Continuing this week’s dedicated blog posts leading up to the series finale of ‘The Big Bang Theory’ this Thursday night on CBS, it’s time to learn about the man behind the outcast science nerds.

Chuck Lorre, TV’s 66-year-old mega-producer of popular sitcoms half-hour comedies, including ‘The Big Bang Theory,’ did not have a traditional route to his current position. In actuality, his long and winding path to the executive producer, show creator and showrunner that everyone wants today pivoted on the spur of the moment with a succinct determination that translated into one of the best elevator pitches.

It was an elevator pitch that, unlike a broken elevator in a certain Pasadena apartment complex, worked to help him move on up to the successful side of life.

Kaley Cuoco, Jim Parsons, Johnny Galecki, Simon Helberg, Kunal Nayyar, Melissa Rauch, and Mayim Bialik will be missed as a cast. Together, they delivered in so many ways — comedically as well as with those rare sweet moments like the napkin signed by Leonard Nimoy — that made them and ‘The Big Bang Theory’ must-see TV for 12 years. But we must also give credit to the men and women behind the scenes and cameras on set for creating the fictional world within Pasadena’s science community that millions of people around the world relate to and enjoy.

Chuck Lorre is one of these people.

And his personal story from a struggling musician to a prime time storyteller is not theoretical. It evolved his way, according to the script he was unknowingly writing for himself more than three decades ago.
