The correspondence between the physicist Laura Bassi (1711-1778) from Bologna and the physician and scientist Giovanni Bianchi (1693-1775) from Rimini comprehends altogether 17 letters from 1733 to 1745. Concerning Bassi, these letters are one of the few sources from a period which was decisive for her personal and scientific development; as to Bianchi, they confirm in many details the traditional picture of his person. The estimation, in which Bassi was held by Bianchi, her scientific training and her marriage are important subjects of the correspondence. Furthermore, Bianchi often sent her copies of his publications.
