You may recognize Dr. Robert Ballard as the oceanographer who discovered the wreckage of the Titanic.But he is also responsible for discoveries that rewrote science books. Prior to speaking at Elizabethtown College on Wednesday night, he sat down with WGAL’s Anne Shannon.Ballard loves sharing his life of discovery. He wanted to be an explorer since he was a boy."At age 12, I went to the movie and saw the movie '20,000 Leagues Under the Sea.' And that was it. I wanted to be Captain Nemo," he said.Ballard followed that dream and in 1985, his team discovered the Titanic. It was an emotional moment."Because all these lost souls had been found. We were at the spot. It's like Gettysburg. The spot speaks," he said.Ballard would go on to find numerous shipwrecks, but his greatest achievement: "We found a whole other life system that was living not off the sun, but the energy of the earth itself," he said.At 79, Ballard said he's still discovering new things – even about himself. He realized late in life that he has dyslexia."It's a gift that I was able to turn into a gift," he said.Ballard believes it forced him to think differently and face failure, which he calls the greatest teacher of all."And so that's the message. Don't let them knock you down and keep you down. Get up. You'll be fine," he said.Ballard is set to lead his 106th expedition. He'll map the waters surrounding the U.S. coastline.He calls it Lois and Clark. It will be led by a team of mostly female explorers.
