Gracie boarded the Titanic in Southampton on April 10, 1912, and was assigned first-class cabin C51.

Gracie did not fully recover from the hypothermia he suffered, and died of complications from diabetes in late 1912.

The letter was postmarked Queenstown, Ireland, one of two stops the Titanic made before sinking.
