Maurice Dixon Dunn of Memphis, co-founder of the Pic-Pac and Giant Food grocery store chains with his brother Tommy Dunn, died Monday after a prolonged bout of pneumonia. He was 91. He was born in West Union, a community near Millington. The brothers moved to Memphis when they were very young, and attended Gordon, Peabody, Treadwell, and Tech High. They learned the retail grocery business from Clarence Saunders, of Piggly Wiggly fame, while young boys. They worked in the grocery business until World War II started. Maurice then joined the Navy, and Tommy the Army. They saved their service pay to go into business for themselves. Mr. Dunn and his brother Tommy built Pic-Pac into one of the most well-known grocery chains in Memphis. The first small Pic-Pac opened on Jackson Avenue in 1947, and was only 20ft. x 40ft. Tom was the checker, and Maurice was the meat-cutter. They built their business on quality and service, and actually set a national record for "highest grocery sales per square foot". In 1953, at the grand opening of their 2nd store at Lamar and Airways, a then not so well known, Elvis Presley was featured singing to the biggest crowd that he had yet in his young career had performed to. It was at the Lamar and Airways store that they came up with the innovation of the checker calling out the prices of the merchandise, as it was being checked, instilling confidence in the customer. Pic-Pac was also the first grocery store to give Quality Stamps with food purchases. In all the Dunn brothers opened ten Pic-Pacs before an exchange of stock with Malone and Hyde, which was the largest grocery store deal in Memphis history. Maurice often recalled "that the reason they kept opening stores, was because they had to keep promoting their exceptional employees," his son, Karl said. They then went on to open the Giant Food stores which they ran for M & H until their retirement. He was a member of Christ United Methodist Church.
