Peter George Poulos’ booth was in the back of Margie’s Candies. Table No. 10. It’s where he’d eat, work, chat with customers and, in recent years, occasionally catch a nap.

As a baby, Mr. Poulos slept among the toffee and fudge in a crib his parents brought into the store.

Infant or aged, when his eyes opened from slumber, they saw essentially the same thing.

The shop is a near-perfect time capsule. It offers the same experience that Al Capone, Aretha Franklin and the Beatles (one of the Fab Four danced on a table) got when they walked through its doors.

Mr. Poulos, the third-generation owner of the fabled North Side confectionery and ice cream shop, died of cancer April 26 at St. Francis Hospital in Evanston. He was 86.

Mr. Poulos kept Margie’s Candies the way his mother, Margie, liked it.

As a boy, he was known as “Margie’s son” around the shop, where he’d mop the floor and clean sticky tabletops where he’d later open his school books.

Mr. Poulos’ father and grandfather opened the store in 1920 in a former bank building on Armitage and Western avenues in Bucktown and named it Security Sweet Shop.

Mr. Poulos’ parents met at the shop. Milkshakes played a role in their courtship. They wed, and the business was renamed in honor of the 18-year-old bride.

Mr. Poulos was a teenager in 1954 when his father — World War II veteran George Poulos — died of an ulcer and his mother took the reins at the shop.

She oversaw the daily production of candy and chocolate in the shop’s basement, including its most popular offering, the Terrapin.

She named the chocolate-covered caramel and pecan treat after a type of turtle because Turtle, the better-known name, was trademarked by Fannie May.

In 1995, Mr. Poulos’ mother died from a heart attack after she witnessed a car accident outside her store. 

Mr. Poulos, who’d taken his own route in life and become a podiatrist after attending the University of Chicago and Northwestern University, found himself in charge, according to family.

He moved his podiatry practice to an office across the street from Margie’s and for several years juggled operating his medical practice and running Margie’s.

After seeing patients, he’d leave his office, always in black pants, a shirt and tie, and a Mickey Mouse watch on his wrist, and head to work at Margie’s.

Mr. Poulos’ wife, Christina, who died in 2009, helped him run the store.

Not long after the couple took charge of the store, their son, George, came along, and history began to repeat itself.

“There’s pictures of me as a kid sleeping in the booths, running around the store and interacting with employees who worked there then and still work there now,” said George Poulos, 27, who grew up in Rogers Park and graduated from Loyola Academy.

Mr. Poulos died unexpectedly. Hours earlier, he’d been on the phone checking in with employees at Margie’s, making sure orders were placed, George said.

“I’m going to take over,” George said. “We plan on keeping everything the same. No changes.”

That includes maintaining Margie’s time-honored agreement with young ice cream lovers of rewarding report card A’s with a free cone. Improvement from C’s to A’s garner a banana split.

George worked weekends at Margie’s as a kid, busing tables and making fudge.

“I’d help add flavors and mix the ingredients. There’s a good amount of steps. You don’t want to mess it up. I had to get my measurements correct. It’s all done by hand. My dad was very loving. If I made a mistake, we’d start over,” he said.

“It was always nice being able to tell people we owned Margie’s, and then hear people tell their own stories about going there,” he said.

“When I was a kid I ate way too much ice cream and candy. Now I don’t eat that stuff. But my wife loves it,” he said.

Mr. Poulos loved fishing at Belmont Harbor and, in recent months, spending time with his infant grandson.

“I’m happy he got to meet his grandson,” George Poulos said of his 5-month-old. “He liked hearing him babble. I wish he could be here longer to watch him grow.”
