In 1844, Charles Wheatstone (1802-1875) best known for his work in the field of physics, patented the 48-button English-system concertina. The instrument had already been in production for some years following his 1829 patent for the symphonium, a free reed mouth organ. A bellows-blown model was shown in an illustration accompanying the 1829 patent. Charles Wheatstone's family had been involved in the musical instrument trade for some years, and his brother, William Dolman Wheatstone, joined the firm in 1837. He became its proprietor between 1847 and 1866, when Charles Wheatstone gave up his involvement in the company to concentrate on his scientific work, for which he was knighted and made a Fellow of the Royal Society. The following information is recorded regarding the purchase of this instrument in the ledgers of the Wheatstone & Co. concertina factory (http://www.horniman.info): 29 Mar 1854: Mr Park [£]5.5.0 [total price for four instruments] S (C1049, p.1) 20 Mar 1857: Mr B Millard 4 - - [pounds] SH (C1050, p.61) 3 Jun 1857: J Leslie Esq 5 - - [pounds] SH (C1050, p.77). Here, 'SH' stands for 'second hand', showing that the instrument had been brought back to the salesroom and was now being sold for a second time. The concertina is classified according to the system of Hornbostel and Sachs as a 'set of free reeds, with flexible air reservoir and keyboard'.
