In the first part of the paper we describe the origin and the substance of the Post-Keynesian economics, which in the last decades became a distinctive, dissident stream of the contemporary economic thought. To its forerunners and founders belonged a group of the Cambridge economists. One of the most prominent 'proto-Post-Keynesians' was Nicholas Kaldor, whose work is appreciated in the second part of the article. There is described Kaldor's 'neoclassical' period, his transition to the Keynesian economics and his main contributions - particularly the theory of income distribution and economic growth as well as his critique of the theory of the economic equilibrium and monetarism.
