The Neoclassical Synthesist

"Mr. Samuelson wrote one of the most widely used college textbooks in the history of American education. The book, 'Economics,' first published in 1948, was the nation’s best-selling textbook for nearly 30 years. Translated into 20 languages, it was selling 50,000 copies a year a half century after it first appeared.
"'I don’t care who writes a nation’s laws—or crafts its advanced treatises—if I can write its economics textbooks,' Mr. Samuelson said."

Michael A. Weinstein in The New York Times writes an obituary for Paul A. Samuelson.
