JACKSONVILLE, Ore. (AP) –  Gary Ross Dahl, the creator of the wildly popular
1970s fad the Pet Rock, has died at age 78 in southern Oregon.

Dahl’s wife, Marguerite Dahl, confirmed Tuesday that her husband of 40 years
died March 23 of chronic obstructive pulmonary disease.

The smooth stones came packed in a cardboard box containing a tongue-in-
cheek instruction pamphlet for "care and feeding." Dahl estimated he had sold
1.5 million of them at roughly $4 each by the time the fad fizzled. The Pet Rock
required no work and no time commitment.

Born Dec. 18, 1936, in Bottineau, North Dakota, Dahl was raised in Spokane, Washington.

In 1975, he was a Los Gatos, California, advertising executive when he came
up with the Pet Rock idea.
