Davis Roberts (born Robert A. Davis, March 7, 1917 – July 18, 1993) was an American character actor whose career spanned five decades, from the late 1940s until just before his death in 1993. He started out making films in the 1940s and 1950s and expanded into television work in the following decades. Davis was known for his dignified portrayals which were often in contrast to prevailing stereotypical roles. He played the role of Dr. Caldwell in three episodes in the second and third seasons of the NBC-TV sitcom series Sanford and Son, and as Dr. Ozaba in the 1968 episode "The Empath" in the original Star Trek series.
