Dresser-Rand's roots can be traced back to 1840 to Worthington, when Henry R. Worthington designed and built the first direct-acting steam pump. Later, in 1880, Solomon R. Dresser, in Bradford, Pennsylvania, received a patent for a coupling that made it possible to join sections of pipe. Also in 1880, Clark Brothers Company was founded in Belmont, New York. Clark Bros. Manufactured agricultural and timber machinery. In 1899 the Rand Drill Company, later merged with Ingersoll-Sargeant Company to form Ingersoll-Rand, began manufacturing compressors in Painted Post, New York. Also in 1899, Henry R. Worthington Company merged with Laidlaw-Dunn-Gordon Co., manufacturers of gas compressors.
