A pert, vivacious and absolutely stunning brunette, the former Kathryn Grant (nee Olive Kathryn Grandstaff) is now known publicly as Kathryn Crosby. She was born in Houston, Texas in 1933 and appeared on stage from age 3. A graduate of the University of Texas and a student nurse at one point, she found her way into films via the beauty pageant circuit. She soon rose through the standard starlet ranks from unbilled parts to chipper "sis" types and decorative love interests alongside filmdom's top male stars.

She appeared opposite Richard Kiley in The Phenix City Story (1955), Tony Curtis in Mister Cory (1957), Jack Lemmon in Operation Mad Ball (1957), James Stewart in Anatomy of a Murder (1959) and Victor Mature in The Big Circus (1959), among others. Her best known role, however, was as the princess-in-distress in the special effects-laden epic fantasy The 7th Voyage of Sinbad (1958), which has since reached semi-cult status. For the most part, she felt unchallenged as an actress and retired rather uneventfully after marrying Bing Crosby in 1957. They had three children, including actress Mary Crosby of Dallas (1978) fame. Seemingly content with family life, she, along with her children, dutifully appeared opposite her husband singing and lightly joking in his many popular Christmas-special presentations and even hosted a couple of syndicated TV series, but that was about it.

After Bing's death in 1977, however, she slowly involved herself in acting again, appearing every now and then on stage in such productions as "Same Time, Next Year", "Charley's Aunt" and a Broadway revival of the musical "State Fair" in 1996. In addition to publishing two sets of memoirs ("Bing and Other Things" and "My Life with Bing"), she annually hosts the Crosby Gold Tournament in Winston-Salem, North Carolina.
