Two studies composed by

Daniel Harrwitz

(Poland, 22.2.1821 - 2.1.1884 Italy)

More about him can be found at Wikipedia although the birthdate there is wrong according to this article at Chess Notes by Edward Winters website

where a picture of the Gravestone shows the above birthdate.

He was a strong chessplayer who played matches with Morphy, Anderssen and Staunton.
