Dabbs Greer - the most famous actor you didn't know

He appeared in more than 200 TV shows.

If you're lucky enough as an actor, you'll eventually land the role of a lifetime. Lucille Ball broke through with her hit sitcom I Love Lucy, while Andy Griffith received widespread recognition for his eponymous show.

But if an actor struggles to break through, they might face the music and move on to a different career.

However, there are certain actors out there who don't need the fame and fortune. Dabbs Greer was one of them.

This Sunday, the character actor would have been 100 years old. It's about time we honor him by looking back on his life and career as the most famous actor we never knew.

There's no doubt you've seen Greer on some of your favorite shows. Over the course of his 60-year career in Hollywood, Greer appeared as a guest star on literally hundreds of television shows. His first appearance was in 1951, on the science fiction program Space Patrol. 

In the 1950s, Greer appeared on smaller shows like Official Detective, The Web and Code 3. 

However, the 1960s brought more prominent roles. Greer is perhaps best known as the storekeeper Mr. Jonas on the long-running Western Gunsmoke. At the same time, he appeared on The Loretta Young Show, The Many Loves of Dobie Gillis, The Rifleman, The Andy Griffith Show and Rawhide

He was the minister who married Mike and Carol on the premiere of The Brady Bunch in 1969.

Greer's television work continued through the 1970s, when he finally landed the major role of Reverend Richard Alden on Little House on the Prairie in 1974. When that series ended in 1984, Greer became a character actor again and continued to make appearances up until 2003.

His last credited role was on the Disney channel TV show Lizzy McGuire. 

Greer passed away in 2007 at the age of 90. 

While TV legends like Desi Arnaz and Raymond Burr celebrate their centennials this year, it's important to remember those who also contributed to the medium but didn't receive the fame.
