Carl Julius Fritzsche
Carl Julius Fritzsche (born October 17, 1808 in Neustadt bei Stolpen , † June 8, 1871 ) was a German pharmacist and chemist.
Life
His parents were the official physician Christian Ferdinand Fritzsche and Juliane Christiane Wilhelmine, geb. Struve. After the death of his father-in-law Heinrich Wilhelm Struve in 1805, his father took over his pharmacy. At around the same time, Julian's brother Friedrich Adolph August Struve , the inventor of the artificial mineral water, had taken over his father-in-law's pharmacy in Dresden.
From around 1822 Carl Julius Fritzsche became a pharmacist in Dresden. From 1830 he studied chemistry and became an assistant to Eilhard Mitscherlich . In 1833 he moved to Saint Petersburg , worked at a brewery and established himself as a mineral water manufacturer. Also in 1833 he was elected a member of the Leopoldina . In 1838 he became an adjunct of the St. Petersburg Academy of Sciences, from which he received his doctorate. In 1844 he became an associate professor and in 1852 a full professor.
His fields of work included organic dyes, anthracene and picric acid , but also the modifications of tin ( tin plague ). In 1842 he taught the representation of the ammonium polysulfurets, namely the ammonium quatersulfurets, the quinquiessulfurets and the septiesulfurets, which form all crystalline magmas.
The Fritzsche Reaktiv served for a long time to detect hydrocarbons and the Fritzscheit is named after him.
