Sandburg has described the genesis of the poem. At a time when he was carrying a book of Japanese Haiku, he went to interview a juvenile court judge, and he had cut through Grant Park and saw the fog over Chicago harbor. He had certainly seen many fogs before, but this time he had to wait forty minutes for the judge, and he only had a piece of newsprint handy, so he decided to create an "American Haiku".
I remember the emotion with which I first read many of these poems ... That first conviction of beauty and power returns to me as I read them again. This is speech torn out of the heart, because the loveliness of ... a fog coming on "little cat feet,"—the incommunicable loveliness of the earth, of life—is too keen to be borne ....
In 1959 and 1960, Bette Davis and her husband Gary Merrill toured the nation, putting on The World of Carl Sandburg, a dramatic staged reading of selected Sandburg poetry and prose, culminating in a one-month run on Broadway (with Leif Erickson instead of Merrill). One review described highlights of Davis's performance, including:

The poem was once loosely paraphrased on a 2008 episode of The McLaughlin Group during which host John Mclaughlin and conservative commentator Pat Buchanan discussed the candidacy of 2008 Republican Presidential nominee John McCain. This exchange was later revisited when Andrew WK included a version of the conversation in a rock anthem song he composed which was featured on Public Radio International.
