Donna Reed was born Donnabelle Mullenger on January 27, 1921 in Denison, Iowa. Her first movie role was in 1941, when she appeared in The Getaway. She would act in two other films that year.
1942 was a busy year for Reed, since she appeared in seven movies that year including The Courtship of Andy Hardy. She is remembered for co-starring with James Stewart in It’s A Wonderful Life in 1947, which has become a Christmas classic.
Reed would also appear in From Here To Eternity in 1953. She won an Academy Award for Best Supporting Actress in the movie.
Her first television appearance was in an episode of Ford Television Theatre in 1954. Reed appeared in six more movies and made appearances in three television shows, before she took the role of Donna Stone in the Donna Reed Show.
After the show ran from 1958-1966 she wouldn’t appear on-screen again, till 1979 when she appeared in a TV movie, which was named The Best Place To Be. Reed was last seen as Ellie Ewing in Dallas, in 1984 and 1985 before her death in 1986.
Donna Reed died of pancreatic cancer on January 14, 1986 at the age of 64 in Beverly Hills, California.
Carl Betz
Carl Lawrence Betz was born on March 9, 1921 in Pittsburgh, Pennsylvania. Betz portrayed Collie Jordan on the Love of Life soap opera in 1951 in his first television role. Betz would appear in his first credited movie The President’s Lady in 1953.
He then appeared in five more movies in 1953, then wouldn’t appear in another movie till 1966, when he appeared with Elvis Presley in Spinout. He had barely finished his last episode of the Donna Reed Show, when he was in the cast of Judd For The Defense from 1967-1969. He appeared in 50 episodes of the series as Clinton Judd. Betz appeared mostly in various television series till the end of 1977.

Paul Petersen
Paul Petersen was born as William Paul Petersen on September 23, 1945, in Glendale, California. Petersen recorded a song She Can’t Find Her Keys during the time he was on the Donna Reed Show. Petersen made his first television appearance at the age of 11 on Walt Disney’s Wonderful World of Color in 1956 in the Along the Oregon Trail episode.
He would appear in all 275 episodes of the Donna Reed Show and was the only one besides Donna Reed to appear in all the episodes filmed. He appeared in 83 more episodes than Shelley Fabares, who played his sister Mary.
Peterson appeared in numerous television series, after the show ended its run in 1966.
He will be seen in The Executive which is currently filming and Kathy Garver, who portrayed Cissy on Family Affair will also be in the cast.
The role of Jeff Stone later would cause Petersen much anguish, because he wasn’t being taken seriously, when looking for more mature roles. He had been an original Mousketeer on the Mickey Mouse Club at the age of 8 in 1955.
Petersen would start an organization named A Minor Consideration, which was a child actor support group.
When he couldn’t find work as an actor Mickey Rooney talked him into attending college.
This quote from Petersen explains why he became a child actor:
“I became a child actor because my mom was bigger than I was.”
Petersen was not happy when actor Bill Bixby took his wife: [on losing wife Brenda Benet to Bill Bixby] I was so angry I couldn’t see straight, and what doubled this pain was that Bill was really visible. You know, he was going great guns and I was going in the toilet.
He has reached out to many former child stars, who needed emotional support from someone like him, who had been under the same stress as they were experiencing.
It is hard to believe that the teenage Jeff Stone will be 70 next year.
