Sterling-----Printed/edited early stamp catalogs in the 1800s Deats---"As a youth, Deats started collecting postage stamps of the United States and the Confederate States of America and eventually created one of the finest collections of his era, eventually selling the collection.
Deats specialized in the collecting of United States revenue stamps, and his collection, which in 1888 included the revenue collection of Edward Boker Sterling, was unsurpassed. George L. Toppan and Alexander Holland used this collection as a basis for writing, in 1899, An Historical Reference List of the Revenue Stamps of the United States Including the Private Die Proprietary Stamps, which was re-printed in 1979 as The Boston Revenue Book.
Deats also formed one of the finest libraries of philatelic books and literature in the United States, which, in 1952, he donated to the Free Library of Philadelphia." Wikipedia
Deats and Sterling also bought many of the archives of the various stamp engraving companies as they were sold off, and saved a LOT of philatelic material. All the remainders with punch cancels, for example, and a whole lot more. Proofs, essays, high value officials on cover, and still plenty more after that.
I live in Flemington,NJ. and met Hiram Deats. I now own his office building downtown and have been lucky enough to obtain some of his Butler & Carpenter proofs. Hiram was a life long collector, historian and well respected here.
