Julius Bredt (29 March 1855 – 21 September 1937) was a German organic chemist. He was the first to determine, in 1893, the correct structure of camphor. Bredt also proposed in 1924 that a double bond cannot be placed at the bridgehead of a bridged ring system, a statement now known as Bredt's rule. The rule however, has been contradicted since, by a publication 100 years later.
There is a Julius Bredt lecture in his remembrance at the RWTH Aachen University.
