Wikipedia: Karl Fischer
(24 March – 16 April 1958) was a German chemist. In he published a method to determine trace amounts of water in samples. This method is now called Karl Fischer titration and was originally performed manually but has been automated. It remains the primary method of water content determination used worldwide by government, academia and industry laboratories, including all major chemical manufacturers and petroleum refiners.
