Underwater Man: His Evolution and Explorations

The Edwin A. Link lectures are made possible by grants from the
Link Foundation in honor of its founder, Edwin A. Link, engineer,
inventor, and explorer. They are administered by the Smithsonian
Institution in cooperation with the United States Office of
Education.
This sixth lecture was delivered on 17 February 1969, at the
Smithsonian Institution's National Museum of Natural History,
Washington, D. C. The two speakers used personal experiences
in underwater marine explorations to describe the evolution of
man's involvement in underseas activities and the importance
of the seas to mankind.
