Very few American companies survive to celebrate more than 160 years of operation. Companies like The New York Times, Brooks Brothers, DuPont, Merriam-Webster, Colgate, American Express, Corning Glass, Colt Firearms, Procter and Gamble, and McGill Smith Punshon, Inc. learned to adapt. DuPont no longer supplies gunpowder to the United States military. Instead, it ranks as one of Americas leaders in research development. When Colgate was founded in the early 19th century, it specialized exclusively in soap and candles. Today, Colgates portfolio features more than 800 products distributed worldwide.Those same qualities of principle and innovation are true for McGill Smith Punshon, Inc., a company that, from its founding, has met the needs of a growing city with integrity, innovation, and creativity. Since 1856, McGill Smith Punshon, Inc. has survived a civil war, two world wars, economic depressions, and great changes in the professions of surveying, civil engineering, architecture, and landscape architecture.Today, its work is indelibly imprinted on the built environment and landscape of America.Examples of McGill Smith Punshon, Inc. (MSP) projects are found not just in the Greater Cincinnati region, but throughout the entire country and even parts of Canada. The projects MSP has been involved with represent every major time period in American history, starting with the urban center development of the mid-1800s, the early and late suburbanization movements of the late 19th and mid-20th century, and the modernization movements of the late 1900s. Its history overlaps transportation innovations and reveals the ever-changing civil engineering needs of the country. MSPs story also follows the growth of landscape architecture as these practices developed in the United States. McGill Smith Punshon, Inc. can trace its roots back to 1856, and a single individual, Joseph Earnshaw, the founder of the Joseph Earnshaw Engineering Firm. 9
