HONOLULU (AP) — Wallace “Wally” Amos, the creator of the cookie empire that took his name and made it famous and who went on to become a children’s literacy advocate, has died. He was 88.

Amos created the Famous Amos cookie empire and eventually lost ownership of the company — as well as the rights to use the catchy Amos name. In his later years, he became a proprietor of a cookie shop called Chip & Cookie in Hawaii, where he moved in 1977.

He died Tuesday at his home in Honolulu, with his wife, Carol, at his side, his children said. He died from complications with dementia, they said.

“With his Panama hat, kazoo, and boundless optimism, Famous Amos was a great American success story, and a source of Black pride,” said a statement from his children, Sarah, Michael, Gregory and Shawn Amos.

They said their dad “inspired a generation of entrepreneurs when he founded the world’s first cookie store” on Sunset Boulevard in Los Angeles in 1975.

Wally Amos was also co-founder of Uncle Wally’s Muffin Co., whose products are found in stores nationwide. But Amos said the fame never really mattered much to him.

“Being famous is highly overrated anyway,” Amos told The Associated Press in 2007.

His muffin company, based in Shirley, N.Y., was originally founded as Uncle Noname Cookie Co. in 1992, a few years after Amos lost Famous Amos, which still widely uses his name on its products.

Amos had said the Famous Amos cookies sold today are unlike his cookies, which had lots of chocolate, real butter and pure vanilla extract.

“You can’t compare a machine-made cookie with handmade cookie,” he told the AP. “It’s like comparing a Rolls Royce with a Volkswagen.”

Uncle Noname, however, foundered because of debt and problems with its contracted manufacturers.

The company filed for bankruptcy in 1996, abandoned cookies and went into muffins at the suggestion of Amos’ business partner, Lou Avignone.

Inside his now-shuttered Hawaii cookie shop, he sold bite-sized cookies similar to the ones he first sold at the Famous Amos Hollywood store.

Amos also was active in promoting reading. His shop, for example, had a reading room with dozens of donated books, and Amos usually spent Saturdays sitting on a rocking chair, wearing a watermelon hat, reading to children.

The former high school dropout penned eight books, served as spokesperson for Literacy Volunteers of America for 24 years and gave motivational talks to corporations, universities and other groups.

Amos earned numerous honors for his volunteerism, including the Literacy Award presented by President George H.W. Bush in 1991.

“Your greatest contribution to your country is not your signature straw hat in the Smithsonian, but the people you have inspired to learn to read,” Bush said.

In one of his books, “Man With No Name: Turn Lemons Into Lemonade,” Amos explained how he lost Famous Amos even before it was sold for $63 million to a Taiwanese company in 1991. Despite robust sales, by 1985, the business was losing money, so Amos brought in outside investors.

“The new owners gobbled up more of my share until all of a sudden, I found I had lost all ownership in the company I founded,” Amos wrote. Before long, the company had changed ownership four times.

Born in Tallahassee, Florida, Amos moved to New York City at age 12 because of his parents’ divorce. He lived with an aunt, Della Bryant, who taught him how to make chocolate chip cookies.

He later dropped out of high school to join the Air Force before working as a mailroom clerk at the William Morris Agency, where he became a talent agent, working with The Supremes, Simon & Garfunkel and Marvin Gaye before borrowing $25,000 to launch his cookie business.

He was the first Black agent in the business, his son, Shawn Amos, said.

“Our dad taught us the value of hard work, believing in ourselves, and chasing our dreams,” his children’s statement said. “We also know he would love it if you had a chocolate chip cookie today.”
