We thank our colleagues, Allan Clements, Lizzie Hubbard and Valmai Firth, with whom we worked on the 5th edition of The Essential Chemical Industry for their continued support and help as we developed it to this web version.
Over 100 scientists from universities, research institutes and industry commented on various parts of the 5th edition and their help is recognized under Consultants. Many of these also helped us with the web version and others, named separately contributed specifically to this version.
We have been helped enormously by many companies, both experts in their media centres and others, who have helped us with over 220 photographs and diagrams. Companies provided recent photographs to illustrate specific points raised in the text and individuals contributed to the accounts of the chemical industry and the uses of specific products. All the photographs are acknowledged separately. All of the illustrations, most of them new and produced for us by our indefatigable colleague, Mike Dunn, have been scrutinised by the industrial experts.
Without in any way diminishing the role played by the consultants, we wish to acknowledge here the contribution of Harold Wittcoff, the doyen of books related to the chemical industry, and of Henry Heikkinen, one of the finest scholars in chemical education, both for their encouragement but also for their continual founts of wisdom and good cheer. One of us (DW) wishes to thank Rupert Waddington for editing his deathly prose in the first two major sections of the site.
And a special thanks goes to Kevin Swift (Chief Economist and Managing Director) and to Smita Bhatia (Director, Chemistry and Industry Dynamics) of the American Chemical Council who gave us much time and expertise with US data and information, work we feel sure has made this version stronger.
This web site would not have seen light of day without the work of Marek Lichtarowicz of Leckhampton Computers Ltd who not only gave advice throughout the project but also taught us very patiently the intricacies and the many benefits of the system.
Finally we wish to thank Paul Jukes, formerly of Arkema, whose infectious enthusiasm for the 5th edition and the funding he helped to provide, laid the foundation for this web edition.
We have been helped by a myriad of experts but any errors are still ours.
