Who is Charlie Munger from Buffett: The Making of an American Capitalist and what is their importance?

Charlie Munger was a lawyer by profession but since the 1960's he had managed Wheeler, Munger and Company, an investment partnership in California. He and Buffett met quite by accident. Both had been purchasing stock in Blue Chip Stamps, a grocery store trading stamp company popular in those times. Buffett eventually became the largest stockholder, Munger the second largest. Buffett and Munger eventually met and formed a friendship and alliance which has stood the test of time. They have invested together and are of the same philosophical approach to the stock market and the value of companies. Most people see them as "clones" of one another.
