Robert C. Atkins was born in Massachusetts and educated in New Jersey. He received an S.B. in chemistry from the Massachusetts Institute of Technology in 1966 and a Ph.D. in organic chemistry from the University of Wisconsin at Madison in 1970. Following a year of postdoctoral study at Columbia University he was appointed to the faculty of James Madison University, where he holds the rank of professor of chemistry. He is the author of Study Guide to Accompany Chemistry; Principles and Applications (McGraw-Hill, 1979) and the co-author (with Professor Carey) of Study Guide and Solutions Manual to Accompany Organic Chemistry (McGraw-Hill, 2000). Professor Atkins has done research in the area of pyrolysis reaction mechanisms. He also has an active interest in laboratory safety and has served for more than 25 years as his departments safety coordinator. Since 1985 Professor Atkins has also volunteered as a technical advisor to both a local and a regional hazardous materials team. Francis A. Carey is a native of Pennsylvania, educated in the public schools of Philadelphia, at Drexel University (B.S. in chemistry, 1959), and at Penn State (Ph.D. 1963). Following postdoctoral work at Harvard and military service, he was appointed to the chemistry faculty of the University of Virginia in 1966. Prior to retiring in 2000, he regularly taught the two-semester lecture courses in general chemistry and organic chemistry. With his students, Professor Carey has published over forty research papers in synthetic and mechanistic organic chemistry. In addition to this text, he is coauthor (with Robert C. Atkins) of Organic Chemistry: A Brief Course and (with Richard J. Sundberg) of Advanced Organic Chemistry, a two-volume treatment designed for graduate students and advanced undergraduates. He was a member of the Committee of Examiners of The Graduate Record Examination in Chemistry from 1993-2000. Frank and his wife Jill, who is a teacher/director of a preschool and a church organist, are the parents of Andy, Bob, and Bill and the grandparents of Riyad and Ava.
