Goldman Sachs Group Inc. named Elisha Wiesel, son of Holocaust survivor Elie Wiesel, chief information officer as the company fills roles created by the departure of President Gary Cohn for a job in the Trump administration. Wiesel, 44, currently chief risk officer of the securities division, will report to Martin Chavez, who was promoted from CIO to chief financial officer last month, the New York-based firm said Monday in a memo to staff.
