Jonathan Egol, a Goldman Sachs managing director who worked with Fabrice Tourre when the bank created an ill-fated mortgage investment in the waning days of the housing boom, has left the firm.

Egol worked at the New York-based investment bank for more than 15 years and led a small team that assembled and traded derivatives tied to mortgages and other so-called "structured products." He left Goldman earlier this year, and the business he oversaw is being wound down, according to a person familiar with the matter. Egol's LinkedIn profile says he has "retired" from Goldman.
