Perry’s has been an important source for chemical engineering information since 1934. The significant contributions of the editors who have guided preparation of the previous editions is acknowledged. These include John H. Perry (first to third editions), Robert H. Perry (fourth to sixth
editions), Cecil H. Chilton (fourth and fifth editions), and Sidney D. Kirkpatrick (fourth edition).
Ray Genereaux (DuPont) contributed to each of the first six editions, and Shelby Miller (Argonne
National Lab) worked on the second through the seventh. The current editors directed both the
sixth and seventh editions. Advances in the technology of chemical engineering have continued as
we have moved toward the twenty-first century, and this edition will carry us into that century.
