The microscope was purchased from a member of the amily of the original owner who inherited it from his father, Dr. Renzo G. Olivetti (1907-1987), a physician who practiced medicine in Torino (Turin) Italy. Given the vintage of the microscope, c. 1900, it is most likely that the original owner was the grandfather, Dr. Bonaiuto Olivetti (1867-1941), who also had a medical practice in Torino. Some references by and about Dr. Bonaiuto Olivetti are available from Google books. From these references, it would seem that he specialized in gastroenterology.
