The Secret of Success

Since 1989, Dave Thomas, who died at age 69, was one of the most recognizable faces on TV. He appeared more than 800 commercials for the hamburger chain named for his daughter. "As long as it works," he said in 1991 ,"I’11 continue to do those commercials. "

Even though he was successful, Thomas remained troubled by his childhood. "He still won’t let anyone see his feet, which are out of shape because he has never had proper-fitting shoes," Wendy said in 1993 and told us that sixty-one years ago, Dave Thomas was born to a single mother, he was adopted as a baby by Rex and Auleva. Thomas of Kalamazoo in Michigan when he was six weeks old. After Auleva died when he was 5,Thomas spent years on the road as Rex traveled around seeking construction work. " He fed me," Thomas said, "and if I got out of line, he’d beat me. " "When I found out I was (adopted), I didn’t want to talk about it, and as I talked to people I grew older... I got really a lot of encouragement. " When he was 12 years old, Thomas started working at a barbecue restaurant in Knoxville, Tenne. Moving out on his own at 15, Thomas worked, first as a waiter, in many restaurant. But he had something much better in mind. "I thought if I owned a restaurant," he said, "I could eat for free. " When he was 24, meeting with Harland Sanders led Thomas to a career as a manager of a Kentucky Fried Chicken restaurant that made him a millionaire in 1968.

A year later, after breaking with Sanders, Thomas started the first Wendy’s Old Fashioned Hamburgers, in Columbus, Ohio, which set itself apart by serving made-to-order burgers. With 6,000 restaurants worldwide, the chain now makes $ 6 billion a year in sales.

Although troubled by his own experience with an adoption, Thomas, married since 1954 to Lorraine, 66, and with four grown kids besides Wendy, felt it could offer a future for other children. He started the Dave Thomas Foundation for adoption in 1992. Later, Thomas, who had left school at 15, graduated from Coconut Great High School in Florida. He even took Lorraine to the graduation dance party. The kids voted him "Most likely to succeed" Thomas is survived by his wife of 47 years, Lorraine, five children and 16 grandchildren. His foundation helps raise awareness for the 134000 foster children available for adoption, and helps make adoption more affordable. "The Dave you saw on TV was the real Dave," said his friend Pat Williams. "He wasn’t a great actor or a great speaker. " He was just Joe Everybody.
