Knut Wicksell
Johan Gustaf Knut Wicksell was a leading Swedish economist of the Stockholm school. His economic contributions would influence both the Keynesian and Austrian schools of economic thought.
Wicksell was born in Stockholm, Sweden on December 20, 1851. His father was a relatively successful businessman and real estate broker. He lost both his parents at a relatively early age his mother died when he was only six years old, and his father died when he was fifteen. His fathers considerable estate allowed him to enroll at the University of Uppsala in 1869 to study mathematics and physics. He received his first degree in two years, after which he engaged in graduate studies until 1885, when he received his doctorate in mathematics. In 1887, Wicksell received a scholarship to study on the continent where he heard lectures by the economist Carl Menger in Vienna. In the following years, his interests began to shift toward the social sciences, and in particular, economics.
