The birthday boy for September 23 is Jason Alexander.
There was nothing about George Costanza to remind me that Jason Alexander was a Libra. His character on “Seinfeld” had to have something more manic about him, so I expected to find either a strong irrational Pisces influence in his chart or a stellium in neurotic Virgo, because there aren’t a lot of sitcom actors who can make a living playing characters so unlike themselves.
Looking at his natal chart, I didn’t find any planets in Virgo besides Pluto. However, I did discover that Alexander has a Pisces rising. He also has a Gemini moon which can explain a few more things about the mercurial George Costanza.
In person, Alexander seems calm and rather dignified — just like a Libra native. Yet he didn’t have to go very far within himself to access the parts of his chart that helped to make him a star.
