Lucille Ball would have turned 100 on Saturday, Aug. 6. To celebrate her legacy, LIFE magazine at has posted a gallery of never-before-published photographs of the comedienne.

In this 1958 photo by Leonard McCombe for TIME & LIFE Pictures, we see Desi Arnaz and Lucille Ball posing in front of their then-latest venture, Desilu Studios. Fun fact: When Lucy and Desi launched I Love Lucy, they started a TV revolution not only by shooting their sitcom in Hollywood, but also by being the first to use a three-camera set. Yes. You can credit and later blame or still credit Lucy and Desi for the multi-cam sitcom.
