On January 23,1960 Jacques Piccard and Navy Lt. Don Walsh dove to the bottom of the Marianas Trench, the deepest spot in the Pacific Ocean. The submersible that they used was named the Trieste. Since this accomplishment, no other manned ships have attempted to reach the bottom of the Marianas Trench.
