Richard DeVos, Sr. (born March 4, 1926, Grand Rapids, Michigan) is an American businessman, co-founder of Amway along with Jay Van Andel (company restructured as Alticor in 2000), and owner of the Orlando Magic NBA basketball team. In 2011, Forbes magazine listed him as the 79th wealthiest person in the United States, and the 254th richest in the world, with an estimated net worth of USD$ 4.2 billion. (At one point, he was in the top 10 of wealthiest Americans).

DeVos was educated at Calvin College and is a member of the Sigma Phi Epsilon Fraternity. He served in the military in World War II in the United States Army Air Corps.

Books written by him include Compassionate Capitalism, "MOO", and Hope From My Heart: Ten Lessons For Life. The latter reflects his feelings after successfully undergoing a heart transplant operation in 1997. This was preceded by two heart-bypass operations in 1983 and 1992. In 1975, DeVos published a book about his success, co-authored with Charles Paul Conn, titled Believe!.

Terius Youngdell Nash (Born September 20, 1977), better known by his stage name The-Dream, is an American singer-songwriter and record producer. He is known for co-writing chart topping hits such as "Baby" for Justin Bieber, "Umbrella" for Rihanna and "Single Ladies (Put a Ring on It)" for Beyoncé, as well as for his three solo albums, Love Hate, Love vs. Money, and Love King.

Terius Nash was born in Rockingham, North Carolina and moved with his mother, Reva Nash, to Atlanta at the age of 3. He played trumpet, drums, and guitar as a child. His mother died in 1992 when Nash was fifteen years old, an event which would inspire him to write songs. He states that the death of his mother gave him a "soft spot" for women, which he credits to his desire to write songs about female empowerment such as Rihanna's "Umbrella". He moved in with his grandfather, a concrete mason who instilled a strong work ethic in young Nash. Of his grandfather, Nash recalls "He came out of a bad time for blacks in the South, but even though we lived in the hood, we had a boat, some cars and a house that was paid for. So I’ve always had a different outlook on life. There’s nothing I can’t do."

Jay Van Andel (June 3, 1924 – December 7, 2004) was an American businessman best known as co-founder of the Amway Corporation, along with Richard DeVos. He also served as Chairman of the U.S. Chamber of Commerce from 1979–1980 and later as a member of its Senior Council from 1980-1985.

He was also known for funding religious missions and conservative political causes, including the Republican Party.

Van Andel was born in Grand Rapids, Michigan. After high school, a recruiter persuaded him to enlist. He enlisted in 1942 in the United States Army Air Corps as a private and came out four years later as a first lieutenant.

Van Andel co-founded Amway with Rich DeVos in 1959.

In 1979 the Federal Trade Commission ordered Amway to stop misrepresenting the amount of profit, earnings or sales its distributors are likely to achieve with the business. Amway was ordered to accompany any such statements with the actual averages per distributor, pointing out that more than half of the distributors do not make any money, with the average distributor making less than $100 per month. The order was violated with a 1986 ad campaign, resulting in a $100,000 fine.

In 2005, DeVos launched the most expensive gubernatorial campaign in the history of Michigan, totaling more than $41 million. Ultimately, DeVos lost on November 7, 2006, to Democratic incumbent Jennifer Granholm. DeVos announced on November 12, 2008, that he would not run for governor in 2010.

Born in Grand Rapids, Michigan, DeVos is a graduate of the Forest Hills public schools and received a bachelor's degree in business administration from Northwood University. He later attended, but did not graduate from, the Harvard Business School and the Wharton School's Executive Study Programs.
