Kathryn Crosby (November 25, 1933 - September 20, 2024) was an American actress and singer who also performed under the stage-name Kathryn Grant. Born Olive Kathryn Grandstaff in Houston, Texas, she graduated from the University of Texas at Austin with a Bachelor of Fine Arts in 1955. Two years later she became Bing Crosby's second wife. The couple had three children, Harry, Mary Frances, and Nathaniel. She appeared as a guest star on her husband's 1964–1965 ABC sitcom The Bing Crosby Show. She largely retired after their marriage, but did have a featured role in the courtroom drama Anatomy of a Murder. She also played the part of "Mama Bear" alongside her husband and children in Goldilocks and starred with Jack Lemmon in Operation Mad Ball in 1957. In the mid-1970s, she hosted The Kathryn Crosby Show, a 30-minute local talk-show on KPIX-TV in San Francisco. Husband Bing appeared as a guest occasionally. After Bing Crosby's death in 1977, she took on a few smaller roles and the lead in the short-lived 1996 Broadway musical State Fair. For 16 years ending in 2001, Crosby hosted the Crosby National Golf Tournament at Bermuda Run Country Club in Bermuda Run, North Carolina. A nearby bridge carrying U.S. Route 158 over the Yadkin River is named for Crosby. On November 4, 2010, Crosby was seriously injured in an automobile accident in the Sierra Nevada that killed her 85-year-old husband, Maurice William Sullivan.
