Any attempt to list all the people who have contributed to the labor of developing scripts would be hopeless because the extent of good will on the part of friends and listeners has been so great. But a few general statements are in order.

John Lienhard needs to thank Carol Lienhard who has critically read almost every episode with a fine ear for what will work and what will not. She has also provided a vast effort in locating material. Most of this help is unacknowledged in the scripts.

Countless colleagues at the University of Houston have contributed helpful criticism and ideas. Only some of this is acknowledged in the scripts. Listeners provide a steady flow of interaction and commentary — more than is possible to cope with adequately or to acknowledge properly. However, it has always exerted a formative, if indirect, influence on the series.

Finally, the extensive contributions of ideas, sources, graphics, and other substantive material by members of the University of Houston Libraries are gratefully noted within individual episodes. But, beyond that, many members of the Library have generously read scripts critically and contributed widely varied expertise. Only a fraction of that effort is properly acknowledged in the scripts.

Three KUHF people deserve special mention: John Proffitt, now retired head of KUHF-FM radio, encouraged the program from its inception. Capella Tucker, retired Station Director, was first associated with Engines as its sound engineer and then as its manager. And Paul Pendergraft, former KUHF manager of the Enginesprogram and a key player who kept the program running smoothly, day by day. Paul's talent and ongoing passion for Engines can still be enjoyed as announcer.
