(1802–28), son of William Pinkney, a leading statesman and diplomat of his time, was born in London and reared partly there and partly in Baltimore. He edited The Marylander (1827–28), a paper which supported J.Q. Adams. When his father was attacked for his haughty manner in John Neal's Randolph (1823), the younger Pinkney challenged the novelist to a duel. Pinkney's few Poems (1825) were praised by Poe for their lyric gift but were often imitative of Byron and Tom Moore.
