Asking my son who is an art authority... will repost here tomorrow.
In 1979 the auction house Sotheby's sold Frederic Church's "Icebergs," making it the first American painting to sell for more than $1 million. (It made $2.5 million.)

Other American artists who have since had paintings sold for more than that are Jackson Pollock, Winslow Homer and Mary Cassatt.
