Marilyn Chambers, the blue eyed blond haried women who symbolized purity while selling laundry detergent that later went on to become one of the first mainstream porn superstars, died Sunday in her Los Angeles home. She was 56.

She was found by her 17-year-old daughter, McKenna Marie Taylor.

Chambers briefly worked as a legitimate model, most notably as the mother on an Ivory Snow box holding a baby under the tag line “99 & 44/100% pure.”

She later had a bit part in the 1970 Barbra Streisand flick “The Owl and the Pussycat,” before breaking into the adult film world with a role in 1972’s “Behind the Green Door” – the first porn film released widely in the U.S.
