Pearlman is best known for his hand in creating some of the biggest bands of the '90s, reported Variety.
In Florida in 1993, the producer brought together then-unknown singers AJ McLean, Nick Carter, Kevin Richardson, Howie D and Brian Littrell to create the Backstreet Boys. The band would go on to sell more than 130 million records.
In 1995, Pearlman also created NSYNC. Along with making massive sales, NSYNC can also be credited with jumpstarting Justin Timberlake's road to stardom.
He admitted to defrauding thousands of people and about ten banks in a Orlando, Florida, court in 2008.

As Judge G. Kendall Sharp read through a 47-page plea deal, drawn up by prosecution and defense lawyers to avoid a lengthy trial, Pearlman agreed to the charges. He was sentenced to 25 years two months later.
Included in the victims of Pearlman's scam were his friends, family and retirees, Sharp said, and he agreed to reduce Pearlman's sentence by one month for every USD 1 million returned.
NSYNC star Lance Bass meanwhile, posted, "Word is that #LouPearlman has passed away. He might not have been a stand up businessman, but I wouldn't be doing what I love today without his influence. RIP Lou."
Fellow NSYNC member Chris Kirkpatrick, Backstreet Boys' member AJ McLean, Aaron Carter and former O-Town member Ashley Angel Parker also pay tribute to Lou on Twitter.
"Many emotions at the news of Lou's passing. Without Lou I wouldn't have met my four brothers or had the opportunity of a lifetime. RIP," McLean said.
Carter shared, "#LouPearlman my old manager died in prison... Rip Lou not the best business guy really at all but he did discover me karma is real."
Ashley, meanwhile, posted a throwback photo of Lou and O-Town along with caption, "Love him or hate him, Lou gave many of us our start. It's a shame he let greed get in his way. #RIP #LouPearlman.
