The banking business originated as Swift's bank at 17
Eustace Street (then number 22 Eustace Street), founded around 1722 by the merchant James Swift. In 1742 the bank moved to Castle Street and by 1745 James Swift had died and the business was taken over by the new firm of Thomas Gleadowe & Company. In 1767, Thomas was succeeded by his son
William Gleadowe. Five years later William had married an heiress,
Charlotte Gleadowe-Newcomen, 1st Viscountess Newcomen and assumed the Newcomen name. After the business collapsed in 1825, the building was later acquired by the Hibernian bank out of bankruptcy. The Hibernian bank had been founded in April 1825 as a response to anti catholic discrimination by the Bank of Ireland and had its first premises at 81
Marlborough Street before moving to the old Newcomen bank building in 1831. The Hibernian bank was itself later taken over by the
Bank of Ireland in 1958.
1820s Banking crash By 1820, there were around 28 banks in Ireland. In May 1820 Stephen and James Roche's bank in
Cork collapsed and this was followed soon after by Leslie and Company also in Cork. Over the following months and years there followed a generalised Irish banking crash and economic malaise which followed a deflationary period after the end of the Napoleonic wars. Newcomen bank as well as several other banks in the city of Dublin such as Sir William Alexander's bank also collapsed in the 1820s. The Newcomen family and several other prominent families were financially ruined leading to
Thomas Gleadowe-Newcomen, 2nd Viscount Newcomen shooting himself in his office either at the bank or at his residence at
Killester House on 15 January 1825. ==Building==
