Alexander James Adie FRSE MWS (1775, Edinburgh – 4 December 1858, Edinburgh) was a Scottish maker of medical instruments, optician and meteorologist. He was the inventor of the sympiesometer, patented in 1818. Adie's sympiesometer is a glass tube filled with coloured almond oil with a gas bulb filled with hydrogen at the top. A thermometer registers the temperature and the sliding brass scale of pressures slides against a fixed scale of temperatures. Alexander Adie patented his design of a special barometer in 1818. It was more portable than a mercury barometer and could be used at sea or for measuring the height of mountains: air pressure decreases by height at a known constant. Captain Fitzroy took one on his famous Beagle voyage.
