Alexander Adie was particularly noted for his meteorological instruments and is perhaps best known as the inventor of the Sympiesometer in 1818. In recognition of his work he was elected a Fellow of the Royal Society of Edinburgh in 1819. He was appointed optician to William IV and later Queen Victoria and took one of his sons, John, into partner in 1835. Two of his other sons set up binesses; Richard in Liverpool from 1837 and Patrick in London from 1846. Unfortunately John Adie was prone to fits of despondency' which resulted in him shooting himself in 1857, Alexander Adie died the following year - no doubt expediated by the stress of his son's demise. Richard Adie subsequently spent a lot of time in Edinburgh looking after the biness of Adie and Son up until his death in 1881.The Kew pattern marine barometer was developed prior to 1855 by John Welsh of the Kew Observatory and Patrick Adie and included refinements such as iron cistern beneath thermometer bulb within the brass tube case (in order for the temperature reading to mirror that of the mercury in the tube), a restriction in the bore of the tube (to dampen the movement of the mercury) and a Bunten air trap.
