Charles W. Duncan Jr., energy secretary during Carter-era oil crunch, dies at 96

Charles W. Duncan Jr., who directed U.S. energy policy under the Jimmy Carter administration amid oil-supply shocks from Iran’s Islamic revolution and OPEC threats as the White House struggled to avoid another panic of long lines at gas pumps, died Oct. 18 at his home in Houston. He was 96.

Mr. Duncan had a series of health complications following a fall earlier this month, said his son, Charles W. Duncan III.
