The celebrated actor Junius Brutus Booth immigrated to the United States from England in the early 1820s and settled his family in Harford County, Maryland, where the ninth of his 10 children, John Wilkes, was born on May 10, 1838. In 1846, it was revealed that Junius Booth had neglected to divorce his first wife before eloping with his second, Mary Ann, 25 years before. The scandal made an impression on young John Wilkes, who was fiercely proud of his illustrious family name.

After his father's death in 1852, Booth left his studies at the prestigious military school St. Timothy's Hall. In 1855, he followed his older brothers, Junius Jr. and Edwin, into the acting profession, making his debut in Shakespeare's Richard III at the Charles Street Theatre in Baltimore. Booth worked for a year at a Philadelphia theater before moving to the Marshall Theatre in Richmond, Virginia, where he became known for his dark good looks, his intensely physical, almost acrobatic, performances and his popularity with women.

In October 1859, Booth--who, like many Marylanders, supported slavery--was shocked and galvanized by the abolitionist John Brown's bloody raid on Harper's Ferry, Virginia. Booth briefly enlisted in the Richmond militia and witnessed Brown's hanging in December. That summer, he signed on as the leading man in a touring theater company. Booth was about to take on the part of Hamlet in October 1860 when he accidentally shot himself in the thigh with a co-star's pistol. Abraham Lincoln was elected president one month later, and Booth watched the South move toward secession while recuperating in Philadelphia.

Shortly after the outbreak of the Civil War, Lincoln declared martial law in Maryland as part of an effort to keep the state from seceding. Angry and frustrated, Booth nonetheless promised his mother he would never enlist in the Confederate Army. He continued his acting career, drawing crowds and impressing critics from St. Louis to Boston. In November 1863, he performed in The Marble Heart at Washington's Ford's Theatre. In the audience were President and Mrs. Lincoln. It was the only time Lincoln would see Booth perform.

In late May 1864, Booth invested in an oil company in western Pennsylvania. After seeing no immediate profit, he backed out of the operation, losing most of his savings. By that time, he had already begun working on his conspiracy to kidnap Lincoln. He performed less and less frequently, and by late 1864 had gone into debt. Booth attended Lincoln's second inaugural in early March with his secret fiancée Lucy Hale, the daughter of an abolitionist New Hampshire senator. In what would be his last performance, Booth appeared in front of a full house at Ford's in The Apostate on March 28, 1865.

Less than a week later, Confederate forces evacuated Richmond, and within two weeks, General Robert E. Leesurrendered his troops. As Washington exploded in celebration, Booth attended another Lincoln speech on April 11, reacting strongly to Lincoln's suggestion that he would pursue voting rights for blacks. Booth angrily told his co-conspirator, Davy Herold: "Now, by God, I'll put him through." Three days later, at Ford's Theatre, John Wilkes Booth made good on his word.
