How did Alexander von Humboldt help young scientists such as Justus von Liebig and Louis Agassiz?

Alexander von Humboldt was widely recognized for his magnanimity and commitment to supporting young scientists at the beginning of their careers. Driven by his generosity and wise judgment, he provided promising students who lacked funds with the necessary encouragement, financial assistance, and vital introductions to the scientific community to ensure their success.1

His support was instrumental for several notable figures:

• Justus von Liebig: Humboldt’s patronage and influence were key factors in the German chemist's appointment to the University of Giessen in 1824, which allowed Liebig to focus his energies on his groundbreaking research.2
• Louis Agassiz: While Agassiz was living as an impecunious student in Paris, Humboldt provided him with kindly interest and support, which included securing a professorship for him at Neuchâtel.3

Humboldt’s dedication to fostering new talent was a hallmark of his professional life, reflecting his vision of the collaborative and supportive nature of scientific advancement.1
