An Important Video Message from the Late Capt. Don Walsh to Students Everywhere

A Message from the Late Captain Don Walsh to Students Everywhere

One of the Two Human Beings to First Visit the Deepest Part of the Ocean, Seven Miles Deep

Help Us Continue to Spread Don’s Message to Thousands of Students

In 1960, Captain Don Walsh and Jacques Piccard, became the first two human beings to reach the deepest point in the ocean, the Challenger Deep in the Pacific, seven miles deep. Such a journey was not repeated until more than five decades later.

I was fortunate to know and work with Don. Our connection went well beyond the fact that we were both submariners. We worked together to advise in the creation of a major marine science institute. I took Don to Cuba which he very much enjoyed. And we shared a strong dedication to education.

Don recorded this special video message for our next generation as part of Ocean Doctor’s 50 States Expedition, a journey to all fifty U.S. states, and territories, to educate young students about the oceans and encourage careers in science.

I have presented Don’s message in live speeches and interactive class exercises to nearly 22,000 students in person. He was deeply dedicated to reaching the next generation and encouraging careers in science and engineering.

Don passed away November 12, 2023 but his strong spirit of ocean exploration and conservation will always be with us.
