Dorothy Goetz (February 5, 1892 – July 17, 1912) was the first wife of the famous songwriter, Irving Berlin. She was born in Buffalo, New York to Edward H. and Mary T. Goetz.
Dorothy was nineteen years old when she met Berlin in New York City where her older brother singer and lyricist Ray Goetz (and later a leading Broadway producer) had been collaborating on some tunes with Berlin. Goetz, who was a singer, wanted to meet Berlin in order to obtain one of his songs to sing. At that meeting she got into a brawl with another singer who also wanted the song. Berlin gave the song to the other singer but asked Goetz out on a date. Within a few weeks, they were deeply in love. Berlin proposed marriage some weeks after their meeting. They were married in February 1912, and went to Cuba on their honeymoon.
Shortly after their arrival an outbreak of typhoid occurred. Upon returning to New York, Dorothy became sick. Her illness worsened over the next few months, with doctors unable to help her, until she died on July 17.
Berlin was deeply affected by her death and for a while his songwriting was affected and he wrote several joyless songs. Five months later he decided to write about his wife's death, pouring his grief into the ballad called "When I Lost You", a simple waltz with a bittersweet harmony under the melancholy melody. Berlin insisted that the song was based on his wife's death, the only song he ever admitted was related to his own experience. He did not marry again for twelve years.
