Piano maker.  (fl. Before 1777 to 1798) in 1798 Geib emigrated from London to New York where continued to make pianos. While in London his workshop was in the vicinity of Tottenham Court Road.  Geib is best known for his 1786 patent for improvements in the pianoforte and harpsichord, particularly the square piano double action.  This action became the standard square piano action and continued to be used with slight adaptation by all makers of square pianos in the 19th century.   There are not many square pianos made by Geib with his own name. Most of his output, while in London, was made for Longman & Broderip until their bankruptcy in 1796.   Geib was in business with John Goldsworth in 1790.  The Wakefield directory of merchants and tradesman show his business as “Royal Musical Manufactory”
