Moore, EdD, grew up in the foothills of western North Carolina. He attended the University of North Carolina–Asheville where he received his bachelor’s degree in chemistry. He earned his master’s degree in chemistry from Furman University in Greenville, South Carolina. After a stint in the United States Army, he decided to try his hand at teaching. In 1971 he joined the chemistry faculty of Stephen F. Austin State University in Nacogdoches, Texas, where he still teaches chemistry. In 1985 he went back to school part time and in 1991 received his doctorate in education from Texas A&M University. For the past several years he has been the co-editor (along with one of his former students) of the “Chemistry for Kids” feature of The Journal of Chemical Education. In 2003 his fi rst book, Chemistry For Dummies, was published by Wiley, soon to be followed by Chemistry Made Simple (Broadway) and Chemistry Essentials For Dummies (Wiley). John enjoys cooking and making custom knife handles from exotic woods. Richard H. Langley, PhD, grew up in southwestern Ohio. He attended Miami University in Oxford, Ohio, where he received bachelor’s degrees in chemistry and in mineralogy and a master’s degree in chemistry. His next stop was the University of Nebraska in Lincoln, Nebraska, where he received his doctorate in chemistry. Afterwards he took a postdoctoral position at Arizona State University in Tempe, Arizona, followed by a visiting assistant professor position at the University of Wisconsin–River Falls. In 1982 he moved to Stephen F. Austin State University. For the past several years he and John have been graders for the free-response portion of the AP Chemistry Exam. He and John have collaborated on several writing projects, including 5 Steps to a Five AP Chemistry and Chemistry for the Utterly Confused (both published by McGraw-Hill).
