In human context, a family (from Latin: familia) is a group of people affiliated by consanguinity, affinity, or co-residence. In most societies it is the principal institution for the socialization of children. Anthropologists most generally classify family organization as matrilocal (a mother and her children); conjugal (a wife, husband, and children, also called nuclear family); and consanguinal (also called an extended family) in which parents and children co-reside with other members of one parent's family.

There are also concepts of family that break with tradition within particular societies, or those that are transplanted via migration to flourish or else cease within their new societies. As a unit of socialization the family is the object of analysis for sociologists of the family. Genealogy is a field which aims to trace family lineages through history. In science, the term "family" has come to be used as a means to classify groups of objects as being closely and exclusively related. In the study of animals it has been found that many species form groups that have similarities to human "family"—often called "packs." Sexual relations among family members are regulated by rules concerning incest such as the incest taboo.

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."

William Henry "Bill" Gates III (born October 28, 1955 in Seattle, Washington) is an American business magnate, computer programmer and philanthropist. Gates is the former chief executive officer (CEO) and current chairman of Microsoft, the world’s largest personal-computer software company he co-founded with Paul Allen. He is consistently ranked among the world's wealthiest people and was the wealthiest overall from 1995 to 2009, excluding 2008, when he was ranked third; in 2011 he was the wealthiest American and the second wealthiest person. During his career at Microsoft, Gates held the positions of CEO and chief software architect, and remains the largest individual shareholder, with 6.4 percent of the common stock. He has also authored or co-authored several books.

Gates is one of the best-known entrepreneurs of the personal computer revolution. Gates has been criticized for his business tactics, which have been considered anti-competitive, an opinion which has in some cases been upheld by the courts. In the later stages of his career, Gates has pursued a number of philanthropic endeavors, donating large amounts of money to various charitable organizations and scientific research programs through the Bill & Melinda Gates Foundation, established in 2000.
