Mercury filled medical thermometer
Today it's hard to find a medical thermometer that isn't digital. And certainly no mercury filled thermometers, which are banned from sale by many governments around the world.
The first recorded thermometer was produced around 1612 by the Italian, Santorio Santorio (1561-1636), one of a group of Venetian scientists. The mercury-in-glass thermometer was invented in 1714 by physicist Daniel Gabriel Fahrenheit in Amsterdam.
