Passage: In 1962, Buffett became a millionaire because of his partnerships, which in January 1962 had an excess of $7,178,500, of which over $1,025,000 belonged to Buffett. He merged these partnerships into one. Buffett invested in and eventually took control of a textile manufacturing firm, Berkshire Hathaway. He began buying shares in Berkshire from Seabury Stanton, the owner, whom he later fired. Buffett's partnerships began purchasing shares at $7.60 per share. In 1965, when Buffett's partnerships began purchasing Berkshire aggressively, they paid $14.86 per share while the company had working capital of $19 per share. This did not include the value of fixed assets (factory and equipment). Buffett took control of Berkshire Hathaway at a board meeting and named a new president, Ken Chace, to run the company. In 1966, Buffett closed the partnership to new money. He later claimed that the textile business had been his worst trade. He then moved the business into the insurance sector, and, in 1985, the last of the mills that had been the core business of Berkshire Hathaway was sold. Buffett wrote in his letter: "... unless it appears that circumstances have changed (under some conditions added capital would improve results) or unless new partners can bring some asset to the partnership other than simply capital, I intend to admit no additional partners to BPL."In a second letter, Buffett announced his first investment in a private business — Hochschild, Kohn and Co, a privately owned Baltimore department store. In 1967, Berkshire paid out its first and only dividend of 10 cents. In 1969, following his most successful year, Buffett liquidated the partnership and transferred their assets to his partners. Among the assets paid out were shares of Berkshire Hathaway. In 1970, Buffett began writing his now-famous annual letters to shareholders. However, he lived solely on his salary of $50,000 per year and his outside investment income. In 1979, Berkshire began the year trading at $775 per share, and ended at $1,310....
