Researching John Eaton

Eaton was a lawyer in Tennessee who became part of a network that supported the political campaigns of Andrew Jackson. He also served in the militia as a major, and during the War of 1812 became an aide to Jackson; Eaton served with Jackson in all his wartime campaigns and battles, including the Battle of New Orleans. After serving in the Tennessee House of Representatives in 1815 and 1816, in 1818 Eaton was elected to the United States Senate, though he had not yet reached the constitutionally mandated age of 30.

Following Jackson's election to the presidency in 1828, Eaton resigned his Senate seat to join Jackson's cabinet as Secretary of War. Eaton and his wife Peggy became the focus of controversy during Jackson's first term; in the so-called Petticoat affair, Washington's society wives refused to socialize with the Eatons. The wives of the vice president, cabinet members, and members of Congress looked down on Peggy because of the circumstances of her marriage to Eaton; they had wed shortly after the death of her first husband, without waiting for the usual mourning period, giving rise to rumors that she had been unfaithful to her first husband before his death. Eaton resigned as Secretary of War as part of a strategy to resolve the controversy; he later received appointments as Governor of Florida Territory and U.S. Minister to Spain.

Upon returning to the United States in 1840, Eaton refused to endorse incumbent Martin Van Buren for reelection to the presidency, angering Jackson. In retirement, Eaton resided in Washington. He died there in 1856, and was buried at Oak Hill Cemetery.

John David's grandfather was Timothy Eaton, founder of the now-defunct T. Eaton Company department stores (better known as Eaton's). John David's father, Sir John, took on the role of president of the company when the founder died in 1907.

Born in Bryn Mawr, Pennsylvania, Eaton attended Princeton University, where he graduated in 1957. He later lived in Rome (1957–68), returning to Princeton to earn a PhD in 1970. He subsequently held faculty appointments at Indiana University (1970–92) and the University of Chicago (1989–99).

Eaton was a prominent composer of microtonal music, and worked with Paul Ketoff and Robert Moog during the 1960s in developing several types of synthesizer. Notably, he was involved in the development, use, and ultimately unsuccessful commercialization of the SynKet. He devised a compositional genre called pocket opera, operas scored for a small cast of vocalists and a chamber group, and composed such pocket opera works as Peer Gynt, Let's Get This Show on the Road, and The Curious Case of Benjamin Button.

His operas include The Cry of Clytaemnestra (1980), a re-telling of some of the events surrounding the Trojan War from the perspective of Agamemnon's wife Clytaemnestra, which has been hailed as the first feminist opera. It was premièred in Bloomington, at the Indiana University Opera Theater, on March 1, 1980, and received a number of subsequent productions, most notably in New York and California. Eaton's opera, The Tempest, with a libretto by Andrew Porter after William Shakespeare, was premièred at the Santa Fe Opera on July 27, 1985, and subsequently performed in the autumn of 1986 at the Indiana University School of Music.

During his tenure at the University of Chicago, Eaton concentrated on works for smaller ensembles, including chamber operas that involved dramatic participation of the instrumentalists alongside the singers. He founded and directed The Pocket Opera Players, a professional troupe dedicated to the performance of his works in this genre, and occasionally those of fellow composers interested in the form. He continued to lead the Pocket Opera Players in New York City, after his retirement from Chicago in 2001. He was a recipient of the Prix de Rome, a Guggenheim Fellowship, and a MacArthur Fellowship.

Eaton died on December 2, 2015, following a brain hemorrhage. His wife Nelda Nelson-Eaton and two children, Estela and Julian, survive him.

Characterized by Nat Hentoff as "the complete pianist... the master of just about the whole spectrum of jazz music", John Eaton is profiled in Leonard Feather and Ira Gitler's Encyclopedia of Jazz, and has been reviewed by prominent music critics.

Eaton is known for a CD series project "John Eaton Presents the American Popular Song" in cooperation with the Wolf Trap Foundation for the Performing Arts, the operational partner of the Wolf Trap National Park for the Performing Arts, comprising thirteen separate, recorded broadcast programs in concert and conversation with jazz bassist Jay Leonhart. Each program focuses on major artists, composers or collaborators in American music, including Richard Rodgers, Harold Arlen, George Gershwin, Jerome Kern, Cole Porter, Julie Styne, Irving Berlin, Kurt Weill and Vernon Duke, and Hoagy Carmichael and Fats Waller, Duke Ellington, Harry Warren, Jimmy Van Heusen, Frank Loesser, The Beatles, and Bob Dylan.
