Warren Buffett married his second wife, Astrid Menks, in 2006.
The wedding took place on Buffett's 76th birthday, linking the marriage to a notable milestone in the investor's personal life. Menks had been Buffett's longtime companion and had lived with him for many years before they formally married.
Buffett's first wife, Susan Thompson Buffett, remained married to him but moved to San Francisco in 1977 to pursue a singing career. Before leaving Omaha, Susan introduced Warren to Astrid, and the three maintained a close relationship. For years, Christmas cards from the household were signed by Warren, Susan, and Astrid.
The 2006 marriage is sometimes misunderstood as beginning Buffett's relationship with Menks. In fact, they had already shared a household for decades. It also followed a major public philanthropic event: that same year, Buffett announced plans to donate the overwhelming majority of his fortune, largely through gifts to the Bill & Melinda Gates Foundation.
