Who invented the thermometer and when?

The invention of the thermoscope, a thermometer like device used to measure body temperature, is usually credited to the physician Santorio Santorio in 1612.

Many argue that knowledgeable men of the day, including Galileo, collectively invented the device.

However, Santorio was the first to actually add a number system to gauge changes in temperature.
