Bonpland became friendly with Jussieu and Lamarck after graduating from university. He met Humboldt by chance, staying at the same hotel in Paris; they travelled together for five years undertaking wide-ranging and often pioneering scientific research in Central and South America, and visited Jefferson in Washington. Humboldt credited Bonpland in all 23 volumes of his published research, rather than just the two that he collaborated on. Bonpland translated a Spanish work for Cuvier (who later thanked him for the continuing supply of South American specimens), and met Banks.
