The Jones Brothers Company was described as ìthe largest monumental works in the world, with 100,000 square feet of floor space, 300 men employed, and annual sales of $500,000 in the first two decades of the century. Products from the Jones Brothers plant include memorials of famous people as well as dozens of war monuments throughout the world. Jones Brothers also provided large granite rollers for the newspaper industry; the pulp and paper industry, notably firms such as Kimberly Clark, St. Regis and Northern; as well as the Hershey Chocolate industry, which uses granite rollers to crush cocoa beans into chocolate powder. Guardian Memorials, a well-known name in memorial stones, was established by the Jones Brothers Company in 1925 and remained its hallmark until 1975 when the Jones Brothers Company plant was closed down and the Guardian trademark was sold to the company of Beck and Beck.
Some of the Jones Brothers most famous monuments and memorials are the Green Beret Memorial, the Bringham Young Memorial, the Weymouth War Memorial in Weymouth, Mass., the Meridan War Memorial in Meridan, Conn., and the Mormon Memorial in Manchester, New York. Jones Brothers is also responsible for the creation and manufacture of memorials for the families of Woolrich, Firestone, Heinz, Hood, Hershey, Ringling, and Webb as well as countless less prominent families.
Memorials for prominent individuals include William Henry Harrison (former President of the United States), B. F. Keith (the founder of American Vaudeville), Thomas R. Marshall (former Vice President of the United States), James E. Matthews (former Vice President of Bethlehem Steel), Bowman Gray (Reynolds Tobacco Co.), John Boyle OíReilly (poet and writer), Samuel Reed (Justice of the Pennsylvania Supreme Court), Garrett Schenck (President, Great Northern Paper), Fred Wardell (President, Eureka Vacuum Cleaner), and John Weeks (former United States Secretary of War), A. E. Armstrong (Armstrong Manufacturers), Elbert Gary (United States Steel Company), Darius Miller (Chicago, Burlington and Quincy Railroad), and LeGrand Parish (President, Lima Locomotive Works).
In 1900, Jones Brothers was responsible for transporting 16 pieces of granite, thirty- eight feet long and six feet in diameter (each weighing approximately one hundred tons), as well as an additional eight pieces measuring eighteen feet long and weighing forty tons, for use as columns for St. John the Divine Cathedral in New York City. The entire project of hauling and erecting the columns took over a year to complete but was executed without a nick in the granite. Other well known monuments and memorials produced by Jones Brothers Manufacturing include the Beacon Monument at the State House in Boston, the Fort Fisher War Memorial in Fort Fisher, North Carolina, and a part of a memorial to Taras Shevchenko, an Ukrainian poet and freedom fighter, in Washington, DC. As recently as 1973, Jones Brothers was commissioned to create a memorial for Fairmont, West Virginia, to honor the coal miners who lost their lives in mine disasters. When the "Battle Monument"at West Point was in need of replacement in 1973, Jones Brothers was contacted to create the bases as well as to provide a report of the manufacturing process.
