This 25-acre parcel and 12-building campus along the Woonasquatucket River was once home to one of Providence’s premier companies, Brown and Sharpe.

In 1833 David Brown and his son opened a shop in Providence for the making and repair of watches and clocks and other precision mechanical work. Lucien Sharpe joined the business as an apprentice in 1848 and became a full partner in 1853. While Brown concentrated on mechanical problems, Sharpe provided business acumen. Together they made Brown and Sharpe into a nationally recognized machine tool producer.

Brown and Sharpe’s products were the day-to-day tools of machinists and allowed them to produce the individual parts of complex manufacturing machines. Machinists, and the products they make, constitute the foundation of precision manufacturing.

The 1850s marked the beginning of the company’s spectacular rise. Brown devoted his career to raising the standard of accuracy in machine shop operations: he built an automatic linear dividing engine so fundamentally correct in design and workmanship that it has remained in continuous service. His pocket vernier caliper (a linear measuring instrument) of 1851 has been called "the first practical tool for exact measurement which could be sold in any country at a price within the reach of the ordinary machinist." In 1861, in perhaps his most important contribution, Brown invented the modern universal milling machine for cutting spirals. This machine helped advance mass production of cheap, interchangeable, and standard, parts.

After Brown's death in 1876, Oscar J. Beale became the company's genius in the field of mechanical design. He developed a measuring machine that enabled the company to make and sell its gauges with a guarantee of accuracy to within one ten-thousandth of an inch. In 1880, he invented an automatic screw machine.

Brown and Sharpe’s success depended on and helped to advance the mechanization of daily life in the 19th century. The machine tools the company produced proved instrumental to countless automotive, aeronautic, commercial, and domestic products. Brown and Sharpe's skilled workforce contributed to the development of the automobile and aviation industries and to the emergence of the United States as a global leader in manufacturing.

Home to RI's economic development agency, Commerce RI, along with several other businesses, the ALCO complex once housed a major innovator in the history of transportation.

The Rhode Island Locomotive Works constructed this building in 1865, just as the Civil War ended, with capital invested by General Ambrose Burnside of Bristol, RI. Burnside had earned his wealth from new rifle technology he patented just before the outbreak of the Civil War. He eventually reinvested his wartime profits into the booming business of railroad transportation. The Rhode Island Locomotive Works produced railroad engines for 30 years until it joined with seven other regional locomotive manufacturers to form the American Locomotive Company, or ALCO, in 1901. ALCO became the second largest steam locomotive builder in the US, producing 75,000 engines in total, including the famous “Big Boy” locomotives, the largest and most powerful engine ever created.

In 1905, the company diversified by investing in a line of automobiles and heavy trucks, spelling the beginning of the end of the railroad's monopoly on American transportation. Always on the cutting edge of innovation, ALCO obtained the American rights to the Berliet, a high-priced French car, and moved skilled mechanics from Lyons, France to Providence. The new car, priced between a jaw-dropping $6,000 to $7,500, proved to be an immediate success, at least, from the consumer's point of view. The company actually sold “the finest car produced in the US” at a loss, due to the difficulty of getting raw materials to Providence and to having a limited distribution network. Fortunately, ALCO’s line of trucks helped stem the company’s losses. By 1913, 85% of the company’s business came from trucks and 15% from high-end cars. In 1913, the New York City Postmaster gave the company its largest single order for 80 trucks, and ALCO further diversified its offerings by producing taxi cars.

Despite these efforts, ALCO announced it was leaving the car and truck business in 1913. It shuttered its Providence factory and gave notice to its entire workforce of 1,200 employees. During WWII, ALCO diversified its offerings and manufactured 7,362 army tanks, tank destroyers, shells, and bombs, in addition to locomotives. Though it no longer produced vehicles, ALCO continued to manufacture locomotives in its Schenectady, NY plant until 1968.

In Providence, US Rubber bought the ALCO plant and absorbed it into its own multi-building complex in 1918, a story told in the following stop of this tour.
