Kennedy was born in Brookline Massachusetts on May 29th, 1917. Personally Kennedy was an adventurous young man. He was blessed with looks, money and charm. He was inspired by achievements; he looked down at failure and was driven by success. .
Nevertheless, under all that glamour, Kennedy strove for a serious life in politics. In this sense, Kennedy remained constantly aware of his political heritage, as a result, he never lost sight of his personal and family goals in that world. However, right from his earlier man hood he had enormous compilations of back and health problems. These same medical problems restrained Kennedy through out his political career, beginning with a rejection from the U.S. Army in 1941. .
In order to enter into the service Kennedy went through months of training. . Then prevailing on his father's influence in 1942 he was able to gain a posting in the U.S. Navy. Although he was unsatisfied with his responsibilities, due to the fact he was only assigned to a dull desk job with ONI. However, soon after this through his continued efforts, he was reassigned and entered combat. .
Kennedy rose to the rank of Lt. Commander of PT-109, a small craft used for night patrol in the South Pacific, and was known as a hero by rescuing members of his crew after his boat was rammed and sunk by a Japanese destroyer. During the destruction of his ship Kennedy was thrown across the ship deck on to his back. Nevertheless, even though he endured much pain, he found the strength to rescue a wounded confidant and swam three miles to a near by island. For several days Kennedy swam out to sea with no sight of rescue. Eventually after many day and nights out in the middle of the South Pacific the crew of PT-109 were rescued. Kennedy's heroic performance earned him a metal and a Purple Heart, but in the process he aggravated his back and contracted malaria. Due to his health and chronic back injuries Kennedy then became unsuitable for combat and in March 1945 he was released from duty.
