While a student at Juilliard, Uggams was tapped to join the cast of Sing Along with Mitch, becoming the first female singer and the first African-American talent to join the Mitch Miller-hosted variety program; in 1962, she also made her on-screen film debut with a cameo in Two Weeks in Another Town, and after signing to Columbia scored a hit single with "Morgan." She spent the next several years alternating nightclub dates with stage performances, also appearing in the theatrical production The Boyfriend. In 1968, Uggams was chosen to replace Lena Horne in the lead role in the Broadway musical Hallelujah, Baby!; the performance earned her a Tony Award and culminated her rise to stardom. In 1970, she was named the host of her own CBS variety series, the first black female since Hazel Scott a decade earlier to be given such an opportunity; however, The Leslie Uggams Show proved short-lived, one in a long list of sacrifices to the ratings juggernaut known as Bonanza.
The early '70s marked a decline in Uggams' fortunes; outside of an appearance in the all-star 1972 film Skyjacked, she enjoyed little of the same success of recent years, and a move from Columbia to Atlantic did little to resuscitate her singing career. In 1977, however, she returned to television in the slavery saga Roots, with her superb performance as Kizzy earning an Emmy nomination; two years later, Uggams earned more kudos for her work in another miniseries, Backstairs at the White House, and in 1983 won an Emmy as co-host of the short-lived NBC series Fantasy. Later in the decade, Uggams returned to Broadway, starring in the musicals Blues in the Night and Jerry's Girls. In 1987, she toured with Peter Nero and Mel Tormé in The Great Gershwin Concert, and in 1988 starred in the Lincoln Center production of Anything Goes. After touring during the early '90s in Stringbean, a musical based on the career of Ethel Waters, in 1996 Uggams joined the cast of the hit daytime soap opera All My Children. ~ Jason Ankeny, Rovi
