The Addams Family is a fictional family created by American cartoonist Charles Addams. They originally appeared in a series of 150 standalone single-panel comics, about half of which were originally published in The New Yorker between 1938 and their creator's death in 1988. The Addams are an eccentric old-money clan who delight in the macabre and the grotesque and are seemingly unaware or unconcerned that other people find them bizarre or frightening.
