The Hazen Legacy
Allen Hazen, a pioneer in fluid hydraulics, developed an equation used commonly to this day by engineers all over the world in calculating a system's water flow. Allen's son, Richard, joined Alfred Sawyer in forming a place where engineers were free to pursue solutions in the best interest of clients and the public. The Hazen legacy of living by our values and advancing water science and practice continues at the firm to this day.
Richard Hazen begins private practice in New York City in 1950, convincing Alfred Sawyer to join him a year later to form Hazen and Sawyer.
