The Scully family is steeped in Boston tradition. Founding the Boston Sand and Gravel Company, they invented and operated the first rotating cement trucks in the industry. That company was instrumental in the commercial development of Boston and its surrounding communities. Scully Signal Company was founded by Francis P. Scully in 1936. Manufacturing was originally located in Lechmere Square in Cambridge. With the invention of the Ventalarm Signal ®, an ingenious device designed to prevent spillage when filling residential oil tanks, Scully embarked on what would be a long history of innovative solutions for petrochemical transport and storage operations. The product line quickly expanded into a series of vehicle and tank equipment designed for safe, dependable, and efficient product transfer. In his lifetime, Francis P. Scully invented and patented dozens of products, many of which are still in use today.

With earned national exposure, the company moved its location to an expanded facility on Green Street in Melrose in 1954. Taking part in the electronic revolution of the late 1950's, Scully began to apply leading technology to develop electronic overfill prevention systems to suit the increasing safety needs of the petro-chemical industry. The result was Dynacheck, an automatic and continuous self-checking concept that represents a major breakthrough in safety technology. The ability of a system to always fail in a safe condition remains the basis for elaborate sensing systems even today. Scully's in-house engineering department continues to research and design products that service the needs of companies that handle, store and transport liquids.

Upon the death of the founder, Francis P. Scully I, in 1964 Robert G. Scully assumed the company reins from his father. Since then he has successfully led the company into the Information Age. Ever growing, in 1969 the company relocated to Wilmington (just 12 miles north of Boston, Mass. off Interstate 93). Within a few years, the company expanded to incorporate state-of-the-art manufacturing machinery and facilities, something Scully continually upgrades. Called upon by major oil companies in the 1970's, Scully developed systems that made the company name synonymous with overfill prevention. Scully's overfill prevention bottom loading as well as grounding systems for terminals and tank truck systems are now standard equipment at loading operations throughout the world.

The advent of the information age in the 1980's expanded the company's focus to the communications aspects of liquid transfer. Investments in engineering technology continue to produce major achievements, such as Scully's cardless SAFS® system (Scully Automated Fueling System). With its SAFS®, storage site, delivery, plus tank-vehicle communications systems, Scully is a company capable of providing solutions for an entire spectrum of liquid handling. And, through both its Wilmington headquarters and its United Kingdom subsidiary, as well as direct sales offices, representatives and distributors strategically located around the globe, Scully can, and does, supply the world market. At the dawn of a new millennium, Scully continues its 65-year tradition of developing and providing innovative, safe, dependable and efficient environmental systems for controlling fills and eliminating spills.
