In a career move away from academia, Von Clemm followed his father and grandfather to
Citibank in 1963 where he gained a reputation for innovation – and
dealmaking. He was responsible for inventing several financial instruments and services. Von Clemm was posted to London where he worked with a fellow American,
Stanislas Yassukovich, at
White Weld, on the development of the
Eurodollar Certificate of Deposit market. Citibank launched its first Eurodollar issues in 1966. In 1971, Yassukovich hired Von Clemm to join White Weld, first as a temporary consultant on the feasibility of a Euro-commercial paper market, which did not catch on. However, in 1972 Von Clemm effectively gave up his academic career to concentrate full-time on banking. He had an aggressive style – for example on one occasion printing up T-shirts for staff which read
Buy Bonds. He was also said to effectively bully clients into taking on the bank. When Credit Suisse took a 40% stake in White Weld, Von Clemm rose rapidly to become a senior Director of the Credit Suisse White Weld joint venture. However, Merrill Lynch made a bid to acquire White Weld in 1978 and
Credit Suisse needed a new partner. The existing Chairman
Sir John Craven wanted Dillon Read (later
Warburg Dillon Read). Von Clemm went behind his back and did a direct deal with First Boston, prompting Craven's resignation. Von Clemm replaced Craven as chairman of the newly formed
Credit Suisse First Boston, and then additionally chief executive in 1979. Although often controversial in his decisions, and taking several large risks, he turned CSFB from a relatively staid bank to a global powerhouse, propelling it into the top leagues of global banking. He stepped away from his chief executive role in 1983 but remained chairman until resigning in January 1986. Von Clemm was known for his enormous expense claims and dramatic personal style. He was a regular – practically weekly – user of
Concorde – and counted some of the world's most powerful figures as his friends. However, he also made large profits for his bank and was regarded as one of the biggest rain-makers in the
City of London. ==Roux Brothers==
