Bruce Frederick Joseph Springsteen (born September 23, 1949), nicknamed "The Boss," is an American singer-songwriter-performer who records and tours with the E Street Band. Springsteen is widely known for his brand of heartland rock, poetic lyrics, and Americana sentiments centered on his native New Jersey.

Springsteen's recordings have included both commercially accessible rock albums and more somber folk-oriented works. His most successful studio albums, Born in the U.S.A. and Born to Run, showcase a talent for finding grandeur in the struggles of daily American life; he has sold more than 65 million albums in the United States and more than 120 million worldwide and he has earned numerous awards for his work, including 21 Grammy Awards, two Golden Globes and an Academy Award. He is widely regarded by many as one of the most influential songwriters of the 20th century, and in 2004, Rolling Stone ranked him as the 23rd Greatest Artist of all time.

Springsteen was born in Long Branch, New Jersey, and spent his childhood and high school years in Freehold Borough. He lived on South Street in Freehold Borough and attended Freehold Borough High School. His father, Douglas Frederick Springsteen, was of Dutch and Irish ancestry and worked, among other vocations, as a bus driver, although he was frequently unemployed; his surname is Dutch for jump stone.
