The company has survived multiple market booms and busts since its predecessor’s founding in 1899 — from the Great Depression to the housing and financial crisis that precipitated the most recent recession. Multiple acquisitions and mergers over time led the one-man George Mackubin & Co., opened on Redwood Street downtown, to the modern-day company, which adopted the name Legg Mason in 1970. Since then it’s grown and even had a star mutual fund manager, Bill Miller, who handily beat the S&P 500 for 15 consecutive years before fading and leaving the firm in 2016.
