Frank V. Cahouet, the feisty retired chief executive credited with rescuing Pittsburgh’s iconic Mellon Bank from the brink of failure in the late 1980s, died June 2017. The Sewickley Heights resident, who had Parkinson’s disease, was 85. A Boston native, Mr. Cahouet worked some 25 years at major banks in California before arriving at Mellon Financial in 1987, the first CEO not to have risen from inside the bank’s ranks. He retired from Mellon at the end of 1998. The bank was acquired by New York City’s Bank of New York in 2007, forming BNY Mellon. Since his retirement, Mr. Cahouet remained active in the Pittsburgh community, serving on numerous boards, including the University of Pittsburgh, Carnegie Mellon University, Pittsburgh Regional Alliance, World Affairs Council of Pittsburgh, Historical Society of Western Pennsylvania, Teledyne Technologies and others. Mr. Cahouet, who was born May 25, 1932, is survived by his wife Ann and four children: Ann P. Cahouet, Frank Cahouet Jr., Mary Cahouet-Rotondi and David Cahouet, plus six grandchildren.
