Duffield's admirers have never doubted that New Star would succeed. An Oxford graduate, Duffield, now 62, spent several years at a brokerage in the City of London and as a tax exile in Switzerland managing his wife's inheritance before founding Jupiter Asset Management in 1985. The company was so successful that Commerzbank (CRZBY
) paid $260 million for a 75% stake in 1995. Duffield left in 2000 after quarreling with the Germans over the terms of a buyout. Now, Jupiter is floundering--and Duffield is having his revenge.
