His Foundations 1947 are responsible for the envelope theorem and the full characterization of the cost function. He made important contributions to the theory of technical progress 1972 . His work on the theory of capital is well known if contentious. He demonstrated one of the first remarkable Non-Substitution theorems 1951 and in his famous paper with Solow 1953 initiated the analysis of dynamic Leontief systems. This work was reiterated in his famous 1958 volume on linear programming with Robert Dorfman and Robert Solow wherein we also find a clear introduction to the turnpike conjecture of linear von Neumann systems. Samuelson was also Joan Robinson s main adversary in the Cambridge Capital Controversy introducing the surrogate production function 1962 and then subsequently and graciously relenting 1966 .
