  • Bill Gates, the founder of Microsoft, married Melinda French in 1994.
  • They met at Microsoft when Melinda was brought on a product manager. She initially turned down Bill’s request for a date at a company picnic.
  • Today, they run the Bill & Melinda Gates Foundation, which has an endowment of $40.3 billion.

Melinda French was less than impressed when her boss asked her out on a date.

It was 1987, and the recent Duke graduate had just joined Microsoft as a product manager. CEO Bill Gates approached her at a company picnic and asked if she’d be interested in grabbing dinner in two weeks. She responded, “That’s not spontaneous enough for me,” Fortune reported in 2015.

Fast-forward three decades, and Bill and Melinda Gates are married with three kids, worth $98.1 billion, and run a namesake philanthropic enterprise boasting a $50.7 billion endowment.

Here’s a look at their marriage.
