Warren Buffett
Warren Edward Buffett is an American investor and philanthropist who is the chairman and former CEO of the conglomerate Berkshire Hathaway. As a result of his success, Buffett is one of the best-known investors in America. According to Forbes, as of January 2026, Buffett's estimated net worth stood at US$148.9 billion, making him the ninth-richest individual in the world.
Buffett was born in Omaha, Nebraska. The son of U.S. congressman and businessman Howard Buffett, he developed an interest in business and investing during his youth. He entered the Wharton School of the University of Pennsylvania in 1947 before graduating from the University of Nebraska in Lincoln at 20. He went on to graduate from Columbia Business School, where he molded his investment philosophy around the concept of value investing pioneered by Benjamin Graham. He attended New York Institute of Finance to focus on his economics background and soon pursued a business career.
He then began several business ventures and investment partnerships, including one with Graham. He created Buffett Partnership Ltd. in 1956 and his investment firm eventually acquired textile manufacturer Berkshire Hathaway, applying its name to a diversified holding company. Buffett emerged as the company's chairman and majority shareholder in 1970. In 1978, fellow investor and long-time business associate Charlie Munger joined Buffett as vice-chairman.
From 1970 to 2026, Buffett presided as the chairman and largest shareholder of Berkshire Hathaway, one of America's foremost holding companies and world's leading corporate conglomerates. He has been referred to as the "Oracle" or "Sage" of Omaha by global media as a result of having accumulated a massive fortune derived from his business and investment success. Buffett adheres to the principles of value investing and frugality despite his wealth. Buffett has pledged to give away 99 percent of his fortune to philanthropic causes, primarily via the Gates Foundation. He founded the Giving Pledge in 2010 with Bill Gates, whereby billionaires pledge to give away at least half of their fortunes. At Berkshire Hathaway's investor conference on May 3, 2025, Buffett requested that the board appoint Greg Abel to succeed him as the company's chief executive officer by the year's end, while remaining chairman.
Early life and education
Buffett was born on August 30, 1930, in Omaha, Nebraska, as the second of three children and the only son of Congressman Howard Buffett and his wife, Leila Buffett. He began his education at Rose Hill Elementary School. In 1942, his father was elected to the first of four terms in the United States Congress, and after moving with his family to Washington, D.C., Warren finished elementary school, attended Alice Deal Junior High School and graduated from what was then Woodrow Wilson High School in 1947, where his senior yearbook picture reads: "likes math; a future stockbroker". After finishing high school and finding success with his side entrepreneurial and investment ventures, Buffett wanted to skip college to go directly into business but was overruled by his father.Buffett showcased an interest in business and investing at a young age. He was inspired by a book he borrowed from the Omaha public library at age seven, One Thousand Ways to Make $1000. Much of Buffett's early childhood years were enlivened with entrepreneurial ventures. In one of his first business ventures, Buffett sold chewing gum, Coca-Cola, and weekly magazines door to door. He worked in his grandfather's grocery store. While still in high school, he made money delivering newspapers, selling golf balls and stamps, and detailing cars, among other means. On his first income tax return in 1944, Buffett took a $35 deduction for the use of his bicycle and watch on his paper route. In 1945, as a high school sophomore, Buffett and a friend spent $25 to purchase a used pinball machine, which they placed in the local barber shop. Within months, they owned several machines in three different barber shops across Omaha. In 1947 they sold the business to a war veteran for $1,200.
Buffett's interest in the stock market and investing dated back to his schoolboy days spent in the customers' lounge of a regional stock brokerage near his father's own brokerage office. His father took interest in cultivating and educating the young Warren's curiosity surrounding the subject of business and investing, even at one point taking him to visit the New York Stock Exchange when he was 10. At 11, he bought three shares of Cities Service Preferred for himself, and three for his sister Doris Buffett. At 15, Warren made more than $175 monthly delivering Washington Post newspapers. In high school, he invested in a business owned by his father and bought a 40-acre farm worked by a tenant farmer. He bought the land when he was 14 years old with $1,200 of his savings. By the time he graduated from college, Buffett had amassed $9,800 in savings.
In 1947, Buffett matriculated at the Wharton School of the University of Pennsylvania. He would have preferred to focus on his business ventures, but enrolled due to pressure from his father. Warren studied there for two years and joined the Alpha Sigma Phi fraternity. He then transferred to the University of Nebraska where he graduated with a Bachelor of Science in Business Administration with major in Investment Management in 1951. After being rejected by Harvard Business School in the spring of 1950, Buffett enrolled at Columbia Business School of Columbia University upon learning that Benjamin Graham taught there. He earned a Master of Science in Economics from Columbia in 1951. After graduating, Buffett attended the New York Institute of Finance.
