Humber, 60, was a resident of Newton, Mass. He was divorced and had a 19-year-old son, Jordan.

Prior to the tragedy, Humber had owned Brae Burn Management for eight years. The company is a consulting firm for strategic planning and marketing and product development. It mainly provides consultations to energy and environmental industries.

Humber also served as the director of East Coast operations for Enron Wind, Enron Corp.’s wind turbine division.

He held a B.S. in mechanical engineering from RPI and an M.B.A. in finance and marketing from the Wharton Graduate School at the University of Pennsylvania.

In 1972 Humber joined the Environmental Protection Agency in its first year of operation and established its municipal waste division for waste-to-energy conversion and recycling.

Humber later advised the World Bank IFC-GEF program on environmental and independent power projects, evaluating projects in India, Jamaica, and Russia.

"I’ve been amazed at the number of people his life really had impacted. I’ve had high-level people calling all day—heads of companies, who have been crying as they spoke," Jeffrey Humber, Nicholas’s brother, told the Springfield Union-News/Sunday Republican.

Humber was also an officer in the Boston Chapter of the Association for Corporate Growth and chairman of the Technology Innovation Committee for the New England Environmental Business Council.

Two memorial services for Nicholas Humber were held in Boston and Springfield, Mass. in September following his passing.

"You relive all those years, what we went through together as brothers," Jeffrey Humber told the Springfield Union-News/Sunday Republican.

"Your whole life goes by you, a life of love and emotions and brotherly bonds that all of a sudden have disappeared. Now you are out there in life without a brother."

Since September 11, a number of Rensselaer’s international student programs such as the School of Architecture’s project in Rome have been canceled.
