Daniel Gabriel Fahrenheit, the originator of the era of precision thermometry. He invented the mercury thermometer (first practical, accurate thermometer) and Fahrenheit scale (first standardized<unk>  scale to be widely used). A medical/clinical thermometer showing the<unk>  of<unk>  (also known as thermometry) describes the process of measuring a current local<unk>  for immediate or later evaluation. Datasets consisting of repeated standardized<unk> s can be used to assess<unk>  trends. Some of the principles of thermometry were known to Greek philosophers of two thousand years ago. As Henry Carrington Bolton (1900) noted, the thermometer's "development from a crude toy to an instrument of precision occupied more than a century, and its early history is encumbered with erroneous statements that have been reiterated with such dogmatism that they have received the false stamp of authority." In the first decades of the 18th century in the Dutch Republic, Daniel Gabriel Fahrenheit made two revolutionary breakthroughs in the history of thermometry. He invented the mercury-in-glass thermometer (first widely used, accurate, practical thermometer) and Fahrenheit scale (first standardized<unk>  scale to be widely used).
