Robert Glenn was one of the more active piano makers of the 19th Century. Robert Glenn is listed as a partner with John Wake as early as 1839, forming the firm of “Wake & Glenn”. The partnership was short lived and was dissolved in 1842.  Robert Glenn resumed building pianos under his own name until 1844 when he partnered with Abel Rogers and formed “Glenn, Rogers & Company”.  This partnership was also short lived and ended when Robert Glenn withdrew to form his own firm “Robert, Glenn & Company” in 1846.  Robert Glenn & Company went on to build highly acclaimed pianos until his death in 1855. Pianos from any of these partnership firms are exceedingly rare and of museum caliber.
