Industry Mourns Don Brookfield Sr.


Don Brookfield Sr., founder of Brookfield Engineering Laboratories, Inc., Middleboro, MA, passed away May 24 away after an extended illness.
A graduate of MIT, Mr. Brookfield first came across viscometers when he and his father, Gordon W. Brookfield, were planning to buy one to measure the fluid and physical characteristics of synthetic resins. He told his father, “I can build a better one,” and by 1934, Mr. Brookfield had sold his first working dial reading viscometer. By 1939, he was devoting his full-time efforts to developing viscometers, consistently improving upon his designs to meet the growing needs for viscosity measurement. The American Standard for Testing and Materials (ASTM) developed standards for viscosity measurement using the Brookfield Dial-Reading Synchro-Electric Viscometer. Today, Brookfield Engineering Laboratories has offices in the U.K. and Germany, and distributors in more than 60 countries.
In 1998, David Brookfield was named president and Donald Brookfield Jr. executive vice president of Brookfield Engineering Laboratories.
Outside of his work on viscometers, Mr. Brookfield worked on other innovations during World War II, such as the cathodes at the heart of airborne radar, coaxial connectors for radio research at Harvard and MIT and other defense components.
