The old room of veterinary dissections and the School of veterinary science were both founded in 1845. Pietro Delprato, Professor of veterinary Medicine, was the first director of the School. He entrusted the anatomist Alessio Lemoigne with anatomic preparations having prevailing didactic aim. The collection was housed in the rooms of San Vitale Garden and in 1857 it numbered 191 preparations of various mammals. In the same year, Professor Alessio Lemoigne was named as the new director of the old room Museum of veterinary dissections.
Professor Lemoigne enlarged the collection with unique specimens and trained students who imitated his ability to dissect animals (one of his students, Professor Clemente Papi, after having moved to Bologna, founded the veterinary anatomical Museum of the University of Bologna in 1882)
