Buffett, after several years, decided to wind up the partnership, returning the lucky investors their capital and their share of the profits, and bought an interest in Berkshire Hathaway, a textile company, giving his original investors the chance to invest. The smart ones did so. Buffett's early days at Berkshire Hathaway were not great. The company was in an industry facing real challenges from exports and high manufacturing costs. Warren Buffett had not, however, forgotten what he had learned under Graham, and arranged for the company to buy out two Nebraska insurance companies. This was the start of Buffett 's interest in insurance and the rise to financial fame of both himself and Berkshire Hathaway. The insurance game is a hard one but under Buffett, the company has become, not only a successful share investors, but also a leading provider of insurance.
