Cosmo Silverman, 15, Tragically Passes Away Following Accident at Campbell Hall

The community of Campbell Hall School and the broader Los Angeles area is reeling with grief after the sudden and heartbreaking loss of 15-year-old student Cosmo Silverman, who tragically passed away following a devastating accident on school grounds. Known for his vibrant spirit, boundless creativity, and warm heart, Cosmo’s death has left an immense void in the hearts of all who knew him.

The accident occurred earlier this week on the campus of Campbell Hall, a private Episcopal day school in Studio City. While full details have not been publicly disclosed out of respect for the family’s privacy, the incident was described as a sudden and tragic accident that claimed Cosmo’s young life far too soon. Emergency responders arrived swiftly, and every effort was made to save him, but the severity of the accident ultimately proved fatal.

Cosmo was a beloved sophomore who was deeply involved in both academic and extracurricular life at Campbell Hall. He was admired by peers and teachers alike for his inquisitive mind, kind demeanor, and an unwavering passion for learning. Whether he was engaging in spirited classroom discussions, participating in school theatre productions, or lending a helping hand to classmates, Cosmo brought a light that brightened every room he entered.

Teachers recall Cosmo as an exceptional student with a natural curiosity and a rare ability to connect with people across all walks of life. “He had an old soul,” one teacher noted. “He could talk about science, art, and life with a wisdom that far exceeded his years. And he did so with humility and kindness.”

Cosmo’s friends remember him as a fiercely loyal companion who made others feel seen and valued. He had a knack for turning the mundane into magic—transforming a normal school day into something memorable with his wit, humor, and imagination. His infectious laugh and thoughtful gestures will be etched into the memories of those lucky enough to have called him a friend.

Outside of school, Cosmo was an avid reader, aspiring filmmaker, and animal lover. He often spent weekends volunteering at local shelters or experimenting with storytelling through video and photography. He dreamed of one day making films that could change the world, offering new perspectives and sparking conversations about empathy, justice, and the beauty of everyday life.

Cosmo is survived by his loving parents, Rachel and David Silverman, and his younger sister, Zoe, who adored him deeply. The Silverman family has been a cherished part of the Campbell Hall community for years, and the loss of their son has sent shockwaves throughout the school and beyond. In a public statement, the family expressed profound gratitude for the outpouring of love and support:

“Cosmo was a beautiful soul, full of life, compassion, and dreams. We are heartbroken beyond words, but we take some comfort in knowing how deeply he touched the lives of others. Thank you for holding him—and us—in your hearts.”

In response to the tragedy, Campbell Hall has offered grief counseling and created a memorial space on campus where students, faculty, and friends can leave flowers, photos, letters, and tokens of remembrance. A candlelight vigil is planned for later this week to honor Cosmo’s memory, with the school community coming together to celebrate the impact he made in his short but meaningful life.

As the community mourns the loss of this extraordinary young person, one message echoes among the sorrow: Cosmo Silverman’s life, though brief, was a gift to all who knew him. His spirit will live on in the stories shared, the lives touched, and the enduring love he inspired.

Rest in peace, Cosmo. You were a star among us, and your light will never fade
