Bonnie Bartlett

Bonnie Bartlett Daniels (born June 20, 1929) is a retired American actress, best known for her television roles, with her career spanning some seven decades, her first major role being on the 1950s daytime drama, Love of Life. Bartlett is known for her role as Grace Snider Edwards on the Michael Landon television series Little House on the Prairie and as Ellen Craig on the medical drama series St. Elsewhere. Her husband, actor William Daniels, played her fictional husband Dr. Mark Craig, and they both won Emmy Awards on the same night in 1986—becoming the first married couple to accomplish the feat since Alfred Lunt and Lynn Fontanne in 1965.

In 2026, having been married to her husband since 1951, hence a tenure of 74 years, they have the distinction of currently being the oldest living married couple in Hollywood.
