IN: The Beatles were an English rock band, formed in Liverpool in 1960. With members John Lennon, Paul McCartney, George Harrison and Ringo Starr, they became widely regarded as the foremost and most influential act of the rock era. In the early 1960s, their enormous popularity first emerged as "Beatlemania", but as the group's music grew in sophistication, led by primary songwriters Lennon and McCartney, the band were integral to pop music's evolution into an art form and to the development of the counterculture of the 1960s. Their continued commercial and critical success assisted many cultural movements--including a shift from American artists' global dominance of rock and roll to British acts (British Invasion), the proliferation of young musicians in the 1960s who formed new bands, the album as the dominant form of record consumption over singles, the term "Beatlesque" used to describe similar-sounding artists, and several fashion trends.

The Beatles' impact on the US was particularly strong, where a garage rock phenomenon had already begun, with hits such as "Louie Louie" by the Kingsmen. The movement received a major lift following the group's historic appearance on The Ed Sullivan Show watched by a record-breaking viewing audience of a nation mourning the recent death of President John F. Kennedy. Bill Dean writes: "It's impossible to say just how many of America's young people began playing guitars and forming bands in the wake of The Beatles' appearance on the Sullivan show. But the anecdotal evidence suggests thousands - if not hundreds of thousands or even more - young musicians across the country formed bands and proceeded to play." Tom Petty, who played in two garage bands in Gainesville, Florida during the 1960s, is quoted mentioning the Beatles' appearance on The Ed Sullivan Show and how it influenced him to be in a band. According to him: "Within weeks of that, you could drive through literally any neighborhood in Gainesville and you would hear the strains of garage bands playing ... I mean everywhere. And I'd say by a year from that time, Gainesville probably had 50 bands." For many, particularly young baby boomers, the Beatles' visit reignited the sense of excitement and possibility that had been momentarily taken by Kennedy's assassination. Much of this new excitement would be expressed in music, sometimes much to the chagrin of parents and elders, as kids raced to start bands by thousands, and this proliferation of new groups was not limited to the United States. While the Beatles are often credited for sparking a musical revolution, research conducted by the Queen Mary University of London and Imperial College London suggests that the changes sparked by the band were already developing long before they entered the US. The study, which looks at shifts in chord progressions, beats, lyrics and vocals, shows that American music in the beginning of the 1960s was already moving away from mellow sounds like doo-wop and into more energetic rock styles. Professor Armand Lero argues that the Beatles' innovations have been overstated by music historians: "They didn't make a revolution or spark a revolution, they joined one. The trend is already emerging and they rode that wave, which accounts for their incredible success." Beatles biographer Mark Lewisohn disagreed with the research by Queen Mary University, saying it "[doesn't] stack up ... Speak to anyone who was a young person in the US when The Beatles arrived and they will tell you how much of a revolution it was. They were there and they will tell you that the Beatles revolutionised everything."

input: Lewis "Lew" Wallace was born on April 10, 1827, in Brookville, Indiana. He was the second of four sons born to Esther French Wallace (nee Test) and David Wallace. Lew's father, a graduate of the U.S. Military Academy in West Point, New York, left the military in 1822 and moved to Brookville, where he established a law practice and entered Indiana politics. David served in the Indiana General Assembly and later as the state's lieutenant governor, and governor, and as a member of Congress. Lew Wallace's maternal grandfather was circuit court judge and Congressman John Test. In 1832 the family moved to Covington, Indiana, where Lew's mother died from tuberculosis on July 14, 1834. In December 1836, David married nineteen-year-old Zerelda Gray Sanders Wallace, who later became a prominent suffragist and temperance advocate. In 1837, after David's election as governor of Indiana, the family moved to Indianapolis. Lew began his formal education at the age of six at a public school in Covington, but he much preferred the outdoors. Wallace had a talent for drawing and loved to read, but he was a discipline problem at school. In 1836, at the age of nine, Lew joined his older brother in Crawfordsville, Indiana, where he briefly attended the preparatory school division of Wabash College, but soon transferred to another school more suitable for his age. In 1840, when Wallace was thirteen, his father sent him to a private academy at Centerville, Indiana, where his teacher encouraged Lew's natural affinity for writing. Wallace returned to Indianapolis the following year. Sixteen-year-old Lew went out to earn his own wages in 1842, after his father refused to pay for more schooling. Wallace found a job copying records at the Marion County clerk's office and lived in an Indianapolis boardinghouse. He also joined the Marion Rifles, a local militia unit, and began writing his first novel, The Fair God, but it was not published until 1873. Wallace said in his autobiography that he had never been a member of any organized religion, but he did believe "in the Christian conception of God". By 1846, at the start of the Mexican-American War, the nineteen-year-old Wallace was studying law at his father's law office, but left that pursuit to establish a recruiting office for the Marion Volunteers in Indianapolis. He was appointed a second lieutenant, and on June 19, 1846, mustered into military service with the Marion Volunteers (also known as Company H, 1st Indiana Volunteer Infantry). Wallace rose to the position of regimental adjutant and the rank of first lieutenant while serving in the army of Zachary Taylor, but Wallace personally did not participate in combat. Wallace was mustered out of the volunteer service on June 15, 1847, and returned to Indiana, where he intended to practice law. After the war, Wallace and William B. Greer operated a Free Soil newspaper, The Free Soil Banner, in Indianapolis.
