FACTBOX: Rock and Roll Hall of Fame inductees

NEW YORK (Reuters) - Pop star Madonna, folk singer Leonard Cohen, rocker John Mellencamp, pop group The Dave Clark Five and instrumental band The Ventures will be inducted into the Rock and Roll Hall of Fame on Monday.

Here is a brief biography of each inductee:

MADONNA Ciccone made her debut in 1982 and her first album "Madonna" included hits such as "Holiday," "Borderline" and "Lucky Star," which helped her become one of the best-selling pop artists, with more than 200 million albums sold worldwide.

The 49-year-old -- known for constantly reinventing her image -- will release her 11th studio album, "Hard Candy," next month. Forbes.com has dubbed her the "Cash Queen of Music," saying she earned $72 million in the past year.

The Grammy winner also has written children's books, acted in movies including "Evita," "Desperately Seeking Susan" and "Dick Tracy," and recently directed her first feature film, "Filth and Wisdom."

She is married to British director Guy Ritchie, with whom she has a son, Rocco. The couple also are raising a young Malawian boy, David, whom they are adopting. She has a daughter, Lourdes, from a previous relationship.

LEONARD COHEN is a gravel-voiced Canadian whose songs tell of love and sex, faith and betrayal. He published four books of poetry and two novels before trying music, partly to escape from life as a starving artist.

His 1967 debut album, "Songs of Leonard Cohen," included what became one of his most popular songs, "Suzanne." Other favorites include "Hallelujah," "Sisters of Mercy" and "Bird on a Wire." His songs have been recorded by R.E.M., Billy Joel, Elton John, Don Henley and others.

Born in Montreal, Cohen started his musical career in New York in the late 1960s. He fought depression and retreated to a California monastery in the 1990s to study Zen.
