Just one I think, the U.S. Navy bathyscaphe Trieste reached the bottom in 1960. Unless you count the Japanese probe thingy in 1995.

The Japan Marine Science and Technology Center (JAMSTEC) sent an unmanned vehicle, Kaiko, to a depth of (11,911m) in the Challenger Deep, Marianas Trench. It recorded video images of fish and measured hydrostatic pressure, salinity, and temperature.

The Trieste reportedly had a tough time at the bottom of Marianas because it hit a living being which was crawling around on the bottom. It's incredible to think what might be living down there.
