Simon Bull was born in Britain in 1958 to an officer of the British Army, which had the young boy traveling the world before he ever picked up a paint brush. By 1980, Bull earned his degree in Fine Art from Leeds Polytechnic School in the UK, having become a gifted observer of the world around him and putting it on canvas. Studying the cultural centers of Europe, the fringes of tropical rainforests, as well as classical Chinese brushwork, Bull developed his unique style and bold use of colors. He held his first one-man exhibition in Hong Kong at the age of eighteen, and his reputation has grown steadily since that 1978 showing.

His work is collected by royalty, presidents, museums and private collectors internationally, and in 2002, Bull was named an official artist of the 2002 Winter Olympics. In 2007 he was invited to create a series of paintings that celebrated the life of Muhammad Ali. Many of these works are now on permanent display in the Muhammad Ali Center in Louisville Kentucky. He has also spoken on behalf of the Muhammad Ali Center at the Vancouver Film Festival for the premier of the movie "Facing Ali".

In 2000, he won the British Fine Art Trade Guild award (Artist Print Award) for being the top selling original print artist in Great Britain. He was also short listed for the Fine Art Trade Guild’s Best Selling Published Artist Award in 1997 and again 2000.

Due in part to his own encounter with cancer in 2005, Simon Bull uses his artwork to support various causes, such as the American Cancer Society and Ronald MacDonald House Charities.

Born Cassius Marcellus Clay, Jr. on 17 January 1942 in Louisville, Kentucky, Muhammad Ali carries the legacy of one of the world’s greatest heavyweight boxers. His interest in boxing began when, at twelve years old, his bike was stolen; he wanted to beat up the thief, so he began training. A natural talent, he soon won the 1956 Golden Gloves Championship as a novice in the light heavyweight and it wasn’t long before he qualified for the U.S. Olympic Boxing Team. Ali brought home the light heavyweight gold medal from the 1960 Olympic Games in Rome. For the next decade he was an unstoppable force in the ring and in 1964 he won the World Heavyweight Championship.

1964 was also the year that Ali found inspiration in the Nation of Islam and changed his name from Clay to Ali. His spiritual and political views eventually got himself in trouble in the ring; when he refused to fight in the Vietnam War in 1967, citing his status as a conscientious objector, the boxing association revoked his championship title and suspended him from professional boxing for three years. Upon his return to the sport in 1970, Ali reestablished his place in the boxing hierarchy during the next decade. In 1971 he battled Joe Frazier in “The Fight of the Century” and although he was knocked out after 15 rounds, Ali bested Frazier in a rematch in 1974. That same year he reclaimed his championship title in the “Rumble in the Jungle” in Zaire against the reigning World Heavyweight champion, George Foreman. After countless excellent battles in the boxing ring over the next few years, Leon Spinks defeated Ali in 1978, marking the beginning of the decline of Ali’s career. After losing his heavyweight title to Trevor Berbick in 1981, Ali retired from the sport.

Since his retirement, Ali has remained involved in the sport in addition to his great philanthropic efforts. Among these are his support of the Special Olympics and the Make a Wish Foundation, as well as the Muhammad Ali Parkinson Center (he announced that he had the disease in 1984) and international relief efforts. In addition to this, the accolades have continued to pour in over the years: in 1999, Ali was crowned "Sportsman of the Century" by Sports Illustrated and "Sports Personality of the Century" by the BBC. Ali will always be regarded as one of the greatest professional boxers in the world, the one who was known to “float like a butterfly, sting like a bee.”

Muhammad Ali passed away on June, 3rd 2016 at the age of 74.
