Husband of Facebook's Sheryl Sandberg dies suddenly on holiday aged 47

David Goldberg, a popular Silicon Valley executive and husband of Facebook second-in-command and Lean In author Sheryl Sandberg, died suddenly at age 47.

Goldberg was CEO of online survey questionnaire provider SurveyMonkey. He died on Friday night, the company said in a statement on its website.

Family members also reported the death, via postings on Facebook. Neither the company nor family released a cause or other details about his death. Facebook founder and CEO Mark Zuckerberg told The New York Times that Goldberg died while he was on vacation abroad with his wife.

"Dave Goldberg was an amazing person, and I am glad I got to know him," Zuckerberg wrote on his Facebook page. "My thoughts and prayers are with Sheryl and her family."

In an interview last month, Goldberg told the news site Business Insider of maxing out his credit cards in the early 1990s to fund one of his first internet ventures, a music site, before going on to work at other tech companies, including Yahoo.

In 2004, Goldberg married Sandberg, another longtime tech executive who now serves as Facebook's chief operating officer. Sandberg launched an international conversation about the dearth of women in positions of power with her 2011 book Lean In: Women, Work and the Will to Lead.
