Paul Samuelson, 1915-2009

Samuelson Michael Weinstein in the NYT:

When economists “sit down with a piece of paper to calculate or analyze something, you would have to say that no one was more important in providing the tools they use and the ideas that they employ than Paul Samuelson,” said Robert M. Solow, a fellow Nobel laureate and colleague.of Mr. Samuelson’s at M.I.T.

Mr. Samuelson attracted a brilliant roster of economists to teach or study at the Cambridge, Mass., university, among them Mr. Solow as well as such other future Nobel laureates as George A. Akerlof, Robert F. Engle III, Lawrence R. Klein, Paul Krugman, Franco Modigliani, Robert C. Merton and Joseph E. Stiglitz.

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.

His textbook taught college students how to think about economics. His technical work — especially his discipline-shattering Ph.D. thesis, immodestly titled “The Foundations of Economic Analysis” — taught professional economists how to ply their trade. Between the two books, Mr. Samuelson redefined modern economics.
