Charles Haliday (1789–1866) was an Irish public health reformer, historian and antiquary who made significant contributions to the study of the history of Dublin, being particularly interested in the Scandinavian antiquities of the city.
[2] In 1832, when cholera first appeared in Dublin, he became a campaigner for improved living conditions among the city's poor, a role he was to play for the remainder of his life.
During the construction of the railway along the coast of Dublin, Haliday ensured that access was maintained to a bathing area at Dun Laoghaire.
[2] He was elected a Member of the Ballast Board in 1833, a corporation for improving Dublin harbour and superintending the lighthouses on the Irish coast.
He also served for many years as consul for Greece, honorary secretary of the Chamber of Commerce in Dublin, and a director of the Bank of Ireland.
It was this work which led him to undertake a detailed study of the city's Scandinavian history, a period that had hitherto been almost entirely neglected by scholars.
