Lou Pearlman, who has died at the age of 62, will be remembered for founding boy bands Backstreet Boys and NSYNC – and for a $300 million Ponzi scheme that led to him being jailed for up to 25 years. Pearlman was seen as an aggressive but initially successful manager who built up a business through talent-spotting, tough negotiation and a string of half truths. The empire later collapsed with its acts suing their manager.
