Lampronti, Isaac, a Jewish Rabbi of some note as an author, flourished in Ferrara in the first half of the 18th century. He died about 1756. He commenced the preparation of a large encyclopaedia of Rabbinism, of which he himself completed twelve volumes, bringing the work, excellent in its character, down to the letter Mem. It was published at Venice between 1750 and 1813. See Jost, Gesch. d. Judenth. u. s. Sekten, 3:230.
