Lectures

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.

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
and designed to enrich the literature on the history of aerospace
and oceanography, and to contribute to "the increase and diffusion of
knowledge among men."

As a further tribute to the inventive genius of Mr. Link, it is appropriate
that this, the seventh of the Link Lecture Series, be devoted to
his development of the newest and most practical underwater work
vehicle. The Johnson-Sea-Link submersible has just been commissioned
and promises a great advancement in the area of marine research.
For this achievement, also, we give immeasurable credit to
J. Seward Johnson, whose financial contributions have helped in its
construction, and will continue to help in its research operations.
