POTSDAM -- Clarkson University Trustee Carl B. Mack and 1964 alumnus William A. Wallace have been named "Top-25 Newsmakers" by Engineering News-Record (ENR).

ENR lauded Carl Mack for his work as the executive director of the National Society of Black Engineers, tripling NSBE membership and launching free summer engineering camps, which have drawn more than 9,500 minority middle and elementary-school students, as young as third-graders, since 2005. Last year, the camps were conducted in 10 cities, some with as many as 700 participants.

Mack has been a member of the Clarkson University board of trustees since 2011, now serving on the external affairs and finance and budget committees. He is a graduate and distinguished engineering fellow of Mississippi State University, where he received a bachelor of science degree in mechanical engineering. In 2010, he was awarded an honorary doctor of science degree from Clarkson.

ENR praised William Wallace, a chemical engineer, for his work as the primary designer of the Envision Sustainable Infrastructure Rating System.

Envision takes a holistic view of infrastructure projects, using a multi-tiered, credit-award approach based on resource use, operational resilience, eco-system restoration, life-cycle costs and return on investment, among other measures.

ENR says that Wallace was key to integrating the systems to produce a more functional and less complex tool. Released in 2012, the system is still in its infancy but growing steadily in use among public works departments and engineering professionals.

Wallace graduated from Clarkson in 1964 with a bachelor of science degree in chemical engineering. He has been a member of Clarkson's Wallace H. Coulter School of Engineering Advisory Council.

The pair were honored at an ENR gala of more than 1,000 construction leaders in New York City on April 3.
