looking at the continuing evolution of chemical engineering. We start with reflections on the past (pp. 2S–9S) and continue to the present, where we meet a dozen engineers in different stages of their careers (10S–21S). These profilesoffer snapshots of where chemical engineers are employed. This segues into a glimpse of the future — first, with an analysis of data on where chemical engineers are employed (22S–25S), and then with an opinion piece on refocusing chemical engineering (26S–31S).

hemical engineers are a unique b r e e d . T h ey ’re a small, elite group of engineers with a rigorous education, a thorough knowledge of chemistry, and highly developed analytical, projectmanagement and problem-solving skills. T h ey ’re t ea m p laye rs w ho are accustomed to typically getting little or no credit for the wo rk they do — which usually invo l ves anear-impossible goal with next to no bu d g e t .
But that’s about as far as you can go in generalizing chemical engineers. Given, many of them work in the chemical process industries (CPI), including chemicals and fuels. They’re also involved in newer, less-traditional industries, such as biotechnology, semiconductors, advanced materials and nanotechnology. But you’ll also find them in other

Cplaces: intellectual-property management, environmental law, public administration, venture capital firms, education, even magazine writing (See profiles following this article). One of the founders of modern chemical engineering, Arthur D. Little, wasn’t a process engineer — he was a consultant. Jack Welch, Roberto C. Goizueta and Andy Grove, who became heads of their respective organizations(General Electric, Coca-Cola and Intel), all graduated as chemical engineers. So did film personality Dolph Lundgren — in fact, he was on his way to an MIT doctorate on a Fulbright scholarship when Hollywood intercepted him. The history of chemical engineering is as diverse as the individuals themselves. Chemical engineers have been responsible for delivering just about every product we use — fromthe silicon chips in our computers, to the paper we write on, to the water we drink.“Engineering facilitates things that we take for granted in our daily life,” points out Ralph Larson, staff vice president of engineering at 3M (St. Paul, MN), who has been with the firm for 35 years. “Engineers are involved in everything from product conceptual development on the bench, through developing a processfor that particular innovation, to managing our factories, to managing the supply chain.” Although the youngest of the big engineering disciplines, chemical engineering is perhaps the toughest to chronicle. A ten-volume set couldn’t sum up all the important achieve-
