The modern history of the study of oscillating chemical reactions in the liquid phase began in Russia in 1951, when B. P. Belousov discovered temporal oscillations in the ratio [Ce(IV)]/[Ce(III)] during the cerium-ion-catalyzed oxidation of citric acid in acidic bromate.

However, Belousov was not able to get his discovery published until 1958. The first English translation of Belousov´s original manuscript appeared in Oscillations and Traveling Waves in Chemical Systems  a book edited by Richard J. Field and Mária Burger (Wiley, 1985, ISBN 0-471-89384-6).
