Doris Mary Ann "Do-Do" von Kappelhoff was born in Cincinnati on 3rd April 1924. Her parents split up when she was eight.

At 12, she won $500 in a dance contest and went to Hollywood. At 14, she was involved in a near fatal car crash which severely injured her right leg ended her dreams of a dancing career. Her mother suggested singing as an alternative.

Her vocal coach arranged for her to sing on a local radio station which led to her being engaged by a local band leader, Barney Rapp. The first song Barney heard her sing was Day after Day which gave him the idea for what he thought was a much better showbiz surname than von Kappelhoff.

At 19, she began touring as singer with the Les Brown Band, where she met and, in 1941, married Al Jorden. In 1942, soon after the birth of their son, Terry, she initiated divorce proceedings, alleging violence. During the War, she entertained the troops with the Les Brown Band and, in 1944, recorded her first hit, Sentimental Journey.

In 1946 she met George Weidler, a sax player with the Les Brown Band. They married but were divorced eight months later.

In 1948, she made her first film Romance on the High Seas. He song from the movie, It's Magic, was nominated for an Academy Award and became her first solo million-seller. While filming, she met Marty Melcher who become her agent. In 1951, they married.

in 1953, the movie Calamity Jane, produced Doris' second solo million-selling recording, Secret Love. This began a string of box-office movie hits, including Love Me or Leave, The Man Who Knew Too Much, The Pyjama Game and Teacher's Pet. At the same time, Doris had major record successes including A Guy Is a Guy and Que Sera Sera.

Around 1958, Doris became ill from nervous exhaustion, blaming it on overwork from making films which Marty insisted she make although she didn't want to. When Marty died in 1968, Doris was bankrupt. She was eventually awarded $22 million from Marty's estate by the courts.

From 1968 to 1973, Doris starred in her own TV series, The Doris Day Show. In 1975 she made a TV special: Doris Day Today and in 1985, she hosted a chat show, Doris Day's Best Friends, on cable TV.
