Detailed Analysis of DONALDSON COMPANY INC

About Warren Buffett: Warren Buffett is considered by many to be the greatest investor of all time. As the chairman of Berkshire Hathaway, Buffett has consistently outperformed the S&P 500 for decades, and in the process has become one of the world's richest men. (Forbes puts his net worth at $37 billion.) Despite his fortune, Buffett is known for living a modest lifestyle, by billionaire standards. His primary residence remains the gray stucco Nebraska home he purchased for $31,500 nearly 50 years ago, according to Forbes, and his folksy Midwestern manner and penchant for simple pleasures -- a cherry Coke, a good burger, and a good book are all near the top of the list -- have been well-documented.
