What American poet is known for his experimental use of syntax and for frequently omitting capital letters and punctuation in works like "anyone lived in a pretty how town"?

e.e. cummings

The lowercase styling of Cummings’s name was popularized by his publishers; the poet himself used different forms and often signed with capitals. In his poems, unconventional syntax, punctuation, capitalization, and typography make the page part of the work’s meaning.
