Leave it to Beaver fans got to know Beaver’s very first teacher, Miss Canfield, in the show’s very first episode, which debuted Oct. 4, 1957. Played by popular character actress Diane Brewster, Ms. Canfield appeared in only a handful of episodes throughout the show’s first season (including the show’s ill-fated pilot), but she earned spot in Leave it to Beaver fans’ hearts — so much so that Brewster would return in the role in the 1983 TV movie Still the Beaver and the sequel series The New Leave it to Beaver, which ran from 1983-1988. But while plenty of the actress’s fans may remember as Beaver’s beloved teacher, they might not know the surprising connection she had to TV’s The Fugitive — she played Helen Kimble, the woman murdered by the infamous One-Armed Man.
