Question:
Richard Francis Dennis Barry III (born March 28, 1944) is an American retired professional basketball player who played in both the American Basketball Association (ABA) and National Basketball Association (NBA). Named one of the 50 Greatest Players in history by the NBA in 1996, Barry is the only player to lead the National Collegiate Athletic Association (NCAA), ABA and NBA in scoring for an individual season. He was known for his unorthodox but effective underhand free throw shooting technique, and at the time of his retirement in 1980, his .900 free throw percentage ranked first in NBA history. In 1987, Barry was inducted into the Naismith Memorial Basketball Hall of Fame.
In Barry's first season in the NBA with the Warriors, the team improved from 17 to 35 victories. In the All-Star Game one season later, Barry erupted for 38 points as the West team stunned the East squad, which featured Wilt Chamberlain, Oscar Robertson, Bill Russell and head coach Red Auerbach among other all-time greats. Later that season, Barry and company extended the mighty Philadelphia 76ers to six highly competitive games in the NBA Finals, something that Russell and the Boston Celtics could not do in the Eastern Conference playoffs. That 76ers team is considered to be one of the greatest in basketball history.  Nicknamed the "Miami Greyhound" by longtime San Francisco-area broadcaster Bill King because of his slender physical build and remarkable quickness and instincts, the 6'7" Barry won the NBA Rookie of the Year Award after averaging 25.7 points and 10.6 rebounds per game in the 1965-66 season. The following year, he won the 1967 NBA All-Star Game MVP award with a 38-point outburst and led the NBA in scoring with a 35.6 point per game average -- which still ranks as the eighth- highest output in league annals. Teamed with star center Nate Thurmond in San Francisco, Barry helped take the Warriors to the 1967 NBA Finals, which they lost to the Philadelphia 76ers in six games. Including a 55-point outburst in Game 3, Barry averaged 40.8 points per game in the series, an NBA Finals record that stood for three decades.  Upset that he was not paid incentive monies that he believed due from Warriors owner Franklin Mieuli, Barry jumped to the ABA's Oakland Oaks, who offered him a lucrative contract and the chance to play for Bruce Hale, his then father-in-law. The three-year contract offer from Pat Boone, the singer and team owner, was estimated to be worth $500,000, with Barry saying "the offer Oakland made me was one I simply couldn't turn down" and that it would make him one of basketball's highest-paid players. The courts ordered Barry to sit out the 1967-68 season before he starred in the ABA, upholding the validity of the reserve clause in his contract. He preceded St. Louis Cardinals' outfielder Curt Flood, whose better-known challenge to the reserve clause went all the way to the U.S. Supreme Court, by two years as the first American major-league professional athlete to bring a court action against it. The ensuing negative publicity cast Barry in a negative light, portraying him as selfish and money-hungry. However, many NBA players at the time were looking at jumping to the ABA for more lucrative contracts. Barry would star in the ABA, twice averaging more than 30 points per game.

Answer the question at the end by quoting:

Sir David Frederick Attenborough  (UK: ; born 8 May 1926) is an English broadcaster and naturalist. He is best known for writing and presenting, in conjunction with the BBC Natural History Unit, the nine natural history documentary series that form the Life collection, which form a comprehensive survey of animal and plant life on Earth. He is a former senior manager at the BBC, having served as controller of BBC Two and director of programming for BBC Television in the 1960s and 1970s. He is the only person to have won BAFTAs for programmes in each of black and white, colour, HD, 3D and 4K.
Attenborough was born in Isleworth, Middlesex (now part of west London), but grew up in College House on the campus of the University College, Leicester, where his father, Frederick, was principal. He is the middle of three sons (his elder brother, Richard, became an actor and director and his younger brother, John, was an executive at Italian car manufacturer Alfa Romeo), and the only surviving child among them. During World War II, through a British volunteer network known as the Refugee Children's Movement, his parents also fostered two Jewish refugee girls from Europe.  Attenborough spent his childhood collecting fossils, stones and other natural specimens. He received encouragement in this pursuit at age seven, when a young Jacquetta Hawkes admired his "museum". He also spent a considerable amount of his time in the grounds of the university, and, aged 11, he heard that the zoology department needed a large supply of newts, which he offered via his father to supply for 3d each. The source, which wasn't revealed at the time, was a pond less than five metres from the department. A few years later, one of his adoptive sisters gave him a piece of amber filled with prehistoric creatures; some 50 years later, it would be the focus of his programme The Amber Time Machine.  In 1936 David and his brother Richard attended a lecture by Grey Owl (Archibald Belaney) at De Montfort Hall, Leicester, and were influenced by his advocacy of conservation. According to Richard, David was "bowled over by the man's determination to save the beaver, by his profound knowledge of the flora and fauna of the Canadian wilderness and by his warnings of ecological disaster should the delicate balance between them be destroyed. The idea that mankind was endangering nature by recklessly despoiling and plundering its riches was unheard of at the time, but it is one that has remained part of Dave's own credo to this day." In 1999, Richard directed a biopic of Belaney entitled Grey Owl.  Attenborough was educated at Wyggeston Grammar School for Boys in Leicester and then won a scholarship to Clare College, Cambridge in 1945, where he studied geology and zoology and obtained a degree in natural sciences. In 1947 he was called up for national service in the Royal Navy and spent two years stationed in North Wales and the Firth of Forth.  In 1950 Attenborough married Jane Elizabeth Ebsworth Oriel; she died in 1997. The couple had two children, Robert and Susan. Robert is a senior lecturer in bioanthropology for the School of Archaeology and Anthropology at the Australian National University in Canberra. Susan is a former primary school headmistress.
