Benjamin A. Muncil (28 Aug 1867 – 16 Dec 1930) was an American master builder in the Adirondacks early in the 20th century. He was a major figure in the architectural development of the Adirondack Great Camps; among his many projects was Marjorie Merriweather Post's Camp Topridge, Northbrook Lodge, and White Pine Camp, a summer White House of US President Calvin Coolidge. Using only the above description and what you know about the world, "Muncil lived in two different decades." is definitely correct, incorrect, or inconclusive?
