Although everyone agrees that he is ridiculously young for one so senior, Jeremy Isaacs is already a veteran, having started his career in banking at the age of 17 as a clerk at Smith Brothers. In the 1980s he worked in the open-outcry pit of the London Traded Options Market, and put in a stint at Kleinwort Benson before joining Goldman Sachs in 1989.
By the time Lehman Brothers lured him away in 1996, he was an executive director in the equities department at Goldman Sachs. He became co-chief operating officer of European equities at Lehman. Later that year Lehman named him global head of equity derivatives as well. The next year, 1997, the firm named him overall head of its European equities businesses. He became chief operating officer for Europe in 1999, and later that year was named chief executive officer.
He is a famous risk manager and taker, and his track record in the equities businesses - which he turned around - has earned him some powerful fans within the firm. Colleagues describe him as astute, charismatic and straightforward: a manager in the Lehman Brothers mould.
In his spare time, Isaacs likes fast cars and yachts. When his chauffeur has the day off he occasionally turns up at work in an Aston Martin Vantage.
