Robert Sean Wilentz ( /ˈʃɔːn wɨˈlɛnts/) is the Sidney and Ruth Lapidus Professor of History at Princeton University, where he has taught since 1979.

Born in 1951 in New York City, where his father Eli and uncle Ted owned a well-known Greenwich Village bookstore, the Eighth Street Bookshop, Wilentz earned one B.A. at Columbia University in 1972, before earning another at Oxford University (Balliol College) in 1974 on a Kellett Fellowship. In 1975 he earned an M.A. at Yale University and in 1980 he received his Ph.D. also from Yale, under the supervision of David Brion Davis.

Wilentz' historical scholarship has focused on the importance of class and race in the early national period, especially in New York City. Wilentz has also co-authored books on nineteenth-century religion and working-class life. His highly detailed The Rise of American Democracy: Jefferson to Lincoln (W.W. Norton, 2005) won the Bancroft Prize. His goal was to revive the reputation of Andrew Jackson and Jacksonian Democracy, which was under attack from the left because of Jackson's support for slavery and especially his harshness toward Indians, including his forced removals. Wilentz returned to the pro-Jackson themes of Arthur Schlesinger Jr., who in 1946 had hailed the pro-labor policies of Northern, urban Jacksonians.

Bob Dylan ( /ˈdɪlən/), born Robert Allen Zimmerman on May 24, 1941, is an American singer-songwriter, musician and artist. He has been an influential figure in popular music and culture for five decades. Much of his most celebrated work dates from the 1960s when he was an informal chronicler and a seemingly reluctant figurehead of social unrest. A number of Dylan's early songs, such as "Blowin' in the Wind" and "The Times They Are a-Changin'", became anthems for the US civil rights and anti-war movements. Leaving his initial base in the culture of folk music behind, Dylan's six-minute single "Like a Rolling Stone" has been described as radically altering the parameters of popular music in 1965. However, his recordings employing electric instruments attracted denunciation and criticism from others in the folk movement.

Dylan's lyrics incorporated a variety of political, social, philosophical, and literary influences. They defied existing pop music conventions and appealed hugely to the then burgeoning counterculture. Initially inspired by the songs of Woody Guthrie,Robert Johnson, and Hank Williams, as well as the music and performance styles of Buddy Holly and Little Richard, Dylan has both amplified and personalized musical genres. His recording career, spanning fifty years, has explored numerous distinct traditions in American song—from folk, blues and country to gospel, rock and roll, and rockabilly to English, Scottish, and Irish folk music, embracing even jazz and swing.

Charles Peete "Charlie" Rose, Jr. (born January 5, 1942) is an American television talk show host and journalist. Since 1991 he has hosted Charlie Rose, an interview show distributed nationally by PBS since 1993. He has also co-anchored CBS This Morning since January 2012. Rose, along with Lara Logan, has hosted the revived CBS classic Person to Person, a news program during which celebrities are interviewed in their homes, originally hosted from 1953 to 1961 by Edward R. Murrow.

Rose was born in Henderson, North Carolina, the only child of Margaret Frazier and Charles Peete Rose, Sr., tobacco farmers who owned a country store. As a child, Rose lived above his parents' store in Henderson and helped out with the family business from age seven. Rose admitted in a Fresh Dialogues interview that as a child his insatiable curiosity was constantly getting him in trouble. A high school basketball star, Rose entered Duke University intending to pursue a degree with a pre-med track, but an internship in the office of Democratic North Carolina Senator B. Everett Jordan got him interested in politics. Rose graduated in 1964 with a bachelor's degree in history. At Duke, he was a member of the Kappa Alpha Order fraternity. He earned a Juris Doctor from the Duke University School of Law in 1968. He met his wife, Mary (née King), while attending Duke.

Barack Hussein Obama II (ⁱ/bəˈrɑːk huːˈseɪn oʊˈbɑːmə/; born August 4, 1961) is the 44th and current President of the United States. He is the first African American to hold the office. In January 2005, Obama was sworn in as a U.S. Senator in the state of Illinois. He would hold this office until November 2008, when he resigned following his victory in the 2008 presidential election.

Born in Honolulu, Hawaii, Obama is a graduate of Columbia University and Harvard Law School, where he was the president of the Harvard Law Review. He was a community organizer in Chicago before earning his law degree. He worked as a civil rights attorney in Chicago and taught constitutional law at the University of Chicago Law School from 1992 to 2004. He served three terms representing the 13th District in the Illinois Senate from 1997 to 2004.

Following an unsuccessful bid against the Democratic incumbent for a seat in the United States House of Representatives in 2000, Obama ran for the United States Senate in 2004. Several events brought him to national attention during the campaign, including his victory in the March 2004 Illinois Democratic primary for the Senate election and his keynote address at the Democratic National Convention in July 2004. He won election to the U.S. Senate in Illinois in November 2004. His presidential campaign began in February 2007, and after a close campaign in the 2008 Democratic Party presidential primaries against Hillary Rodham Clinton, he won his party's nomination. In the 2008 presidential election, he defeated Republican nominee John McCain, and was inaugurated as president on January 20, 2009. Nine months later, Obama was named the 2009 Nobel Peace Prize laureate. In April 2011, he announced that he would be running for re-election in 2012.
