Galileo Galilei is often credited with inventing the first thermometer in the early 17th century, although other scientists like Santorio Santorio also contributed to early developments in temperature measurement. Galileo's thermometer was a simple device using the expansion of gas to indicate temperature changes.
G.D. Johnson and E.S. Murdock are credited with inventing the K-type thermometer in 1954 for measuring high temperatures, especially in industrial settings.
Sir Thomas Allbutt, an English doctor, invented the clinical thermometer in the 19th century. His design made it easier to accurately measure and record body temperature in patients.
In 1612 the inventor Santorio Santorio became the first to put a scale on his thermometer. It was perhaps the first crude clinical thermometer as it was designed to be placed in a patients mouth for temperature taking
use a thermometer.We can feel how hot or cold something is. However, sometimes things are just too hot or cold for us to feel safely. At other times we need to know exactly how hot or cold something is. When we need to measure temperature correctly we need to use an instrument called a thermometer. This measures temperature in degrees Celsius [sometimes called centigrade] or degrees Fahrenheit. There are different types of thermometers for different situations. A medical thermometer, for example, needs to be very accurate. It measures in fractions of degrees. When we are ill, even tiny changes in temperature are important. Some thermometers use a liquid that moves up a very fine glass tube. Most room thermometers, and outdoor thermometers are like this. The liquid is either mercury [ which is poisonous] or coloured alcohol. As liquids get warmer they expand [get bigger], and move up the tube. Water expands too, but not as much as alcohol and mercury. Thermometers that might be used by small children are not made of glass. They use a digital display which lights up the temperature. Inside the displays are chemicals that change colour according to the temperature.
The modern-day thermometer was invented by Daniel Gabriel Fahrenheit in the early 18th century. He is credited with introducing the mercury thermometer and developing the Fahrenheit temperature scale that is still used in some countries today.

http://wiki.answers.com/Which_Italian_inventor_invented_the_thermometerThe Italian inventor Santorio Santorio was the first to numerically scale a device that was sensitive to changing temperatures. It was made for use in medical application during the 16th century.
The first thermometers were called thermoscopes and while several inventors invented a version of the thermoscope at the same time, Italian inventor Santorio Santorio was the first inventor to put a numerical scale on the instrument. Galileo Galilei invented a rudimentary water thermometer in 1593 which, for the first time, allowed temperature variations to be measured. In 1714, Gabriel Fahrenheit invented the first mercury thermometer, the modern thermometer.
Galileo invented an air thermometer in about 1600, but changes in atmospheric pressure made accurate measurement difficult. Liquids were quickly used instead and Gabriel Fahrenheit was the first to use alcohol (1709) and mercury (1714), in a thermometer.
Daniel FahrenheitGalileo Galilei (1564-1642) Italian physicist, invented a basic air thermometer. That is the first known inventor. But we do know that the Ancient Greeks had basic thermometers but it is unknown who made it.
