The vacuum flask was invented by the Scot Sir James Dewar, while working as a scientist at Oxford University in 1892.
The first barometer was devised by Evangelista Torricelli, a student of Galileo Galilei, in 1643.
The best known safety lamps are the Davy lamp, invented by Sir Humphry Davy and the Geordie lamp, invented by George Stephenson. Both of those were invented in 1815 and have been superseded by the Gray, Muesler, Marsant, and other lamps; most later lamps are constructed on the principle discovered by Davy, that a flame enveloped in wire gauze of a certain fineness does not ignite firedamp.
