Contrarian investor Jonathan Ruffer told the FT in early 2006 that 'there was not an ounce of entrepreneurial spirit in me'. That did not stop him from setting up one of the City's most admired hedge fund operations. Cambridge-educated Ruffer worked as a stockbroker and a barrister before joining Dunbar, a private bank. He finally set up his own business in 1994. Ruffer Management saw its funds under management rise 13% to £15.4bn in 2012-13. Profits also hit a record £115.3m on £146m turnover. Ruffer, who with his family owns just more than half, is a Christian and philanthropist, best known for spending £11m to save County Durham's Auckland Castle and its religious paintings from being auctioned off.
