Paul A. Samuelson, whose analytical work laid the foundation for modern economics, died Sunday. He was 94. Actively publishing into the 2000s, Mr. Samuelson’s career in economics spanned eight decades. In 1970, he was the first American to win the Nobel Prize in economics, the second year the prize was offered.
To anybody who has spent time studying economics, this is s huge loss. I still have a copy of his econ text from college (and that was over 20 years ago). It is still a great source of basic information. Here is a link to his works on Amazon.
