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.

O'Brien was born in Brookline, Massachusetts, and raised in an Irish Catholic family. He served as president of the Harvard Lampoon while attending Harvard University, and was a writer for the sketch comedy series Not Necessarily the News. After writing for several comedy shows in Los Angeles, he joined the writing staff of Saturday Night Live, and later of The Simpsons. He hosted Late Night with Conan O'Brien from 1993 to 2009, followed by seven months hosting The Tonight Show with Conan O'Brien, the only person to serve as the permanent host for both NBC programs.

O'Brien was born in Brookline, Massachusetts (a suburb of Boston) to Thomas O'Brien, a physician, epidemiologist, and professor of medicine at Harvard, and Ruth O'Brien (née Reardon), an attorney and partner at the Boston firm Ropes & Gray. He is the third of six children. O'Brien's family is Irish Catholic and descends from pre-Civil War era immigrants. In a Late Night episode, O'Brien paid a visit to County Kerry, Ireland, where his ancestors originated.
