We pay tribute to one of the greatest pioneers of economics, Paul Samuelson, who has died at the age of ninety-four. He was the second person ever to win a Nobel Prize for economics. He is best known for bringing together different branches of the discipline to make a logical whole. Millions of economics students have read his work, which has been translated into forty or more languages.

He was a contemporary of John Maynard Keynes and believed governments had to spend money in hard times to restore full employment. In late November 2009, he gave an interview to Business Daily. He told presenter Lesley Curwen about his vivid memories of the Great Depression, and his belief that more deficit spending is needed today to improve America's economy.
