When Chenery returned from Europe in 1946, her father was concerned that she had no employable skills, so he offered to pay her the equivalent of the highest job offer she could get if she would go to graduate school instead. Chenery decided to attend Columbia Business School where she was one of 20 women in a class of 800 men. At Columbia, she met John (Jack) Bayard Tweedy. At her parents' suggestion, she dropped out of school a few months short of her MBA to marry Jack. They moved to Denver, Colorado, where he practiced oil and gas law. They had four children: Sarah, Kate, Christopher, and John Jr.. The Tweedys spent much of their time in Vail, Colorado. because Jack Tweedy was one of the former members of the 10th Mountain Division in World War II who founded Vail Ski Resort in the early 1960s. He was later Chairman of the Board of Vail Associates.
