The Air and Waste Management Association (AWMA) celebrated its 100th anniversary last year. Originally called the International Association for the Prevention of Smoke, the group held its first meeting in Milwaukee in 1907 and became a leading voice that called for reductions in emissions from automobiles, locomotives, steamboats and industrial stacks. Other names it bore during its history included Smoke Prevention Association and Air Pollution Control Association. The group has long been instrumental in disseminating scientific data about air pollution and hazardous waste.
