Dewar benzene: Bicyclo[2.2.0]hexa-2,5-diene; a nonaromatic constitutional isomer of benzene. Named for Sir James Dewar (British chemist and physicist; inventor of the Dewar flask, which is the basic technology of the modern thermos bottle) who (incorrectly) proposed this structure for benzene in 1867.
