Timothy H. Ling, president and chief operating officer of Unocal Corp., died suddenly of apparent natural causes on January 28 after an ice hockey workout in El Segundo. He was 46. “Tim Ling was a brilliant executive with boundless energy and enthusiasm,” said Charles R. Williamson, Unocal’s chairman and chief executive officer. “He lived every moment with gusto. Although his life was tragically short, it was remarkably full. The entire Unocal family is shocked and saddened by Tim’s sudden passing. We will miss him terribly.” Williamson indicated that he would assume Ling’s responsibilities as president and chief operating officer on an interim basis, effective immediately. Ling was also a member of the company’s management committee and had served as a member of Unocal’s board of directors since 2000. Previously, he was executive vice president, North American Operations. He joined Unocal in 1997 as chief financial officer. “Tim invested every ounce of his extraordinary energy in making Unocal successful,” Williamson said. “His leadership and commitment were unwavering. He embraced change and challenge like no one else I have ever worked with.” Williamson noted that, with the help of Ling’s leadership, Unocal has made a lot of difficult changes over the past few years, strengthening its profitability and future growth potential. Ling was instrumental in developing and leading many of Unocal’s key business initiatives. He also helped to assemble a multitalented, highly experienced management team. “Thanks in good part to Tim’s vision and commitment, Unocal is traveling a clear and well- marked path to future success,” Williamson added. “We owe him a legacy of continued achievement and improved performance.” Born in Philadelphia, Ling earned a degree in geology from Cornell University in 1982 and an MBA at Stanford in 1989. Prior to joining Unocal, he was a partner at McKinsey & Company in Los Angeles. He also worked as a research geologist for the United States Geological Survey at Woods Hole, Massachusetts, where his focus was on the assessment of deepwater energy and mineral resources. In 1987, Ling married Kimberly De Mello. He was a devoted family man and actively involved in his young children’s lives, including coaching his eldest son’s ice hockey team. He was also an accomplished vocalist and musician who played both the cello and the piano. Ling was a director of the American Petroleum Institute, the Domestic Petroleum Council and Maxis Communications, a cellular telephone provider in Malaysia. He also served on an advisory board for the Department of Energy and was on the management board for the Stanford University Graduate School of Business. Meanwhile, he served as an officer and board member of the Los Angeles Philharmonic Association, where he helped raise funds to complete Walt Disney Concert Hall. In addition to his wife, Ling is survived by their three children, Hudson, 7, Tommy, 4, and Peter, 2; his parents, Gilbert and Shirley Ling of Marion, PA; his sister and her husband, Eva and Neil Monahan of Wynnewood, PA, and their children, Stephanie and Casey; and his brother and his wife, Dr. Mark and Jenny Ling of Atlanta, GA, and their children, Sydney and Graham. Funeral arrangements are pending. In lieu of flowers, the family requests that donations be made to either the Tim Ling Memorial Fund at St. Matthew’s Parish Church in Pacific Palisades or to the Tim Ling Scholarship Fund, in care of the Los Angeles Philharmonic Association.
