A further, most important, motivation and purpose of this meeting was 

 to develop an awareness — among those in related disciplines — of the many scientifically 

 rewarding and technologically important problems still extant and the new ones that 

 seem to arise faster than the classical ones are solved. In this way, it is hoped that 

 additional activity in classical Hydrodynamics will be stimulated in this country and, 

 as a consequence, increase the scientific potential ultimately needed in support of Naval 

 problems. 



During the early planning stages, as the scope and objectives began emerging 

 clearly, there sprung up a spontaneous desire on the part of his colleagues, past and 

 present, to choose the occasion of this first Symposium on Naval Hydrodynamics to 

 honor Captain Harold E. Saunders, USN (Ret.) for his contributions in creating a stimu- 

 lating atmosphere for research in Hydrodynamics in the U. S. Navy. Capt. Saunders, 

 through his foresight and inexhaustible energy, can be credited — perhaps more than any 

 other man — with the existence in the U. S. Navy at the start of World War II of the 

 facilities and environment so urgently needed for dealing with the hydrodynamic 

 problems suddenly faced by the Fleet and which had been neglected in prior years. In 

 spite of, or perhaps because of, his uncompromising demand for the ultimate detailed 

 solution of the most difficult problem, he holds the respect and affection of all those 

 who know and worked with him, whether or not they agreed with him in all matters. 

 While Capt. Saunders has received well-deserved honors from the U. S. Navy and 

 various institutions, it was a privilege to make the Symposium banquet the occasion of 

 a more personal appreciation by his friends and scientific colleagues. The testimonial, 

 delivered by RAdm. A. G. Mumma, USN, Chief of the Bureau of Ships, is reproduced 

 as an important part of this volume. 



It is our privilege to express the appreciation of the Office of Naval Research 

 and the National Academy of Sciences to the authors, each an authority in his field, 

 for their graciousness in accepting our invitations. Special thanks are due Prof. L. M. 

 Milne-Thomson for his willingness to accept the difficult assignment of presenting a 

 critique of the theoretical foundations of the field. 



Finally, it is a pleasure to acknowledge the contributions of the members of 

 the team directly responsible for the Symposium. The technical program and physical 

 arrangements for the formal sessions were the responsibility of the ONR Mechanics 

 Branch. The many administrative details, the banquet, and arrangements for personal 

 comfort were kindly undertaken by the National Research Council. Special recognition 

 is deserved by Mr. Marshall P. Tulin for his contributions toward developing and formu- 

 lating the technical program, Dr. Frederick S. Sherman for undertaking the task of 

 editing the proceedings, Cdr. Waldo S. Simons, USN, and Mr. John M. Crowley and 

 Dr. Howard M. Berger for the physical environment and aids and the Mrs. Lucille 

 Rittue, Yetta Hassin and Audrey Steinman for their good humored secretarial assistance 

 throughout the trying year leading up to the meeting. All are members of the ONR 

 Mechanics Branch. Special thanks are also extended to Mrs. Alice Mclntyre and Mrs. 

 Catherine M. Parrish of the NAS-NRC for their assistance to the Executive Secretary, 

 NRC Physical Sciences Division.
