All in all, 1962 was a pretty sweet year.

Jacqueline Kennedy gave the first TV tour of the White House; Jackie Robinson was elected to the Baseball Hall of Fame; the Beatles released their first single,  “West Side Story” won the Best Picture Oscar.

And Joe von Elbe, a new food science professor at the University of Wisconsin-Madison, drove down to Herb Knechtel’s research and development laboratory in Skokie, Illinois, to pick up equipment for the first Resident Course in Confectionery Technology—or, as it’s known to the hundreds of students who have taken the course over the past half century, “the candy school.”

Hosted by the UW-Madison College of Agricultural and Life Sciences and the National Confectioners Association, the course has become an important training ground for the candy industry. Professor Rich Hartel coordinates the program now, but von Elbe continues to help teach it. Hundreds of students — from line workers and company owners to technical staff and suppliers — have learned the science of candy from the world’s confectionery experts.

“The word to describe it is probably impossible,” says consultant Walt Vink, who spent 26 years with LifeSavers and attended, sent employees to and teaches in the course. Students are often competitors, he says, but when they get to campus, they share information.

As the confectionery school begins its second half-century, it is looking private support to improve students’ candy-making experience. A campaign is underway to celebrate the confectionery school’s 50th birthday and raise funds to buy new, updated equipment to ensure top results.

At its heart, candy school is about science. And the chemical and functional interactions of ingredients don’t change. Students learn the science of candies and then make them, varying ingredients to see what happens. The curriculum begins with hard candy — sugar and sugar free — includes gum, gummies and jellies, nougats and taffy, fondants and creams, panning, and ends with chocolate.

Knowing the science behind the products allows candy makers to adjust and change, says consultant Pam Gesford, who has worked for Hershey and Jelly Belly. She has taught and has sent students to the school. Understanding how ingredients act and react shows ingredient suppliers where their products will work well.

“It’s important for companies to try new products and do more with the people they already have,” Gesford says. “This kind of general course gives employees a confectionery background. I’ve seen people excel, whether they have a good science background or not much science at all.”
