Spelled it differently, "Lost Symbol"...33rd degree mason, and director of the Smith Institute, my dad...

The Chamberlin name is associated with the Smithsonian's National Gem Collection through Leander T. Chamberlain, who, with his wife Frances Lea Chamberlain, significantly helped build the collection after his father-in-law, Dr. Isaac Lea, bequeathed his collection. While there isn't a direct connection to a "Chamberlin Natural History Museum," Leander T. Chamberlain's efforts, along with the endowment he provided, were crucial for the growth of the Smithsonian's gem collection, which is now housed in the National Museum of Natural History. Early publishing connected to the collection includes works like the 1997 book The National Gem Collection by Jeffrey E. Post and articles detailing the collection's history, such as the one published in Earth Sciences History. 

The Chamberlain contribution to the Smithsonian's gem collection 

• The Chamberlain-Chamberlain link: Dr. Isaac Lea, a Philadelphia publisher and a collector, bequeathed his gem collection to the Smithsonian. His daughter, Frances Lea Chamberlain, continued this legacy by donating her father's collection.
• Leander T. Chamberlain's role: Her husband, Leander T. Chamberlain, became an honorary curator and contributed many specimens to the collection. He also left an endowment fund that has been used to acquire more gems over the years.
• Collection growth: While the Chamberlain endowment helped, many other significant donations, most notably the Hope Diamond from Harry Winston, Inc., have been instrumental in growing the collection into what it is today
