A Legacy of Innovation

Wesco has been delivering ingenuity to our customers for more than 100 years. From the rise of electrification in the early 1900s to the digital revolution of today, we’ve remained committed to powering progress around the world.

Innovation has been in Wesco’s DNA from the start—and even before.

The modern Wesco was founded in 1922, but the company’s roots can be traced back to the time of visionary entrepreneur, George Westinghouse (1846-1914). Acclaimed in his lifetime for his pioneering work in railroad technology, natural gas distribution, and alternating-current electrical systems, Westinghouse also worked to ensure that these technological breakthroughs reached customers all across the United States.

In fact, as early as the late 1880s, immediately after founding Westinghouse Electric and Manufacturing Company, George Westinghouse worked with regional agents of a new ‘Westinghouse Electric Supply company’ to provide natural gas and electrical power to cities, rail lines, and roads from coast to coast. Competition was fierce, and these distribution representatives worked hard on the front lines of the business to help customers understand the possibilities of emerging technologies. Whether conducting onsite analysis or interviewing people coast-to-coast about their interest in electric lighting, WESCO’s innovative instinct to serve the customer first was directly shaped by George Westinghouse himself.

Wesco: Lighting the Way

From its foundation as the distribution arm of Westinghouse, WESCO was positioned to be a leader in the supply of electrical and lighting products. In 1940, WESCO was contracted to light seven tunnels across the Pennsylvania turnpike, the first of its kind “Superhighway”. Not long after, WESCO expanded its portfolio to include consumer products including televisions, air conditioners, refrigerators, and laundry machines, as well as new electrical wiring and heating systems.
