Daniel Gabriel Fahrenheit (24 May 1686 – 16 September 1736)
A household name during his lifetime and even more so in the centuries since, Daniel Gabriel Fahrenheit was a physicist, engineer, and glass blower, best known for the temperature scale bearing his name which is still used today in many countries, as well as for his improvements on the mercury thermometer (1714). Born in the Polish-Lithuanian Commonwealth, he spent most of his life in the Dutch Republic. At the age of fifteen, following the death of his parents through mushroom poisoning, Fahrenheit began training as a chemist, and his personal interest in natural science led to his studies and experimentation in the field.
