The "father" of Starbucks' Pumpkin Spice Latte says "it was the flavor that almost wasn't"

Peter Dukes is credited with being the man behind the coffee confection that came to define a whole season: Starbucks' Pumpkin Spice Latte. It all began in the company's Seattle headquarters in 2001.

"You are the father of PSL?" CBS News' Michelle Miller asked, referring to the beverage.

"That's what some say. Yes," said Dukes.
