Thomas Andrews
Thomas Andrews was a naval architect and the Head Designer of the RMS Titanic. He boarded the ship for the maiden voyage to New York. Andrews was reporteldy last seen in the Smoking Room although this has been disputed; this story, which was published in a 1912 book (Thomas Andrews: Shipbuilder) and therefore perpetuated, came from John Stewart, a steward on the ship who in fact left the ship in boat n. 15 at approximately 1:40 a.m.
There were testimonies of sightings of Andrews after that moment. It appears that Andrews stayed in the smoking room for some time to gather his thoughts, then he continued assisting with the evacuation. At around 2:00 AM, Andrews was seen back on the boat deck. The crowd had begun to stir, but there were still women reluctant to leave the ship. To be heard and to draw attention to himself, Andrews waved his arms and announced to them in a loud voice. Another reported sighting was of Andrews frantically throwing deck chairs into the ocean for passengers to use as floating devices. Andrews then headed towards the bridge perhaps searching for Captain Smith. Andrews was last seen leaving the ship at the last moment.
