Rainer Gut, Who Built Credit Suisse Into Global Bank, Dies at 91

Rainer Gut, who engineered the mergers and acquisitions that transformed Switzerland’s Credit Suisse Group AG into a giant global investment bank, one that proved difficult for subsequent generations of executives to manage, has died. He was 91.

The Swiss-born Gut, whose career included stints on Wall Street, held top positions at Credit Suisse from 1971 to 2000, and was honorary chairman until April. His ambition, as he put it, was to expand the Zurich-based bank beyond its roots in private wealth management to become “a major player in every area of financing activity around the globe.”
