Biography
Andrés Manuel del Río was a man of two worlds, a Spanish-born scientist whose greatest contributions unfolded in the burgeoning nation of Mexico. Educated in Spain and France, he brought his expertise in mineralogy to the New World, becoming a professor at the Royal School of Mines in Mexico City. In 1801, while analyzing a rare brown lead ore from Zimapán, he isolated a new metallic element with striking, colorful compounds. He named it 'erythronium' for its red salts. When he sent samples to European colleagues, a shipwreck and a mistaken analysis led the scientific establishment to dismiss his find. It wasn't until 1830 that the Swedish chemist Nils Sefström rediscovered the element, naming it vanadium. Del Río lived long enough to see his priority finally acknowledged, his career a story of prescient discovery shadowed by colonial scientific politics.

Key Achievements
- First isolated and identified the element vanadium (which he named erythronium) from Mexican lead ore in 1801.
- Served as a founding professor and director of the Royal School of Mines in Mexico City.
- Published seminal works on the mineralogy of Mexico, including 'Elementos de Orictognosia'.
- His pioneering work was later validated, and he is now recognized as the original discoverer of vanadium.
Did You Know?
The mineral delrioite is named in his honor.
He was a member of the Basque Society of Friends of the Country, a key Enlightenment group.
He initially proposed the name 'panchromium' for vanadium due to its wide range of colorful salts.
He survived political upheavals in both Spain and Mexico, maintaining his scientific work throughout.
“This red-brown mineral from Zimapán contains a new metallic element, which I call erythronium.”
