His body was found in Pine Lake around 3 p.m. after he had been missing all day, according to news reports.
Quad/Graphics issued a brief statement last night: "As you can imagine, this is a very sad day for the Quadracci family. Our first priority is to respect their privacy and assist them in any way we can. Mr. Quadracci will be deeply missed by everyone who knew him, including employees, the many customers with whom he had close relationships, the entire printing industry, the Wisconsin business community and the many communities where the company operates."
Police this morning continued to investigate the death. An autopsy will be conducted later today.
The Pewaukee, Wis.-based printing giant, founded in 1971, has about $2 billion in annual sales and 15 plants on three continents. The company prints catalogs for Bloomingdale's and Victoria's Secret, among others, as well as periodicals such as Advertising Age, People, Newsweek, National Geographic and Sports Illustrated.
"The entire business community has lost a friend, an innovator and a man who was universally respected," said H. Robert Wientzen, president and CEO of the Direct Marketing Association.
Mr. Quadracci, who was very involved in government affairs activities for the DMA, was a member of the DMA board of directors and executive committee.
