Mausoleums became popular for the wealthy during the rural cemetery movement and numerous mausoleums dot Elmwood Cemetery grounds. Two mausoleums of distinction are the Meyer mausoleum and the Johnson Mausoleum.
Christopher Meyer was a German immigrant who invented the first steam boiler for rubber processing. He helped start the New Brunswick Rubber Company, opened the Meyer Rubber Company in Milltown, New Jersey in 1843, and co-founded the North British Rubber Company, a forerunner of the Michelin Company.
James Wood Johnson and the estate Robert Wood Johnson, two of the 3 founding brothers of Johnson and Johnson, erected Greek Revival Mausoleum in 1911 for the entombment of the Johnson family. The mausoleum, planned by New York Architect, William Henry Deacy, was designed to resemble a Greek Temple.
