Entre a batuta e o tubo de ensaio: a carreira admirável de Alexandre Borodin

Alexander Borodin (1833-1887) is a singularity in the history of science. Whereas other scientists may have kept lifelong interests in some artistic field, he was unique in pursuing with great success two parallel careers in both chemistry and music, managing to excell in both to the end of his life. Although he considered himself primarily a chemist, present-day appreciation of his powerful music has greatly surpassed interest for his chemistry. This article treats the life and the unusual double career of the Russian chemist-musician.

O químico e naturalista luso-brasileiro Alexandre Antonio Vandelli

Alexandre Vandelli was the heir of two illustrious scientific traditions in the Luso-Brazilian world of the late eighteenth and early nineteenth centuries, that of his father, the celebrated Italian-Portuguese naturalist and chemist Domingos (Domenico) Vandelli, and that of his father-in-law, that protean figure in several scientific specialties as well as in politics, José Bonifácio de Andrada e Silva, who in later life was of paramount importance in the process of Brazilian independence from Portugal. The younger Vandelli followed their footsteps but soon engaged in a multiple career, at first in Portugal and later in Brazil, of which little is known and is here presented for the first time.
