About the Author
Dennis Graver has been a scuba instructor and instructor trainer since 1968. He has written 27 books and manuals on the subject, including four previous editions of Scuba Diving published by Human Kinetics. As director of training for the Professional Association of Diving Instructors (PADI), he designed the PADI modular scuba course and wrote the PADI Dive Manual, which revolutionized scuba instruction. During his tenure as director of education for the National Association of Underwater Instructors (NAUI), Graver wrote several diving texts and manuals, including the NAUI Open Water I Scuba Diver Course Instructor Guide. He has contributed hundreds of articles on diving to magazines such as Skin Diver, Sources, and Undercurrents as well as several NAUI technical publications.
Merging twin passions, Graver has expertly photographed many wonders under the water from the Red Sea off the coast of Egypt to the barrier reefs of Australia. He has won numerous awards from the Underwater Photographic Society, and his photos have graced the covers of numerous magazines and illustrated several diving texts and audiovisual educational programs.
Graver and his wife, Barbara, live in Camano Island, Washington.
