Doris was launched straight into stardom at age 17 when she began her career as a big band singer with Les Brown & His Band of Renown in 1939.
But she found her greatest success in slick, stylish sex comedies, beginning with 1959's Oscar-nominated "Pillow Talk", in which she and Hudson played two New Yorkers who shared a telephone party line.
Doris's mother, Alma, arranged for her to have lessons with singing teacher Grace Raine, who was so impressed that she gave her three sessions a week for the price of one.
Fellow actress Goldie Hawn said "Doris Day left us and took a piece of the sun with her" in an emotional Twitter message.
Day's signature song was "Que Sera Sera", a attractive tune made even better with her voice.More news: Samsung Insider: Galaxy Note 10 Won't Actually Get the Camera Upgrade
Her fear also led her to turn down an honorary Academy Award and Kennedy Center Honors Award because she could not fly out to receive them.
In addition to her recordings and her radio, TV and film work, Day was known later in life for her activism with animals.
The Man Who Knew Too Much: Scoring 91 percent on Rotten Tomatoes, this Hitchcock film is actually a remake of his original film made in 1939. "She had a heart of gold and was a very amusing lady who I shared many laughs with".
Her most famous songs, meanwhile, surely include the 1956 release of Que Sera, Sera (Whatever Will Be, Will Be).
She received the Presidential Medal of Freedom in 2004, and the Grammys gifted her a Lifetime Achievement prize in 2008. She changed her surname at the suggestion of a band leader who heard her sing "Day by Day".
She was married four times: first, to trombonist Al Jorden in 1941.More news: Leonard sinks buzzer, sends Raptors to East Finals
According to IMDB, Day's marriage to George Weidler was similarly short-lived.
Melcher committed Day to her television series, The Doris Day Show, without her knowledge.
Doris Day outlived her only child, record producer Terry Melcher, who died of melanoma in 2004 at the age of 62.
Doris Day mostly stayed out of the spotlight after leaving all the glitz and glamour of Hollywood behind.
Day married a fourth time at age 52, to businessman Barry Comden in 1976.
Melcher famously worked with The Beach Boys and turned down aspiring musician Charles Manson.More news: Apple Just Released The New Apple TV App
