Beginning her acting career in her early childhood, Trachtenberg gained recognition through her performances in well-known films and TV series, including “Harriet the Spy,” “Buffy the Vampire Slayer,” and “Gossip Girl.” Her passing has elicited a flood of tributes from colleagues and friends in the world of entertainment.
The New York Chief Medical Examiner’s Office ruled her death as “undetermined” and the family refused an autopsy. Sources close to Trachtenberg suggest that she may have succumbed to complications from a recent liver transplant, as per ABC affiliate KFSN. Criminal activity is not suspected by authorities.
Forensic vehicles and a government van were observed outside Trachtenberg’s high-end Manhattan apartment building near Central Park on Wednesday. Trachtenberg was last publicly seen the previous Thursday, dining with friends at Sartiano’s, an Italian eatery in New York City.
In the days leading up to her death, Trachtenberg was active on social media, posting selfies and nostalgic photos which caused concern among her fans. Her final post included a selfie with the caption “the warmth before the storm,” which elicited anxious comments from followers about her appearance and general health.
A representative of Trachtenberg confirmed her death but did not provide further details regarding the circumstances.
Trachtenberg was born in New York City in 1985. In a 2005 interview with Radio Free, she stated that her father Michael had migrated from Germany, while her mother Lana was from Russia. She split her childhood between New York and Los Angeles, California, living with her mother and sister Irene in Tarzana, a suburb of Los Angeles, while her father resided in Brooklyn, New York.
At the age of three, Trachtenberg started her career, first appearing on Nickelodeon before securing roles that would shape her career. She played Nona Mecklenberg in “The Adventures of Pete & Pete” before landing the title role in the 1996 film “Harriet the Spy.” Her significant breakthrough came when she was cast as Dawn Summers, the younger sibling of Sarah Michelle Gellar’s character, in “Buffy the Vampire Slayer.”
Later, Trachtenberg gained recognition for her portrayal of the scheming socialite Georgina Sparks on “Gossip Girl” from 2008 to 2012, a role she reprised in the show’s reboot in 2022-2023. Over her career, which spanned more than 62 movies and TV shows, she also featured in films such as “EuroTrip,” “Ice Princess,” and “17 Again.”
Trachtenberg’s sudden passing has stirred expressions of grief from friends and former co-stars.

Trachtenberg had an early love for acting, and as a child, “my mom would have to beg me to go on playdates because I would want to go on auditions.”
In that same interview, Trachtenberg spoke of her ongoing passion for her craft. “I love what I do. As long as I have that feeling, then I’m gonna stick to it,” she stated. “As long as I’m lucky enough to get projects and keep working, I will always be grateful for it.”
Trachtenberg received several award nominations for her performances throughout her career, including Teen Choice Award nominations for both “Buffy the Vampire Slayer” and “Gossip Girl.” She was also nominated for a Young Artist Award and a Saturn Award for her work on “Buffy.”
