Archibald Gracie IV (January 15, 1858 – December 4, 1912) was an American writer, soldier, amateur historian, real estate investor, and passenger aboard RMS Titanic.

Gracie survived the sinking of the Titanic by climbing aboard an overturned collapsible lifeboat and wrote a popular book about the disaster.

His father, Archibald Gracie III, had been an officer with the Confederate States Army during the American Civil War; in 1862, he was promoted to brigadier general.

He spent a number of years researching the battle and eventually wrote a book titled The Truth about Chickamauga, which was published in 1911.

They included the writer Helen Churchill Candee, 52,[4] and three sisters, née Lamson, who were also in their fifties: Charlotte Appleton,[5] Malvina Cornell,[6] and Caroline Brown.

[9] He also spent time reading books he had found in the first-class library and discussing the Civil War with the businessman Isidor Straus.

Gracie was known among the other first-class passengers as a tireless raconteur who had an inexhaustible supply of stories about Chickamauga and the Civil War in general.

On April 14, Gracie decided that he had neglected his health and spent some time in physical exercise on the squash courts and in the ship's swimming pool.

He sat up, realized the ship's engines were no longer moving, and partially dressed, putting on a Norfolk jacket over his regular clothes.

Once the last regular lifeboat had been launched at 1:55 am on the 15th, Gracie and Smith assisted Lightoller and others in freeing the four Engelhardt collapsible boats that were stored atop the crew quarters and attached to the roof by heavy cords and canvas lashings.

Oh the agony of it.As the fore part of the ship dipped below the surface and the water rushed towards them, Gracie jumped with the wave, caught a handhold, and pulled himself up to the roof of the bridge.

"[10] As the night wore on, the exhausted, freezing, and soaking wet men aboard the overturned Collapsible "B" found it almost impossible to remain on the slick keel.

Gracie later wrote that over half the men who had originally reached the collapsible either died from exhaustion or cold and slipped off the upturned keel during the night.

[11][12] Gracie never recovered from the ordeal he endured in the sinking of Titanic; as a diabetic, his health was severely affected by the hypothermia and physical injuries he suffered.

[17] Constance lost her share of the estate in 1917 in the failure of a brokerage house and had to be financially supported by the father-in-law of her late daughter.
