Thomas Midgley Jr. is also a good contender:

He did this by pouring tetra-ethyl lead over his hands and then holding a cup of it under his nose and inhaling it for sixty seconds. Whilst performing this deadly demonstration he was assuring reporters of how he could repeat this practice daily without harm. He did this whilst knowing full-well the dangers of lead poisoning due to having been over-exposed to the substance a few months previous to the demonstration.&quot;
