CORAOPOLIS, PA — It was the summer of 1968, and Ed Stack, 13 years old at the time, hated working for his dad, Richard Stack, the founder of Dick’s Sporting Goods. Back then, the business was just a single bait and tackle shop in Binghamton, New York. And during that miserable summer, as he explains in his new book, Ed couldn’t have predicted that he would go on to scale his father’s business, much against his father’s will, to a chain of more than 700 stores. Ed would go on to take over the company from his dad in 1984, when he was then 29 years old. He would take the company public in 2002. And — again something Ed and his father both couldn’t have ever predicted — Ed would spark a national debate when he took a bold stance on assault-style firearms in February of 2018, following a deadly school shooting in Parkland, Florida. Shortly after that shooting, Dick’s Sporting Goods pulled high-capacity magazines from stores and halted the sale of firearms to anyone under 21 years old. Then, eight months later, as a test, the company pulled all guns from 10 stores. That went over so well, Stack said, that for roughly the past two months it’s had guns removed from another 125 stores. Now, the entire hunting category, including Dick’s Sporting Goods’ Field & Stream business, is under “strategic review.”
