Thomas Andrews was one of the key individuals involved in the design and construction of the RMS Titanic. He was the chief naval architect for the ship and played a significant role in overseeing its construction.
When the Titanic struck an iceberg and began to sink on April 15, 1912, Andrews did not survive the disaster. He is widely reported to have acted heroically during the evacuation process, assisting passengers and crew members to the best of his abilities.
Regarding his motivations for staying on board the sinking ship, there is no concrete evidence to suggest that he chose to remain out of guilt for the tragedy. Instead, it is more likely that he felt a strong sense of responsibility and duty to help those on board and to gain a better understanding of the ship's behavior under such dire circumstances. As the ship's architect, he may have wanted to learn from the disaster to improve future ship designs and safety measures.
It's important to note that much of what is known about Thomas Andrews' actions during the Titanic's sinking comes from survivor accounts, and the exact details of his final moments remain speculative. Nevertheless, his actions have been widely praised as he reportedly worked tirelessly to assist as many people as possible, putting others' safety before his own.
