Former YouTube CEO and longtime Google executive Susan Wojcicki has died at age 56.

Susan Wojcicki, former YouTube CEO and longtime Google executive, has died, her husband said. She was 56.

“My beloved wife of 26 years and mother of our five children passed away today after two years of living with non-small cell lung cancer,” Dennis Troper said in a post on social media Friday evening.

“Susan was not only my best friend and life partner, but also a brilliant mind, a loving mother, and a close friend to many people,” said the Troper.

No other details about her death were released.

Wojcicki, who played a key role in the founding of Google, he went down as CEO of YouTube in 2023 after nine years at the helm of the video-sharing service that transformed entertainment, culture and politics.

Shortly after Google co-founders Larry Page and Sergey Brin turned their search engine into a business in 1998, Wojcicki rented a garage in her Menlo Park, California, home for $1,700 a month.

Wojcicki and Troper’s 19-year-old son, Marco Troper, he died in February on the campus of the University of California at Berkeley, where he lived as a freshman.
