Karl Fischer (24 March 1901 – 16 April 1958) was a German chemist.{{cite web |last1=Sella |first1=Andrea |title=Karl Fischer's Titrator |url=https://www.chemistryworld.com/opinion/karl-fischers-titrator/5695.article |website=Chemistry World |publisher=Royal Society of Chemistry |access-date=3 January 2023}} In 1935 he published a method to determine trace amounts of water in samples.{{cite journal|doi=10.1002/ange.19350482605

It remains the primary method of water content determination used worldwide by government, academia and industry laboratories, including all major chemical manufacturers, refrigerant producers, and petroleum refiners.{{cite journal | doi = 10.1002/1521-3781(200006)34:3<170::AID-CIUZ170>3.0.CO;2-2 | title = Die Wasserbestimmung mit Karl-Fischer-Titration | year = 2000 | last1 = Schöffski | first1 = Katrin | journal = Chemie in unserer Zeit | volume = 34 | pages = 170–175 | issue = 3}}
