Charles Haliday influenced Joyce.  James Joyce left Dublin in 1904, so much of his writing was done in Italy, Switzerland and France.  He needed meticulous detail on Dublin for his writings, including Finnegans Wake, The Dead, and others.  Some of this was provided by the writings of Charles Haliday (1789-1866)(left), medical practitioner, philanthropist, writer, and medical campaigner who lived in Monkstown.  His house is within the grounds of the Christian Brothers College, Monkstown, and his grave is in Carrickbrennan Graveyard.  His writings include The Scandinavian Kingdom of Dublin.  Haliday died on the weekend of the dedication of St Patrick's RC church, and his funeral service at Monkstown Church of Ireland was held the next day.
