Doris Day (1922-2019) was an American singer, actress, and animal welfare advocate whose career spanned seven decades. Her warm, intimate vocal style and impeccable phrasing made her one of the best-selling recording artists of the 20th century, with particular success in jazz standards and popular song from the 1940s through 1960s.
Beyond her entertainment career, Day became known for her advocacy work, especially in animal protection. Her recordings remain essential references for musicians studying American popular song, vocal interpretation, and the Great American Songbook.
