William Thomas 'Tommy' Dunn of Germantown, co-founder of the Pic-Pac and Giant Foods grocery chains, died of complications following surgery Monday, July 1, at St. Francis hospital. He was 84. Mr. Dunn and his brother, Maurice D. Dunn of Memphis, built Pic-Pac into one of the most well known grocery chains in Memphis. The first small Pic-Pac opened on Jackson in 1947. Tommy Dunn started in the grocery business at age 11 as a shelf and carry out boy in Clarence Saunder's Piggly Wiggly store on Summer Avenue. In 1961 Mr. Dunn told the Commercial Appeal "I got an occasional nod or grin from Mr. Saunders in those days. A few years later, after I'd studied commercial drawing at the old Tech High School on Lauderdale I was put to work on advertising layouts and got to know Mr. Saunders better." Mr. Dunn came up with the name Pic-Pac as a teenager and his nephew, Karl Dunn of Memphis "He was working for a meat market and talked the owner into changing the name to Pic-Pac. The guy said Pic-Pac would never work" Karl said. Tommy Dunn proved him wrong. In 1961 Pic-Pac bought five big Weingarten Food Centers in a $1 million deal. After retiring from the grocery business, Tommy Dunn had a partnership in Dunn Realty. He was a World War II veteran and a member of Germantown Methodist Church.
