AACC (American Association for Clinical Chemistry) is a leading professional society dedicated to improving healthcare through laboratory medicine. Its nearly 10,000 members are clinical laboratory professionals, physicians, research scientists, and others involved in developing tests and directing laboratory operations. AACC brings this community together with programs that advance knowledge, expertise, and innovation.
Wallace H. Coulter was an engineer, inventor, and entrepreneur who applied engineering principles to solve biomedical problems. He invented the Coulter Principle, which led to the Coulter Counter, a breakthrough device that provides clinicians and scientists with a high throughput, standardized method to count and size particles or cells as they flow through an aperture. This simple, but elegant invention revolutionized hematology and the practice of laboratory medicine, pioneered the field of flow cytometry and defined particle characterization. This innovation continues to be used today in the fields of medicine, biotechnology, and pharmaceuticals, as well as food, beverage, ceramics, cosmetics, toners and paint. Mr. Coulter received the first of his 82 patents in 1953 and started his company, Coulter Corporation. The company grew to become the world leader in cellular analysis equipment, reagents and service. It remained private until purchased by Beckman Instruments in 1997. The Wallace H. Coulter Foundation was created in 1998 to continue his life-long pursuits.
