Möbius topology has been inspiring art, music, literature, science and technology for centuries. It entered the field of chemistry in 1964 when theoretical chemist E. Heilbronner predicted that Möbius annulenes would violate the Hückel rule. They would be aromatic with 4n electrons. Many attempts by numerous chemists notwithstanding, the first Möbius annulene could not be obtained before our successful synthesis in 2003. Heilbronner's theoretical predictions were experimentally confirmed.
