Jerry and Jessica Seinfeld Wish Their Son a Happy 20th Birthday: "Your Goodness Is Greatness"

Jerry Seinfeld may be a world-famous comedian — but to his kids, he's just Dad. Over the years, he's worked hard to be a good example for them. "We just try to build decent human beings. We're not trying to beat them over the head that they have to give back," he told The New York Times in 2012. "The only way to really do it, we believe, is by doing it yourself and modeling it and hopefully they follow."

Years later, it seems like his efforts have paid off. On March 1, Jerry's wife, Jessica Seinfeld, posted a photo of their son Julian on Instagram in celebration of his 20th birthday and praised him extensively in the caption for being a good person. "Happy 20th Birthday to @julianseinfeld!" she wrote. "Your work ethic enables you to balance a heavy college course load with a job you love. Your sharply tuned BS detector suffers not one fool. The moral high bar you set for those around you keeps us all in line. You chose your friends wisely, and treat them all like family. You are such a phenomenal and gorgeous human being. Your goodness is greatness, especially in this world today. I love you, my sun 🌞."

In the comments, Jerry popped in to show some love as well. "We love you so much, Jules," he wrote. "Happy Special Birthday this year!!❤️❤️❤️❤️❤️."

Jerry and Jessica tied the knot in 1999, and their oldest child, Sascha, was born a year later. Read on to learn more about the Seinfeld kids.

Sascha Seinfeld

The couple's eldest daughter, Sascha, was born on November 7, 2000. She started school at Duke University in 2019, but seems to have remained close to her parents over the years.

In 2021, her mom celebrated her 21st birthday with an affectionate Instagram post. "We had the best weekend celebrating this phenomenal human being, along with her friends, who love her almost as much as we do," she wrote. "She works hard, she plays hard, and in between, makes life better for everyone in her orbit. 🧚 I love you, Little Magic Girl. ❤️✨💫🌟🌠 I am so proud to be your mom."

Julian Kal Seinfeld

Julian was born March 1, 2003. He followed in his sister's footsteps and started attending Duke University in 2021. Judging by his LinkedIn, he's currently interning at sports media company Thirty Five Ventures.

In an interview with Parents, Jessica admitted that Jerry didn't take to being a dad immediately. "The nicest way to say this is that he wasn't a natural when our kids were born," she said in the 2020 feature. "He wasn't immediately pushing strollers and carrying babies. He jokes that it took him a good 10 years to warm up."

Shepherd Kellen Seinfeld

The couple's youngest child, Shepherd, was born on Aug. 22, 2005. The 17-year-old currently has no social media and there's not much information about him online in general, but his dad occasionally comments on family life. In 2017, he told Mr. Porter that he enjoys everything about parenthood, especially the "garbage time," or the less fun parts of being a dad. "That's what I like. You just see them in their room reading a comic book and you get to kind of watch that for a minute, or [having] a bowl of Cheerios at 11 o'clock at night when they're not even supposed to be up," he said. "The garbage, that's what I love."
