Daniel Deronda Berolzheimer (June 30, 1877 – August 24, 1952), of New York City, was a philatelist who was named to the Hall of Fame of the American Philatelic Society.
Berolzheimer had a number of postage stamp collections, but specialized in the collection and study of postal stationery, including postal cards and postal envelopes. Because of Berolzheimer's background as a chemist, he was able to study, and write on, variations of paper, inks, and color characteristics of the stationery.
Along with Victor Berthold and Julius (John) Murray Bartels, he was known as one of the “three B’s” of postal stationery.
Berolzheimer wrote numerous articles on postal stationery and authored a column in Stamps magazine. He was also a consultant on postal stationery to the Scott's Specialized Catalogue of United States Stamps. He also authored the Bartels Postal Card Catalogue and served as advisory editor of the Thorp-Bartels Catalogue.
Because of his expertise, Berolzheimer served on the expert committee of the Philatelic Foundation.
