Mohr, Karl Friedrich

Analytical chemistry began in the late eighteenth century with the work of French chemist Antoine-Laurent Lavoisier and others the discipline was further developed in the nineteenth century by Carl Fresenius and Karl Friedrich Mohr. As a pharmacist s apprentice in Frankfurt, Germany, Fresenius developed an extensive qualitative analysis scheme that, when it was later published, served as the first textbook of analytical chemistry. He built a laboratory at his house that opened in 1848. Here he trained students in gravimetric techniques that he had developed. Mohr developed laboratory devices such as the pinch clamp burette and the volumetric pipette. He also devised a colorimetric endpoint for silver titrations. It was his 1855 book on titrimetry, Lehrhuch der Chemisch-Analytischen Titromethode, that generated widespread interest in the technique. 

Joseph Gay-Lussac (1778-1850) seems to have been the first chemist to give the status of exact quantitative analysis method to titrimetry after his work in 1824 devoted to the determination of active chlorine, potassium hydroxide, and silver ion. Other chemists in this field must also be mentioned. We shall be content here with recalling Karl Friedrich Mohr (1800-1879) and Carl Remigius Fresenius (1818-1897).
