František Ladislav Rieger (1818-1903), a lawyer, Viennese-Cromerian imperial deputy and later a prominent Old Bohemian politician, was one of the first Czech economists to deal with economic theory at the turn of the 1840s and 1850s. This paper aims to describe Rieger's professional qualities through an analysis of his seminal economic works and to summarize his contemporary contributions to the development of Czech economic thought.
