Sir Martin Frobisher (c. 1535 or 1539 – 15 November 1594) was an English seaman who made three voyages to the New World to look for the Northwest Passage. All landed in northeastern Canada, around today's Resolution Island and Frobisher Bay. On his second voyage, Frobisher found what he thought was gold ore and carried 200 tons of it home on three ships, where initial assaying determined it to be worth a profit of £5.1 per ton. Encouraged, Frobisher returned to Canada with an even larger fleet and dug several mines around Frobisher Bay. He carted 1,350 tons of the ore back where, after years of smelting, it was realized that both that batch of ore and the earlier one he had taken were worthless iron pyrite. As an English privateer/pirate, he collected riches from French ships. He was later knighted for his service in repelling the Spanish Armada in 1588.

As early as 1560 or 1561, Frobisher had formed a resolution to undertake a voyage in search of a Northwest Passage as a trade route to India and China (referred to at that time as Cathay).

Jacques-Yves Cousteau (French pronunciation: [ʒak iv kusto]; commonly known in English as Jacques Cousteau; 11 June 1910 – 25 June 1997) was a French naval officer, explorer, conservationist, filmmaker, innovator, scientist, photographer, author and researcher who studied the sea and all forms of life in water. He co-developed the Aqua-Lung, pioneered marine conservation and was a member of the Académie française. He was also known as "le Commandant Cousteau" or "Captain Cousteau".

"The sea, the great unifier, is man's only hope. Now, as never before,
the old phrase has a literal meaning: We are all in the same boat."

Cousteau was born on 11 June 1910, in Saint-André-de-Cubzac, Gironde, France to Daniel and Élisabeth Cousteau. He had one brother, Pierre-Antoine. Cousteau completed his preparatory studies at the prestigious Collège Stanislas in Paris. In 1930, he entered the École Navale and graduated as a gunnery officer. After an automobile accident cut short his career in naval aviation, Cousteau indulged his interest in the sea.
