The Swiss-Russian economist Nikolay Ivanovich Sieber (1844–1888) has been unduly forgotten for his role in the history of early Russian Marxism, as well as in his role in the history of the Ukrainian revolutionary movement. Besides these injustices, that are too big to restore in this chapter, another aspect of Sieber is put forward: Sieber’s work has a contemporary appeal in offering an alternative renewal of classical political economy. The forthcoming translation into English of Sieber’s David Ricardo’s Theory of Value and Capital (1871) is intended to give an impetus to this new view on Sieber.
