Werner Kurt Rey (born October 6, 1943 in Zürich) is a Swiss entrepreneur former bank clerk, who made a name for himself in 1976 when acquiring the majority of the venerable but loss-making Bally Shoe company and selling his stake soon later with a profit of around 60 million Swiss francs.
Subsequently, his investor and venture capitalist career took off from that of an initiator of hostile take-overs to that of a USD billionaire white knight in various international M&A deals ranging from real estate to engineering works, electronics, media and financial services, in which he himself served occasionally as guarantor to institutional lenders.
