The hospital, which was originally intended only for Protestant patients, was founded by Dr. Albert Jasper Walsh when he was just 26 years old, in 1839. It was named after Adelaide, wife of William IV. The well-known physicians John T. Kirby and Maurice Colles were honorary surgeons. Its first premises was at 43 Bride Street and it continued there until 1846. It was then closed for a time and, after new funding was secured, re-opened in Peter Street in 1858, close to two existing schools of medicine. One of these, the Ledwich School, was incorporated into the hospital in 1894. The founder of the Sunbeam House, Lucinda Sullivan, served as the first lady superintendent of the hospital from 1872 to 1875. The Adelaide hospital was a general teaching hospital for many years and in the forefront of medical advances. Its charter, which was one of the last royal charters granted in Ireland, dates from 1920. When the Irish Hospitals' Sweepstake was set up in 1930 to finance hospitals, the Adelaide was the only hospital at the time not to accept money from the Hospitals Trust, as the governors disapproved of sweepstakes. It was absorbed into the Tallaght Hospital in June 1998. The former hospital building in Peter Street has been converted into apartments and office suites known as Adelaide Chambers.
