Joseph Pedott, a native Chicagoan and the advertising mastermind behind the iconic ‘80s products the Clapper and the Chia Pet, died recently at 91.

Services were held Tuesday for Pedott in San Francisco, where he relocated in 1958 after graduating with a bachelor’s degree in journalism in 1955 from the University of Illinois at Urbana-Champaign and running his advertising business in Chicago.

He began the advertising agency, Pedott & Peters, with his friend Daryl Peters while going to school at the U. of I., according to a 2018 blog post on the university’s website.

The partners would work at their company in Chicago all weekend, and then drive back to campus at 5 a.m. Monday morning. The hard work paid off as the company grew, and after his last course, Pedott moved to Chicago to manage the business full time.

In 1980 while attending a housewares trade show in search of new clients, Pedott learned about a terra cotta planter shaped like a ram that grew chia sprouts resembling hair when watered, according to a timeline of the product’s history on chia.com. The inventor said it was popular but not profitable so Pedott bought the rights and investigated further.

Pedott created a new company, Joseph Enterprises, Inc., to make the Chias, according to the Smithsonian, which featured the Chia and another famous product of the 1980s, the Clapper, in an exhibit about American icons.

Two years after that fateful meeting at the trade show, the Chia ram debuted, followed by more animals over the years including turtles, kittens and puppies and then later pop culture figures from Homer Simpson to The Child aka Baby Yoda from “The Mandalorian.” There is even a Chia Obama.

As for that famous phrase “Ch-Ch-Ch-Chia,” the company’s website says it either was created during an agency brainstorming session or night out at the bar. Either way, someone stuttered the word Chia and a jingle was born, according to chia.com. 

The catchy jingles continued with The Clapper, a gadget that turned lights on and off when someone clapped or as the catchphrase goes “clap on, clap off.” That product was released in 1985.

His companies Joseph Enterprises and Joseph Pedott Advertising and Marketing were acquired in 2018 by National Entertainment Collectibles Association, according to a news release at the time.

Pedott has said his success has been a wonderful surprise.

“It’s hard for me even to accept,” he said, according to the U. of I. blog post. “It’s just amazing — an achievement beyond my wildest dreams.”

Even though he lived in California for many years, Pedott was still committed to his hometown, supporting organizations like the Chicago Community Trust.
