Scientific career

Angeli studied in Padua, where he met the chemist Giacomo Luigi Ciamician. When Ciamician moved to a new appointment in Bologna, he chose Angeli to work as his assistant, even before Angeli had graduated. In 1891, Angeli was awarded his doctorate in chemistry at Bologna. In 1893, he became a lecturer in Bologna, and in 1895 he became a professor. In 1894, he worked briefly in Munich with

, learning medicinal chemistry. In 1897, he moved to the University of Palermo where he became Professor of Pharmaceutical Chemistry. In 1913, Angeli became director of the Pharmacy School in Florence. In 1915, he became Professor of Organic Chemistry at the University of Florence (Istituto di Studi Superiori), a position that was created specifically for him. Angeli focused on nitrogen compounds. He investigated the structure of hydrazoic acid, synthesised nitrohydroxylamine (1894), and discovered the
