who is the author of this poem?

the yellow fog that rubs its back
upon the windowpanes,
the yellow smoke that rubs its muzzle on the windowpanes
licked its tongue into the corner of the evening
lingered upon the pools that stand in drains
let fall upon its back the soot that falls from chimneys
slipped by the terrace
made a sudden leap
and seeing that it was a soft October night
curled once about the house and fell asleep
