Le 11 novembre 1999, un mode propre magnétique auto-excité était détecté pour la première fois dans l'expérience dynamo au sodium liquide de Riga. Nous relatons le long historique qui a conduit à cet événement et présentons les campagnes expérimentales qui ont suivi et qui ont produit de très nombreuses données sur les régimes cinématique et saturé de cette dynamo. L'état actuel de compréhension théorique des deux régimes est esquissée et des comparaisons avec d'autres expériences dynamo sont fournies.

On 11 November 1999, a self-exciting magnetic eigenfield was detected for the first time in the Riga liquid sodium dynamo experiment. We report on the long history leading to this event, and on the subsequent experimental campaigns which provided a wealth of data on the kinematic and the saturated regime of this dynamo. The present state of the theoretical understanding of both regimes is delineated, and some comparisons with other laboratory dynamo experiments are made.
