When Matty Simmons first heard about multipurpose credit cards in 1950, he wasn’t impressed.
 
 At the time, Frank McNamara, who came up with the idea, and Ralph Schneider, his business partner, were trying to persuade Simmons to join their new company, Diners Club. The concept of a credit card didn’t seem especially useful to Simmons, who was doing public relations for restaurants and nightclubs at the time.
 
 “What concerned me most was that I would be asked to not only publicize this new conception but to persuade restaurants to honor it,” Simmons wrote in his 1995 book “The Credit Card Catastrophe,” a firsthand account of Diners Club’s early days and the evolution of the credit card industry.
