Johann Ernst Louis Henry Glauert (1846-1919) was born in Germany and came to England as a young man.  In 1877, Louis married in Hamburg an English wife, Amanda née Watkinson (1851-1925), who had also been born in Germany.  By then, Louis had founded L. & C. Glauert at Burgess Works in Cambridge Street.  His partner was his brother Carl (later Charles) Glauert.  They were  merchants and exporters of steel, tools, and cutlery, employing in 1881 four men and three women.  Carl died on 29 January 1891, aged 43, leaving £1,146.  Louis (who lived in Kenwood Park Road and became naturalised in 1893) became the sole partner.  The firm  was profiled in The Century’s Progress (1893).  Burgess Works moved several times – to Green Lane, then Love Street – but by 1895 the address was Wallace Works, Furnival Street.   The trade mark was a crowned eagle’s head, above the word ‘PATRIOT’, which emphasised the Glauerts’ new allegiances.  The business operated until Louis’s death on 10 March 1919, aged 72, when he left £3,835.   The family was distinguished.  Elsa Glauert (b.14 May 1892) graduated from Girton College, Cambridge.  One son, Ludwig Glauert (1879-1963), became a noted Australian naturalist and museum curator.  Another, Hermann Ludwig Glauert (1892-1934), became a Fellow of the Royal Society for his work as an aerodynamicist.  In 1934, he was walking on a common at Farnborough and paused to watch army engineers blowing up tree stumps.  A stray chunk of wood hit his forehead and killed him.
