This is a very sad day for CNBC. Without Mark we are not as smart and we are not as funny. He will be greatly missed.
Like a lot of others at CNBC, my encounters with Mark off the set were brief, but usually memorable. When I was first came to the network I introduced myself to him and he asked me where I had worked before.
"Oh, it's too bad no one watches them," he said after I told him, and walked off.
Sometimes his abruptness was unsettling but he could be equally compassionate. He was one of the first to ask after my sister, also a reporter, who went public about her battle with breast cancer. His thoughtfulness meant a great deal to me.
