[1] Hussey was born at Cloyne, in the county of Cork[2] and his career began as a sailor.
[2] He drew the figureheads and stern ornaments of vessels, and eventually set up in Dublin as a portrait-painter under the patronage of Lord Chancellor Bowes, painting full-length portraits with some success.
Although a notable Irish portrait painter, Hussey is not thought to be amongst the most important.
[3] His house was a meeting place of many leading men of art and letters in Dublin.
He died at an advanced age in 1783 at his house in Earl Street, Dublin.
