With Titanic’s sinking, U.S. Senator William Alden Smith saw this as an opportunity to investigate marine safety issues. Smith, a Republican Senator from Michigan, had experience in investigating railroad safety issues. Smith believed due to the sensational nature of this disaster that rapid action was needed. Another concern was that many of the witnesses-surviving passengers and crew-would disperse and return home. On 17 April 1912, Smith proposed that a hearing be done to investigate the sinking. President Taft, who lost his friend and military advisor Archibald Butt in the sinking, concurred. A U.S. naval escort was set up for Carpathia to make sure no one left before it docked.
Smith, accompanied by Francis G. Newlands and other officials traveled to New York and were there when Carpathia docked in New York. They boarded the ship and served subpoenas on J.Bruce Ismay and on surviving officers and crew. The hearings began on 19 April 1912 at the Waldorf-Astoria Hotel in New York and later moved to Washington D.C. The hearings, with many recesses in-between, would run for 18 days till May 25, 1912.
