Susan Wojcicki, a Silicon Valley visionary who helped shape Google and YouTube, died Friday after a two-year battle with non-small cell lung cancer, according to her husband. She was 56.
“Susan was not just my best friend and partner in life, but a brilliant mind, a loving mother, and a dear friend to many,” her husband, Dennis Troper, wrote in a Facebook post. “Her impact on our family and the world was immeasurable.”
Wojcicki, born in Santa Clara, Calif., grew up on Stanford University’s campus, where her father was a physicist. There, she developed a passion for innovation and making a difference in the world. (Her two younger sisters, Anne and Janet, also went on to become powerhouses in their own respective fields.)
In 1998, Wojcicki rented her garage to Larry Page and Sergey Brin, a pair of Stanford grad students on the cusp of building the search giant Google.
Wojcicki quickly saw the company’s potential and left her job at Intel to become Google’s first marketing manager. In the years to follow, she quickly moved up the ranks, having a hand at growing the platform’s consumer products and building its advertising business.
