Mercury thermometer, 19th-century illustration. The original mercury-in-glass thermometer was invented in 1714 by Polish-Dutch physicist Daniel Gabriel Fahrenheit. As the temperature increases or decreases, the set volume of mercury in the glass tube expands or contracts. This property can be calibrated to fit a temperature scale, one of which was named after Fahrenheit. This illustration is from 'Physique Populaire' (Emile Desbeaux, 1891). | |
