Naroditsky grew up in Foster City in San Mateo County. At 6, he began playing chess with his father, Vladimir, and brother, Alan, according to the San Mateo Daily Journal.
“To the world, Daniel is the chess grandmaster, passionate commentator and the gifted educator who we know and love. To me, he is all of those things — but he will always be Danya, my little brother,” Alan told KQED in a statement. He said the two loved watching Warriors games together, calling each other to discuss NBA highlights and swapping puns and inside jokes.
“He was my best friend, and one of the best human beings I have ever known,” he continued. “His death is a huge loss to us all.”
As a child, he won tournaments across the world, from his first locally in Burlingame to the under-12 world championship in Turkey.
“Chess is its own world,” Naroditsky told the San Mateo Daily Journal in 2007. “I enjoy being in it and staying in it; the tactics and strategies.”
He attended Crystal Springs Uplands School, a private middle and high school in Hillsborough.
“During his years at Crystal, Daniel was known not only for his extraordinary intellect and chess mastery, but also for his warmth, humility, and kindness,” Head of School Kelly Sortino said in a statement.
Through the years, the school has shared updates on Naroditsky’s burgeoning career, and he played against a chess computer there in an educational event organized by other alumni after his graduation.
