Richard Pockrich, Poekrich (c.1695 – 1759), or Puckeridge, was an Irish musician, and was the inventor of the glass harp (also known as the "Angelic organ") in 1741.
He was born at his family's estate Derrylusk at Aghnamallagh, County Monaghan, Ireland. His father, also named Richard (c.1666–1719), was the member of Parliament for Monaghan and had commanded troops in the Williamite battles. The paternal descent was of an English family from Surrey. Some notices indicate that Poekrich was the name of the family, and this was the spelling he gave on his works. He is reported to have been aged 25 when his father died (1720?), so a probable year of birth has been fixed to 1695. Poekrich received a substantial inheritance, valued at a figure between £1,000 (Newburgh) and £4,000 (Pilkington).
Variations of his name include Puckeridge or Pokeridge, or styled as 'Captain Poekrich' in contemporary notices. His unsuccessful ventures included a brewery in Dublin, near Islandbridge, the tale of its decline is intertwined with that of his greatest success, his musical glasses. When bailiffs came to arrest Poekrich for his debts, he entranced them with an impromptu performance on his 'angelick organ'; his subsequent pardon is given as the earliest example of a belief in the psychological effect of the instrument, later adopted by Mesmer.
Another proposal was raising geese on barren terrain of his purchases in County Wicklow. Other schemes included an observatory to pursue his interest in astrology. His imagination extended to an orchestra of various sized drums, arranged to be played by one person.
His political involvement included lobbying the Parliament of Ireland for planting vineyards by draining the Irish bogs. He also proposed the development of metal hulled ships, some 100 years before their eventual introduction, carrying lifeboats made of tin. Despite his grand platform for election, he failed to win when he ran for Parliament (twice, 1745 Monaghan and 1749 Dublin).
