Ingersoll Rand has a unique heritage in construction that dates back to the company’s founding in 1871. Simon Ingersoll invented the world’s first rock drill, and revolutionized productivity on the jobsite with the wide array of compressors, tools, and related products that followed. He built a business and an industry, with the power and tools that helped create wonders such as the Hoover Dam and monuments like Mt. Rushmore. Those who followed him continued this pioneering spirit, adding tools for every job, and new refinements to make them even more powerful, efficient, and durable.
