A kudurru was a type of stone document used as a boundary stone and as a record of land grants to vassals by the Kassites and later dynasties in ancient Babylonia between the 16th and 7th centuries BC. The original kudurru would typically be stored in a temple while the person granted the land would be given a clay copy to use to confirm legal ownership. Kudurrus are often linked to what are usually called "ancient kudurrus", land grant stones from the third millennium which serve a similar purpose though the word kudurru did not emerge until the 2nd millennium.

André Michaux, also styled Andrew Michaud, was a French botanist and explorer. He is most noted for his study of North American flora. In addition Michaux collected specimens in England, Spain, France, and even Persia. His work was part of a larger European effort to gather knowledge about the natural world. Michaux's contributions include Histoire des chênes de l'Amérique and Flora Boreali-Americana which continued to be botanical references well into the 19th century. His son, François André Michaux, also became an authoritative botanist.
