A gremlin is a mischievous folkloric creature invented at the beginning of the 20th century to originally explain malfunctions in aircraft, and later in other machinery, processes, and their operators. Depictions of these creatures vary widely. Stories about them and references to them as the causes of especially inexplicable technical and mental problems of pilots were especially popular during and after World War II.

Fremlin's was a brewery in Maidstone, Kent, England. It was established by Ralph Fremlin in 1861, who eschewed the pub trade and focused on bottled beer, on religious grounds. The beer was known for the distinctive elephant logo on the bottles. The brewery expanded to become the largest in Kent, before going into decline after being purchased by Whitbread in 1967.
