Abstract
This article includes information on the proposal approved in the plenary session of the Madrid City Council held on January 28, 2020, to honor the work of the scientist Andrés Manuel del Río (1764-1849), born in Madrid, through several initiatives. His work has been widely highlighted during the celebration of the International Year of the Periodic Table (2019), especially in Spain and Mexico (his host country), for being the discoverer of erythronium (current vanadium). In addition, other related aspects are briefly mentioned, such as relationships between science and municipal policies, and del Río’s biography.
