Antonio Pacinotti (1841 to 1912) was an Italian physicist and professor of physics at the University of Pisa who is best known for inventing an improved direct current dynamo. Born and died in Pisa, he was the son of Luigi Pacinotti, studied under Carlo Matteucci, graduated in mathematics under Riccardo Felici and took part in the second Italian war of independence as a volunteer sergeant. He became assistant to the astronomer Giovanni Battista Donati in 1862, professor at the technological institute of Bologna in 1864, professor at Cagliari in 1873 and in 1881 succeeded his father in the chair of technological physics at Pisa, where Augusto Righi was among his students. In 1860 he built a dynamo with a ring armature wrapped with a coil of wire, which gave a smoother current than earlier types, and he described it in a paper in Il Nuovo Cimento in 1865. He found that the device could also work as an electric motor. In 1862 he was one of several independent discoverers of the comet 109P/Swift-Tuttle.
