With a patent awarded in 1856 (S. Wilcox and O.M. Stillman), George Babcock and Stephen Wilcox joined forces to design and market a boiler that increased heating surfaces for better efficiency and was both effective and safe.

B&W is established in Providence, Rhode Island, when George H. Babcock, Stephen Wilcox, Jr., and Joseph P. Manton form Babcock, Wilcox and Company to manufacture and market a water-tube steam boiler. This invention patented by Babcock and Wilcox marks the beginning of and set the standard for safe, reliable steam-generated power.

B&W sells its first boiler to Carpenter & Cross of Providence for the Valley Worsted Mills.

Babcock moves to New York City where he opens an office on Broadway.

As a salesman for Hope Iron Works, Wilcox also moves to New York City and leases an office at 44 Cortlandt Street, which would later become the company’s headquarters.

In the first year of the new decade, Joseph Manton withdrew from his partnership with Babcock and Wilcox. His departure, however, was only a minor setback, for the company continued to gain momentum. B&W earned national recognition at Philadelphia’s sensational Centennial Exhibition.

B&W headquarters is established in New York City.

Babcock and Wilcox publish Requirements of a Perfect Steam Boiler, a simple, 12-point set of guidelines for the ideal boiler. With this document, B&W creates a reputation of excellence and an industry standard for boiler manufacture.

B&W publishes the first edition of Steam/its generation and use. To this day, Steam is the most comprehensive study of steam power available and is used as a textbook throughout the world.

Babcock and Wilcox are awarded a gold medal for their full-size, 150 horsepower cast iron front boiler specially created for the international exhibition in Philadelphia to commemorate the Centennial of American Independence. Though the initial investment was expensive, the strategic decision to showcase their boiler at the Exposition is rewarded. The public is captivated by the possibilities of the boiler and new orders begin to roll in. B&W’s first major customers: sugar refineries.

The Centennial boiler showcased in 1876 is sold to DeCastro and Donner, a sugar refinery in Brooklyn, New York. It remains in service for 24 years.

Thomas Edison orders a boiler to power his machine shop and laboratory in Menlo Park, New Jersey.

The 1880s saw the birth of the electrical age with the opening of Brush Electric Light Company in Philadelphia, and Thomas Edison’s Pearl Street station in New York City. Babcock & Wilcox equipment powered both, and the young company extended its focus to European and government applications.

Babcock is a founding member of the American Society of Mechanical Engineers, established in New York City.

Babcock becomes the first president of the newly incorporated New Jersey company, The Babcock & Wilcox Company.

Nathaniel Pratt, who would be B&W’s second president, opens the company’s first non-U.S. office in Glasgow, Scotland.

Philadelphia’s Brush Electric Light Company, illuminated by four 73-horsepower B&W boilers, is the first electricity-producing central generating station in America. Boilers are also sold to Edison Electric Light Company for the Holborn Viaduct Station in London and for the International Electric Exposition in Paris.

Thomas Edison’s Pearl Street station in New York City, operating with four B&W boilers, is the first public utility. Electric lighting becomes a reality.

The Babcock & Wilcox Company opens an office in London to pursue overseas business. From 1884 to 1887, branches are opened in Manchester, Sydney, Paris and Brussels.

Thomas Edison, who had B&W boilers in his laboratory, writes that a B&W boiler is “the best boiler God has permitted man yet to make.”

The success of the new boiler built for Wilcox’s steam yacht Reverie convinces the U.S. Navy and British Admiralty to use B&W’s marine boilers.

To follow up the successful performance at the Philadelphia Centennial Exposition 13 years earlier, a B&W boiler captures the top prize at the Exposition Universelle in Paris, France.

Babcock & Wilcox, Limited is incorporated in Britain and effectively consolidates the company’s international business with headquarters in London.

Though George Babcock and Stephen Wilcox died 19 days apart in 1893, their legacy of designing and supplying the highest-quality equipment and providing superior customer service lives on today. The 1890s signaled B&W’s first firm foothold overseas and the establishment of its marine boiler service. The company closed out the nineteenth century with new leadership, a steadfast relationship with the utility industry and a developing relationship with the U.S. Navy.

B&W establishes a Marine Department. The U.S. Navy purchases its first coal-fired water-tube marine boiler from B&W. In the coming years, this boiler is ordered for the USS Marietta, Annapolis and Chicago. The British share the U.S. Navy’s enthusiasm for B&W marine boilers, which power many British ships and help establish B&W as the leader in marine boiler production.

B&W continues to pursue global expansion as licensees are founded in France and Germany (Deutsche Babcock AG) and a branch is established in Mexico. Edwin H. Wells, the fourth president of B&W, commences his 21-year presidency, which is characterized by tremendous growth and expansion.

Vølund A/S is founded, producing heating systems and steam laundries.

William D. Hoxie, who would succeed Wells as president, introduces a completely redesigned boiler for the Alert. This marine boiler’s combustion process is revolutionary and helps establish the water-tube boiler as the standard for marine service.

B&W purchases the Stirling Consolidated Boiler Company Plant’s 65-acre facility in Barberton, Ohio. With this acquisition, the company begins production of bent-tube boilers. Only 40 years since B&W was founded, Stirling boilers were now being fabricated at up to 823 horsepower and 300 pounds pressure, or 16 times more powerful than the 1867 water-tube boiler.

From 1907 to 1909, U.S. President Teddy Roosevelt’s Great White Fleet is powered by B&W boilers.

B&W’s pioneering marine boilers triumph during World War I, powering Navy destroyer and emergency fleets. During wartime, B&W boilers were mass produced, following the landmark shop-assembly technique the company began in 1909. B&W boilers powered both maritime vessels and production facilities for all types of war materials. Research continued during this production boom as B&W’s first economizers, a significant aid in boiler efficiency, are manufactured.

Vølund A/S begins making crude oil engines for marine propulsion.

He is known for revolutionizing marine boiler standards and practices, anticipating and driving the development of high-pressure, high-efficiency stationary oil-firing units, and establishing the company’s first group insurance program “to improve the welfare and security of B&W employees.”

B&W is contracted to build the water pipe, or penstock system, for the Hoover Dam. Due to their immense size, the penstocks could not be shipped by rail, so B&W built a fabricating plant near the dam site which housed some of the largest machines ever in use at the time. Upon the dam’s completion, it was often called the “eighth wonder of the world.”

In total, 4,100 of the 5,400 major vessels constructed for the war effort were equipped with B&W boilers. Marine boilers dominated the war years, but B&W also forged ahead in research and development.
