## Paul WaldenBorn 26 Jul 1863; died 24 Jan 1957 at age 93.Paul Walden was a Latvian chemist who, while teaching at Riga, discovered the Walden inversion, a reversal of stereochemical configuration that occurs in many reactions of covalent compounds (1896). Due to this discovery, Walden's name is mentioned almost in all textbooks on organic chemistry published throughout the world. Walden revealed autoracemization and put the foundations to electrochemistry of nonaqueous solutions. Walden is also known for Walden's rule, which relates the conductivity and viscosity of nonaqueous solutions.[DSB gives birth date 26 Jul 1863. EB gives birth date: New Style 14 Jul 1863 (Old Style 26 July 1863).] |
