Thomas Andrew "Colonel Tom" Parker was a Dutch-born American talent manager, best known as the manager of Elvis Presley. His management of Presley defined the role of masterminding talent management, which involved every facet of the client's life and was seen as central to the success of Presley's career. Parker's healthy compensation has led some to question whether it came at the detriment of his client. While other managers took compensation in the range of 10–15 percent of earnings, Parker took as much as 50 percent toward the end of Presley's life. Presley said of Parker, "I don't think I'd have ever been very big if it wasn't for him. He's a very smart man." For many years, Parker falsely claimed to have been born in the United States, but it eventually emerged that he had been born in the Netherlands.
