Mark Zuckerberg and Priscilla Chan

Combined net worth: $74.2 billion

The founder and CEO of Facebook has often been characterized as a wunderkind, earning his first billion at just 23 years old, and his college-sweetheart wife, Priscilla Chan, has been by his side since the start.

Zuckerberg and Chan married in 2012 and are now parents to two daughters. In addition to the tech mogul's widespread revolutionizing of communication through social media, the couple is using their power to research and improve global health, education, and community through the Chan Zuckerberg Initiative.
