Fact 1: Who invented the thermometer? Taking the temperature of a patient
provides clues to the onset of infection or inflammation. Any change in a
patient's temperature may indicate if the treatment being used is actually
working. A body temperature of 98.6 degrees Fahrenheit or 37 degrees Celsius is
Fact 2: Who invented the thermometer? The thermometer was invented by
Daniel Gabriel Fahrenheit in 1714 during the Industrial Revolution era of
inventions (1700 - 1860).
Fact 3: Who invented the thermometer? In 1664 the Medici family, centered
in Florence, Italy, sponsored the construction of the meteorological device
known as the Little Florentine Thermometer which was used to collect daily
temperature observations creating the first European weather service.
Fact 4: Who invented the thermometer? Prior to the invention of
thermometer in 1714, a device known as a thermoscope had been invented by
Galileo Galilei (1564 - 1664) in 1593 that allowed temperature variations to be
measured. The Galileo Thermometer was limited as an exact temperature in degrees
could not be measured.
Fact 5: Who invented the thermometer? In 1612, the Italian inventor
Santorio Santorio (1561 - 1636) invented the first clinical thermometer that was
designed to be placed in a patient's mouth for the purpose of taking
temperature. Santorio Santorio was the first inventor to place a numerical scale
on his thermoscope.
Fact 6: Who invented the thermometer? In 1654 the Italian scientist
Ferdinand II, Grand duke of Tuscany (1610-1670), invented the sealed
liquid-in-glass thermometer, which had an alcohol filling. His thermometer,
together with the devices invented by Galileo Galilei and Santorio, were
inaccurate and there was no standardised scale in use.
Fact 7: Who invented the thermometer? Gabriel Fahrenheit was the first
to make a thermometer using mercury. Improved glassworking techniques together
with the more predictable expansion of mercury led to the first Standard
Thermometer Scale and a much more accurate device.
Fact 8: Who invented the thermometer? The inventor of modern thermometer, Daniel Gabriel Fahrenheit, was
a German although he was born on May 24, 1686 in Danzig (Gdansk), Poland,
but lived for nearly all his his life in the Dutch Republic. He died on September 16, 1736
in The Hague, Holland.
Fact 9: Who invented the thermometer? The early years of Gabriel Fahrenheit were spent in Danzig (Gdansk), Poland.
His father's name was Daniel Fahrenheit who was a trader who moved around the
cities of the Hanseatic League a confederation of merchant guilds established by
the German House of Hanse.
Fact 10: Who invented the thermometer? His mother's name was Concordia
Schumann Fahrenheit. Gabriel was the eldest of a family of 5 children (2 boys
and 3 girls).
Fact 11: Who invented the thermometer? Gabriel Fahrenheit was educated at
home but tragedy struck the family in 1701 when both of his parents died after
consuming deadly poisonous mushrooms. known as Dead Cap.
Fact 12: Who invented the thermometer? At the age of 15 years old Gabriel
Fahrenheit was sent as an apprentice to a merchant who taught him accounting and
sent him to Amsterdam to complete his apprenticeship.
Fact 13: Who invented the thermometer? Gabriel Fahrenheit wasn't
interested in becoming a merchant. He had developed a passion for science and
inventions. He neglected his training and punished by being ordered to leave
Amsterdam. He gave up the apprenticeship and began travelling around Europe
visiting various cities including Berlin, Leipzig, Dresden and Copenhagen.
Fact 14: Who invented the thermometer? Gabriel Fahrenheit was fascinated
by the invention known as the Little Florentine Thermometer. He began to
formulate a plan to manufacture and sell this type of meteorological thermometer
together with barometers, altimeters and hydrometers.
Fact 15: Who invented the thermometer? In 1708, whilst he was in
Copenhagen, Gabriel Fahrenheit met a Danish astronomer called Ole Romer (1644 -
1710). Ole Romer used a mixture of alcohol and water, in the form of wine,
creating the spirit-of-wine thermometer. Ole Romer had developed one of the
first calibrated temperature scales that was based on the freezing point of pure
water being 7.5 degrees and the boiling point of water as 60 degrees.
Fact 16: Who invented the thermometer? Gabriel Fahrenheit adopted the
Romer method which had used a calibration with two fixed points - the melting
temperature of ice and human body. Gabriel Fahrenheit went on to improve the
invention using the newly discovered fixed points to devise the first standard
temperature scale for his thermometer ranging from 0 to 212 degrees.
Fact 17: Who invented the thermometer? Gabriel Fahrenheit invented the
mercury thermometer in 1714 replacing the alcohol (wine) with mercury which led
to the invention of the mercury thermometer. Mercury was easily visible, more
durable and could measure temperature quickly and precisely.
Fact 18: Who invented the thermometer? In 1724 Gabriel invented the
Fahrenheit Scale, that we use to this day. He divided the freezing and boiling
points of water into 180 degrees and chose 32 degrees as the the figure for the
lower fixed point. The point of 32 degrees produced a scale that would not
fall below zero even when Gabriel Fahrenheit measured the lowest possible
temperatures that he could produce in his laboratory using a mixture of ice,
salt and water.
Fact 19: Who invented the thermometer? Following his invention of the
famous Fahrenheit scale, Gabriel Fahrenheit elected a Fellow of the Royal
Society in recognition for his achievement.
Fact 20: Who invented the thermometer? Gabriel Fahrenheit never married
and died on September 16, 1736 in The Hague.
Fact 21: Who invented the thermometer? In 1742, six years after the death
of Gabriel Fahrenheit, a Swedish scientist named Anders Celsius (1701-1744)
devised a thermometer scale dividing the freezing and boiling points of water
into 100 degrees. Anders Celsius chose 0 degrees for the boiling point of water,
and 100 degrees for the freezing point but a year later, Jean Pierre Cristin
(1683-1755) inverted the Celsius scale to produce the Centigrade scale used
today (freezing point 0°, boiling point 100°) which we use to this day.
Fact 22: Who invented the thermometer? In 1848 Sir William Thomson, Lord
Kelvin of Scotland (1824 - 1907) proposed the absolute temperature scale or
Kelvin Scale with zero degrees being the theoretical lowest temperature possible
where molecular motion ceases.
