Samuelson’s text was first published in 1948, and it immediately became the authority for the principles of economics courses. The book continues to be the standard-bearer for principles courses, and this revision continues to be a clear, accurate, and interesting introduction to modern economics principles. Bill Nordhaus is now the primary author of this text, and he has revised the book to be as current and relevant as ever.
Paul Anthony Samuelson (May 15, 1915 – December 13, 2009) was an American economist. The first American to win the Nobel Memorial Prize in Economic Sciences, the Swedish Royal Academies stated, when awarding the prize in 1970, that he "has done more than any other contemporary economist to raise the level of scientific analysis in economic theory". Economic historian Randall E. Parker has called him the "Father of Modern Economics", and The New York Times considered him to be the "foremost academic economist of the 20th century"
