FindMyPast Ireland has added the 1858 Medical Directory for Ireland to its searchable database. It details the locations and published works of professionals holding qualifications as either apothecaries (pharmacists) or medical doctors in Ireland.
This was the year in which a Medical Act started to regulate the medical profession and to drive out unlicensed practitioners.
There's more information about this Directory and its compilation here.
The first directory of Ireland's medical profession, which was published in 1852, is also available.
These and all FindMyPast Ireland records are also available via a World Subscription with FindMyPast USA, FindMyPast Australia/NZ and FindMyPast UK.
