W. R. Berkley Corp

A global commercial-lines insurer that writes specialty coverage through roughly 60 decentralized, niche-focused businesses, from excess-and-surplus lines and environmental insurance to reinsurance and accident-and-health policies. It began in 1967 when Harvard Business School student William R. Berkley and a classmate started an investment firm called Berkley Dean & Company out of a campus apartment, later steering it into insurance. The company is named for its founder, who began investing his lawn-mowing earnings in the stock market at age twelve.
