Financier and rogue. Born Barnett Isaacs in 1852, he made his first fortune in diamonds in South Africa and returned to England to become king of the market in gold shares ('kaffirs'). His visiting card bore the inscription 'I'll stand you a drink but I won't lend you a fiver'. Took to drink and commited suicide throwing himself overboard ship en route to England, south of Madeira. His funeral was attended by all the leading city figures. One of them later wrote: 'Poor Barney; what a tragic end for a gigantic humbug, but an amusing one.'
