WebKonrad Julius Bredt (1855-1937) was a German organic chemist who is well known for the first determination of the correct structure of camphor in 1893. Bredt also discovered that a double bond cannot be placed at the bridgehead of a bridged ring system. The statement is today known as Bredt’s rule. Read more about the Julius Bredt Lecture here .
