Liz Koch
Charles Koch got very lucky when Liz agreed to marry him. The Koch Industries owner picked the right woman to walk alongside him as he grew his company, as she is one of the most private people who rarely gives interviews and likes to keep to herself. This likely translates into relatively quiet home life for someone who must have had a lot on his plate during the course of a working day. Almost fifty years later, the pair is worth over $50 billion, and living a great final chapter of their lives.
Hélène Mercier
Although marrying French tycoon Bernard Arnault in 1991, Hélène Mercier hasn’t let his nearly $100 billion worth deter her from pursuing her passions. Although very supportive of her spouse, she has had a successful career of her own as a concert pianist. She was even honored with a prize as someone who has contributed to French culture and the influence the arts has on young people all over the country. We’re happy that she found her calling, rather than just becoming the stereotypical philanthropic wife.
