John Borland "Jack" Thayer III (December 24th, 1894 – September 20th, 1945) was a First Class passenger on the RMS Titanic who provided several first-hand accounts of the sinking.

RMS TitanicEdit

Seventeen years old at the time, Jack Thayer boarded the Titanic with his parents, John and Marian Thayer, and a maid at Southampton on April 10, 1912.[1] Jack occupied cabin C-70 while his parents occupied C-68.[2]

Shortly after midnight on 14 April 1912, Jack noticed that he could no longer feel a breeze streaming through his half-open porthole. He did not recall feeling the ship's collision with the iceberg. He dressed and went to A Deck on the port side to see what had happened. Finding nothing, he walked to the bow, where he could faintly make out ice on the Forward Well Deck.[2]

Jack woke his parents, who accompanied him back to the port side of the ship. Noticing that the Titanic was developing a list to port, they returned to their rooms and put on warmer clothes and life vests. They returned to the deck, but Jack lost sight of his parents and after searching for them, assumed they had boarded a lifeboat.[2]

Jack soon encountered Milton Long, a fellow passenger he had met hours before over coffee. Both Milton and Jack tried to board a lifeboat but were denied because they were men. Jack recalled he saw Chief Purser McElroy shoot into the air twice during the shooting at Collapsible C. Jack then proposed to jump off the ship, as he was a good swimmer. However, Milton was not and advised Jack against it.[2]

Eventually, as the ship was sinking quickly, the two men decided to jump and attempt to swim to safety. Milton went first; it was the last time Jack ever saw him. Once in the water, Jack reached an improperly launched and overturned collapsible lifeboat. Too exhausted to save himself, he was pulled from the water.[1] He and a number of other men were able to balance on the boat for some hours. He later recalled that the cries of hundreds of people in the water reminded him of the high-pitched hum of locusts in his native Pennsylvania.[2]

After spending the night on the overturned collapsible, Jack was picked up by Lifeboat 12. He was so distraught and freezing that he did not notice his mother in nearby Lifeboat 4, nor did she notice him. Lifeboat 12 finally made its way to the rescue ship RMS Carpathia at 8:30 am[2] Jack's father did not get to a lifeboat and died.

Nearly all those who lived did so by boarding lifeboats. Jack was one of only about 40 survivors of those who jumped or fell into the water.[1]

Later lifeEdit

Thayer went on to graduate from the University of Pennsylvania. He married Lois Cassatt, daughter of Edward B. Cassatt and Emily L. Phillips. Her grandfather was Alexander Cassatt, President of the Pennsylvania Railroad. The couple had two sons, Edward and John IV, and also daughters. In 1940, he described his experiences with the Titanic's sinking in vivid detail in a self-published pamphlet; 500 copies were printed for family and friends.[1] Oceanographer Robert Ballard used it to determine the location of the Titanic and proved that the ship had split in half as it sank, contrary to popular belief.[2] Thayer's account is sometimes included jointly with the memoirs of the disaster by survivor Archibald Gracie IV in modern editions of Gracie's book Titanic: A Survivor's Story.


During World War II, both of Jack's sons enlisted in the armed services. Edward was killed in 1943 in the Pacific theatre. When the news reached Thayer, he became extremely depressed and committed suicide on September 20, 1945.[3] He was found in an automobile at 48th and Parkside Ave., his throat and wrists cut. He is buried at the Church of the Redeemer Cemetery in Bryn Mawr, Pennsylvania. Thayer was the financial vice president of the University of Pennsylvania at the time of his death. [4]

Portrayal in 2012 MiniseriesEdit

Jack Thayer appears in the 2012 Miniseries Titanic. He crashes a party in the reception and starts to dance with Georgiana Grex, who was dancing with Harry Widener.

After some time, his mother literally comes to get him. She takes Jack away, leaving Georgiana without a partner for a moment.

When the ship is sinking, Jack is denied access to a lifeboat by Fifth Officer Lowe. Marian seems to be concerned about him, as he's "just 17", but the boat is lowered without him.

Later on during the sinking, he meets up with Milton Long and decides to make a swim for it. Milton wants to slide down the side of the ship, but Jack wants to jump clear from the Titanic. His decision to jump away from the Titanic saves his life.

Following the sinking of the Titanic, he swims to Collapsible B where Seaman Davis refuses to allow him on the lifeboat saying there is no more room. After a man Mario thought was his brother dies, he lowers his body off the upturned boat and allows Jack onto the boat.

The remaining survivors including Jack, Mario, and Second Officer Lightoller are rescued by Fifth Officer Lowe and are brought aboard Lifeboat 14. Jack is then reunited with his mother Mia.