Business career
Early business career
Buffett worked from 1951 to 1954 at his father's firm, Buffett-Falk & Co., as an investment salesman; from 1954 to 1956 at Graham-Newman Corp. as a securities analyst; from 1956 to 1969 at several investment partnerships as the general partner; and from 1970 as chairman and CEO of Berkshire Hathaway Inc.In 1951, Buffett discovered that Graham was on the board of GEICO insurance. Taking a train to Washington, D.C., on a Saturday, he knocked on the door of GEICO's headquarters until a janitor admitted him. There he met Lorimer Davidson, GEICO's vice president, and the two discussed the insurance business for hours, and Buffett made his first purchase of GEICO stock. Davidson would eventually become Buffett's lifelong friend and a lasting influence, and would later recall that he found Buffett to be an "extraordinary man" after only fifteen minutes. Buffett wanted to work on Wall Street but both his father and Ben Graham urged him not to. He offered to work for Graham for free, but Graham refused.
Buffett returned to Omaha and worked as a stockbroker while taking a Dale Carnegie public speaking course. Using what he learned, he felt confident enough to teach an "Investment Principles" night class at the University of Nebraska-Omaha. The average age of his students was more than twice his own. During this time he also purchased a Sinclair gas station as a side investment but it was unsuccessful.
In 1954, Buffett accepted a job at Benjamin Graham's partnership. His starting salary was $12,000 a year. There he worked closely with Walter Schloss. Graham was adamant that stock picks should provide a wide margin of safety after weighing the trade-off between their price and their intrinsic value. In 1956, Benjamin Graham retired and closed his partnership. At this time Buffett, who had amassed personal savings over $174,000, decided to return to Omaha, where he would quickly start a series of investment partnerships.
In 1957, Buffett operated three investment partnerships. By 1959, the total had grown to six partnerships. That summer, Buffett was introduced to his future partner Charlie Munger during a business luncheon at The Omaha Club. In 1961, Buffett revealed that 35% of the partnership's assets were invested in the Sanborn Map Company. He explained that Sanborn stock sold for only $45 per share in 1958, but the company's investment portfolio was worth $65 per share. This meant that Sanborn's map business was being valued at "minus $20". Buffett eventually purchased 23% of the company's outstanding shares as an activist investor, obtaining a seat for himself on the board of directors, and allied with other dissatisfied shareholders to control 44% of the shares. To avoid a proxy fight, the board offered to repurchase shares at fair value, paying with a portion of its investment portfolio. 77% of the outstanding shares were turned in. Buffett had reaped a 50 percent return on investment in just two years.
Assuming Berkshire
In 1962, Buffett became a millionaire with the success of his partnerships, which by then had grown to 11 entities and held nearly $7.2 million, of which more than $1,025,000 belonged to Buffett. At the start of the year, he merged the various partnerships into the single entity Buffett Partnership, Ltd., which would be his primary investment vehicle for the remainder of the decade. Buffett invested in and eventually took control of a textile manufacturing company, Berkshire Hathaway. He began buying shares in Berkshire from Seabury Stanton, the owner, who quit due to policy disagreements with the new majority shareholder. 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. 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.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, Buffett liquidated the partnership and transferred their assets to his partners including shares of Berkshire Hathaway. He lived solely on his salary of $50,000 per year and his outside investment income.
In 1973, Berkshire began to acquire stock in the Washington Post Company. Buffett became close friends with Katharine Graham, who controlled the company and its flagship newspaper and joined its board. In 1974, the SEC opened a formal investigation into Buffett and Berkshire's acquisition of Wesco Financial, due to possible conflict of interest. No charges were brought. In 1977, Berkshire indirectly purchased the Buffalo Evening News for $32.5 million. Antitrust charges started, instigated by its rival, the Buffalo Courier-Express. Both papers lost money until the Courier-Express folded in 1982.
In 1979, Berkshire began to acquire stock in ABC. Capital Cities announced a $3.5 billion purchase of ABC on March 18, 1985, surprising the media industry, as ABC was four times bigger than Capital Cities at the time. Buffett helped finance the deal in return for a 25% stake in the combined company. The newly merged company, known as Capital Cities/ABC, was forced to sell some stations due to Federal Communications Commission ownership rules. The two companies also owned several radio stations in the same markets.
In 1987, Berkshire Hathaway purchased a 12% stake in Salomon Inc., making it the largest shareholder and Buffett a director. In 1990, a scandal involving John Gutfreund surfaced. A rogue trader, Paul Mozer, was submitting bids in excess of what was allowed by Treasury rules. When this was brought to Gutfreund's attention, he did not immediately suspend the rogue trader. Gutfreund left the company in August 1991. Buffett became chairman of Salomon until the crisis passed. In 1988, Buffett began buying The Coca-Cola Company stock, eventually purchasing up to 7% of the company for $1.02 billion. It would turn out to be one of Berkshire's most lucrative investments and one which it still holds.
