The partners were Joseph Beaumont (born 1837) and William Henry Beaumont (born 1835).  They were the sons of Joseph, a grocer, and his wife, Ellen.  By 1851, they were living with their widowed mother in High Street.  She was working in a warehouse; they were apprentices, possibly in the metal trades.  In 1861, Joseph and William Henry were described in the Census as Britannia metal smiths.  They still lived with their mother (now remarried) in Talbot Street.  In about 1862, the brothers launched their own Britannia metal business in Joiner Lane in the Wicker.  By 1867, when Beaumont Bros advertised in a Birmingham directory, it had begun the manufacture of electro-plate.  The workforce by 1871 was eight men, six boys, and a dozen women.   The firm remained at the same address and with the same management into the twentieth century.   Joseph Beaumont, Shoreham Street, died on 13 September 1907, aged 70, leaving £211 to his widow, Maria.  His brother continued to run the business until his death on 20 November 1923, aged 88, leaving £1,104.   William Henry’s son, Frederick Beaumont, appears to have operated Beaumont & Nicholson, electro-platers at Venture Works, Well Lane, between 1907 and 1916.   In the interwar period, J. A. & H. Beaumont operated in Rockingham Street; and Henry Beaumont, electro-plater, was listed in Joiner Lane.  Henry Beaumont was the only firm listed by 1940.
