I am particularly indebted to John Purcell and Don Barnett. In the 

 face of numerous and frequent requests for data, photographs, advice 

 and explanations, time and again did Mr. Purcell produce precisely 

 •what I needed or led me to individuals w^ho could and did. Dravv^ing on 

 Mr. Barnett's wide range of experience with TRIESTE I, the STAR 

 vehicles, ALUMINAUT and the Perry vehicles, I received an education 

 in the operating and design philosophies of both private and govern- 

 ment submersible activities. 



A host of individuals provided information and photographs of their 

 submersible design and construction; specifically the following were 

 most helpful and patient in dealing with my many requests: Douglas N. 

 Privitt, General Oceanographies; Terry Thompson, T. Thompson Ltd.; 

 Donald Morcombe, Horton Maritime Exploration, Ltd.; Donald B. 

 Bline, Westinghouse Ocean Research Laboratory; Donald Saner, Lock- 

 heed Missiles and Space Corp.; Robert McGratten, Electric Boat Div., 

 Gen. Dyn. Corp.; A. Pete lanuzzi. Naval Facilities Engineering Com- 

 mand; William C. W. Haines, All Ocean Industries Corp.; CAPT Edward 

 E. Hennifen, Officer of the Chief of Naval Operations; CDR Robert F. 

 Nevin, USN and Joseph R. Vadus, Manned Undersea Technology 

 Program, NOAA; Dr. Andres Rechnitzer, Office of the Oceanographer 

 of the Navy; Roger Cook, Operations Officer, JOHNSON SEA LINK; 

 Paul Dostal, Alvin, Texas; John La Cerda and Mike Witt, Perry 

 Submarine Builders; Donald Johnson, Naval Ship Systems Command; 

 Thomas Horton, Living Sea Corp.; Robert Watts, Naval Undersea

The majority of illustrations were reproduced from various transac- 

 tions of the Marine Technology Society's annual meetings; in this 

 regard I would like to express my appreciation to the Society and Mr. 

 Robert Niblock, its former Executive Director, for granting permission 

 to reproduce its material. 



Information on non-U. S. submersibles was mainly obtained by writ- 

 ing one or several individuals from various countries who found the 

 time and patience to answer another of the many "please tell me all 

 you can about" letters that owners and operators of submersibles 

 receive. My gratitude and appreciation is extended to the Kenneth R. 

 Haigh, Admiralty Experimental Diving Unit and G. S. Henson, Vickers 

 Ltd. Shipbuilding Group of the United Kingdom; LCDR Rod Smith and 

 LT Paul LeGallis of the Canadian Armed Forces; Dr. Alexander Witte 

 and J. Haas, Bruker-Physik AG Karlsruhe, Federal Republic of West
