The First Part gives the information required by all visitors, and indicates which of Dublin's many interesting features are of most importance, should a selection have to be made.
The Second Part, the "Dictionary" proper, appeals to residents, to visitors making a long stay, and to those with but little time who want to glran information on special points. It gives, in alphabetical order, a concise, but full, description of everything worthy of mention in the City, and of features of interest within easy reach."
- from The Dictionary of Dublin, Preface

Ephraim McDowel Cosgrave (1853 - 1925), was born in Dublin on July 17th, 1853. He was a member of the Royal College of Physcians of Ireland and served as president from 1914-15.

Outside of his profession as a physician, Cosgrave was deeply interested in the history of Dublin. He was one of the principal founders of the Georgian Society and served as the Society's Honorary Secretary. 

Cosgrave became a member of the Royal Society of Antiquaries of Ireland in 1894, Fellow in 1908, and was a Member of the Council. His collection of lantern slides of Dublin was presented to the Society upon his passing.
