Boundary changes affecting the English county of Berkshire.

Berkshire ( /ˈbɑrkʃər/ or /ˈbɑrkʃɪər/, abbreviated Berks) is both a ceremonial county and a historic county of England. The administrative county of Berkshire including the Berkshire County Council were abolished in 1998. The county is often referred to as the Royal County of Berkshire because of the presence of the royal residence of Windsor Castle in the county; this usage, which dates to the 19th century at least, was recognised by the Queen in 1957, and letters patent issued confirming this in 1974.

The ceremonial county has the same boundaries as the former administrative county, but historically the county was not co-terminous with this. The county borders the counties of Oxfordshire, Buckinghamshire, Surrey, Wiltshire and Hampshire. Historically the county included several towns to the northwest of the county (including Abingdon, Didcot and Wantage) that were moved into Oxfordshire in 1974 boundary changes. At the same time the town of Slough was moved into Berkshire from Buckinghamshire.

Warren Edward Buffett (/ˈbʌfɨt/; born August 30, 1930) is an American business magnate, investor, and philanthropist. He is widely considered the most successful investor of the 20th century. He is the primary shareholder, chairman and CEO of Berkshire Hathaway. He is consistently ranked among the world's wealthiest people. He was ranked as the world's wealthiest person in 2008 and is the third wealthiest person in the world as of 2011. In 2012, American magazine Time named Buffett one of the most influential people in the world.

Buffett is called the "Wizard of Omaha", "Oracle of Omaha", or the "Sage of Omaha" and is noted for his adherence to the value investing philosophy and for his personal frugality despite his immense wealth. Buffett is also a notable philanthropist, having pledged to give away 99 percent of his fortune to philanthropic causes, primarily via the Gates Foundation. On April 11, 2012, he was diagnosed with prostate cancer.

Buffett was born in 1930 in Omaha, Nebraska, the second of three children and only son of U.S. Representative Howard Buffett, a fierce critic of the interventionist New Deal domestic and foreign policy, and his wife Leila (née Stahl). Buffett began his education at Rose Hill Elementary School in Omaha. 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 Woodrow Wilson High School in 1947, where his senior yearbook picture reads: "likes math; a future stock broker."
