Halpen worked in Dublin, and was principally engaged in engraving frontispieces and vignettes for booksellers there. He executed John Rocque's Survey of Dublin in Parishes, 1757, the geometrical elevation of the parliament house, 1767, and also engraved a portrait of Dr. Charles Lucas, after Thomas Hickey. He resided in Blackamoor Yard, and was for some years the only native line-engraver in Dublin.
