He was a truly genius, a brave and charismatic explorer and Titanic historian. In the late 90’s saw him the very first time in two documentaries, and these films are was good. I learned him very much things about the diving and of course about the Titanic. I was shocked when I first hearing about the disappearence of the Titan, and I prayed to Allah, bring they back in a perfect health. I’m so sorry, and my deepest and honest condolences to the family and the friends.
