A long-standing department of the British Museum, it has played a major role in the study of coins, paper money, medals, and related objects from around the world. Its publications and catalogues reflect the museum’s deep interest in how money and medals connect art, history, and everyday life.

by British Museum. Department of Coins and Medals, Herbert A. (Herbert Appold) Grueber
The Department of Coins and Medals is part of the British Museum rather than an individual author. It is known for collecting, studying, and publishing work on coins, medals, paper currency, and other forms of money from many cultures and periods.
The department’s name appears as the author on older museum guides and catalogues, including works connected with the museum’s numismatic collections. In that context, the author credit represents the scholarship and curatorial work of the department as an institution.
Because this is a museum department and not a single person, a personal biography and portrait do not really apply here. If you want, I can also help turn this into a shorter catalog-style note tailored for an audiobook or library listing.
