Warren Buffett has been married twice. Buffett married his first wife, Susan, in 1952. They had three children and were married for over 50 years, until Susan's death in 2004.

Although Warren and Susan had a long-lasting marriage, they were not together for all of it. They separated halfway through the marriage, in 1977, with Susan moving to San Francisco. Nevertheless, the two remained close, frequently talking on the phone even though they were apart.

Buffett's first wife had something to do with the business leader's next partner. Before her death, Susan introduced Warren to a waitress named Astrid Menks. Susan had asked Menks to check up on Warren while she was away. It was Menks who would later end up being Warren's companion and future wife. By 1978, Buffett and Menks were living together, and Christmas cards from the Buffett family were being sent out signed, "Warren, Susie and Astrid."

In 2006 Warren Buffett and Menks officially got married. The Berkshire Hathaway CEO held a low-key ceremony at his daughter Susie Buffett's home in Omaha, Nebraska. No business leaders were present, and neither were Buffett's two sons.

Although some may question the love triangle, friends remarked that the relationship among the three was sophisticated, and Susan was quoted with only good things to say about Menks.

"She takes great care of him, and he appreciates it and I appreciate it. She’s a wonderful person," Buffett's first wife said in an interview with Charlie Rose. According to Warren, "Susie put me together, and Astrid keeps me together."
