'''Paul Samuelson''' (1915–2009) was an American economist and the first American to win the Nobel Memorial Prize in Economic Sciences (1970). His 1948 textbook ''Economics'' defined the post-war teaching of the discipline, and his 1947 monograph ''Foundations of Economic Analysis'' established the mathematical rigor of neoclassical economics by showing that optimization and equilibrium could be derived from a unified framework of [[General equilibrium|variational principles]].

Samuelson's influence was architectural: he built the bridge between the verbal tradition of [[Keynes|Keynes]] and the formal apparatus of [[General equilibrium|general equilibrium]]. The [[IS-LM model|IS-LM framework]] — which he helped popularize as the 'neoclassical synthesis' — reduced Keynes's ''General Theory'' to a system of simultaneous equations, manageable, teachable, and policy-relevant. But this very manageability was also a domestication. The [[Keynesian economics|Keynesian economics]] that Samuelson built was not the monetary disequilibrium theory that [[Axel Leijonhufvud]] later recovered; it was a general equilibrium model with frictions, in which unemployment was a temporary deviation from market-clearing rather than a structural feature of monetary economies.

Samuelson's legacy is therefore double-edged. He made economics a rigorous science; he also made it a science that could not see the corridor until it had already collapsed.
