral, Florida, kills astronauts Virgil "Gus" Grissom, Edward H. White II, and Roger B. Chafee. An investigation indicated that a faulty electrical wire inside the Apollo 1 command module was the probable cause of the fire. The astronauts, the first Americans to die in a spacecraft, had been participating in a simulation of the Apollo 1 launch scheduled for the next month.
The Apollo program was initiated by the National Aeronautics and Space Administration (NASA) following President John F. Kennedy's 1961 declaration of the goal of landing men on the moon and bringing them safely back to Earth by the end of the decade. The so-called "moon shot" was the largest scientific and technological undertaking in history. In December 1968, Apollo 8 was the first manned spacecraft to travel to the moon, and on July 20, 1969, astronauts Neil A. Armstrong and Edwin "Buzz" Aldrin Jr. walked on the lunar surface. In all, there were 17 Apollo missions and six lunar landings.
