By 1901 the National Casket Company had acquired further businesses in
Philadelphia, Pennsylvania;
Nashville, Tennessee;
Louisville, Kentucky;
Indianapolis, Indiana;
Chicago, Illinois; and
New Haven, Connecticut. Chappell died in a motor car accident in July 1909, and afterward, William D. Hamilton of Pittsburgh managed the company. It was one of the leading advertisers in the
Confederate Veteran and had won first prize at a Southern heritage parade in 1908 with a float featuring two teenagers dressed as a
Confederate officer and his plantation-owning wife standing next to a casket. In 1912 the company advertised "Confederate gray
broadcloth-covered caskets" for the burial of Confederate Army veterans. In addition to caskets, the National Casket Company made other funeral equipment, including
hearses and
embalming fluid. In 1912 two of the company's embalmers traveled from Boston to
Halifax to assist with the reception of bodies carried by the
CS Mackay-Bennett from the scene of the
sinking of the Titanic. Baseball player
Harry Fritz was an associate for the company after retiring from sport in 1915. In 1916 a flood in
Asheville, North Carolina, inundated a company warehouse, leading to caskets floating in the floodwater next to the bodies of victims of the disaster. In 1919 the company purchased a warehouse at
Scottdale, Pennsylvania, from the United States Casket Company (the site went on to close in 1971). Philip B. Heintz of Boston took over from Hamilton as manager of the National Casket Company in 1922. In his 1924
A Magician Among Spirits the escapologist
Harry Houdini recalled successfully escaping from a casket made by the company. The company had challenged Houdini to make an escape from a heavy-duty hickory coffin whose lid had been secured with screws. After the 1929 death of
Ol' Rip the Horned Toad the National Casket Company provided a casket for display of his body. In 1944 one of the company's suppliers was the piano maker
Steinway & Sons, who had diversified into coffin manufacture. The National Casket Company was a pioneer in the use of fiberglass-reinforced plastic coffins in lieu of more expensive bronze versions. By 1951 the National Casket Company was the largest manufacturer of caskets and other funeral supplies in the world. It had branches in 34 cities east of the
Rocky Mountains and operated 15 factories. At this time the president of the company was Howard M. Tuttle, son of John F. Tuttle, and the general manager and first vice-president was Leo Stein. The company remained headquartered in New York state but its main office facility was in Boston. The Oneida factory closed in 1967, its equipment having become outdated (the building burned down in 2006). == Merger with Walco and decline ==
