The archtypal character from what many consider to be the first modern western culture novel "The history of that ingenious gentleman, Hildalgo Don Quixote de la Mancha" written by Spaniard Miguel de Cervantes Saavedra in 1605. Don Quixote was a man who, in his country retirement, some how cooked his wig reading too many books. He then sallied forth to right all wrongs in the world and made quite a mess in the attempt. He was a knight errant and the primary source for an animated film by Harold Humes titled "Don Peyote", which originally was slated to star Lord Buckley as the voice of Don Quixote. Richard Buckley Jr., in a 1992 interview with Skip E. Lowe, refers to his father as a Quixotic type character.
