My career began as a "go-for" guy and blue print machine operator as a summer job in 1966. Though I wanted to be an aeronautical engineer, the employer was an air pollution control equipment manudacturer. I liked it. In 1970, I received a a BS degree in Mehanical Engineering from Newark College of Engineering. Besides the books mentioned, I've written over fifty technical papers and articles and consider among my colleagues some of the leading professionals in the industry who strive to keep our air clean. These publications are my way of sharing what was learned during the last nearly four decades of air pollution equipment design.
