Marco Coltellini (1719 – 1777) was an Italian opera tenor, librettist and printer. Coltellini embarked on a career in the Church, but had to leave after fathering four daughters. He set up a printing shop in Livorno to publish the works of Enlightenment figures such as Francesco Algarotti and Cesare Beccaria. Wikipedia
