Daves brother posted the news on his Facebook page Saturday morning.
Facebook CEO Mark Zuckerberg shared this post on his own page shortly after.
Dave Goldberg was an amazing person and I am glad I got to know him.
My thoughts and prayers are with Sheryl and her family.
Dave was born on 2 October 1967 in Minnesota and majored from history and government at Harvard University.
Goldberg married Ms Sandberg who was then a Google executive, in 2004.
She had always praised his pro-equality stance for women in the work place.
