Gallup Inc. was founded in 1958, when George Gallup grouped all of his polling operations into one organization. After Gallup's death in 1984, The Gallup Organization was sold to Selection Research, Incorporated (SRI) of Lincoln, Nebraska in 1988. SRI, founded in 1969 by the psychologist Don Clifton, pioneered the use of talent-based structured psychological interviews. George Gallup founded the American Institute of Public Opinion, the precursor of The Gallup Organization, in Princeton, New Jersey, in 1935. He wished to objectively determine the opinions held by the people. To ensure his independence and objectivity, Dr. Gallup resolved that he would undertake no polling that was paid for or sponsored in any way by special interest groups such as the Republican and Democratic parties, a commitment that Gallup upholds to this day.

George Horace Gallup (November 18, 1901 – July 26, 1984) was an American pioneer of survey sampling techniques and inventor of the Gallup poll, a successful statistical method of survey sampling for measuring public opinion.

Gallup was born in Jefferson, Iowa. He was a graduate of The Lawrenceville School and the University of Iowa, where he was a football player, a member of Sigma Alpha Epsilon fraternity, and editor of The Daily Iowan, an independent newspaper which serves the university campus. He earned his B.A. in 1923, his M.A. in 1925 and his Ph.D. in 1928.

In 1936, his new organization achieved national recognition by correctly predicting, from the replies of only 5,000 respondents, that Franklin Roosevelt would defeat Alf Landon in the U.S. Presidential election. This was in direct contradiction to the widely respected Literary Digest magazine whose poll based on over two million returned questionnaires predicted that Landon would be the winner. Not only did Gallup get the election right, he correctly predicted the results of the Literary Digest poll as well using a random sample smaller than theirs but chosen to match it.

Nathaniel Read "Nate" Silver (born January 13, 1978) is an American statistician, psephologist, and writer. Silver first gained public recognition for developing PECOTA, a system for forecasting the performance and career development of Major League Baseball players, which he sold to and then managed for Baseball Prospectus from 2003 to 2009.

In 2007, writing under the pseudonym "Poblano," Silver began to publish analyses and predictions related to the 2008 United States presidential election. At first this work appeared on the political blog Daily Kos, but in March 2008 Silver established his own website, FiveThirtyEight.com. By summer of that year, after he revealed his identity to his readers, he began to appear as an electoral and political analyst in national print, online, and cable news media.

The accuracy of his November 2008 presidential election predictions—he correctly predicted the winner of 49 of the 50 states—won Silver further attention and commendation. The only state he missed was Indiana, which went for Barack Obama by 0.9%. He also correctly predicted the winner of all 35 Senate races that year.
