(Bloomberg) -- For almost three decades, Michael Larson has quietly shuffled around one of the world’s biggest fortunes with a chief priority: Keep his fabulously wealthy bosses out of the headlines. The conservative bets, the nondescript office, the investment firm’s generic-sounding name; they were all carefully designed to shield Bill Gates and Melinda French Gates from criticism and produce steady, if seemingly unimpressive, returns. The couple’s divorce announcement last month cracked the curated image. Unflattering details spilled out, including a report that Larson, the mastermind behind Cascade Investment, had allegedly harassed and bullied some employees.
