Question: In which year was this American heavyweight boxer born who was active in the 1950s through the 1970s, and was defeated by the former Canadian professional boxer George Chuvalo?
Context: George Godfrey (20 March 1853 – 17 October 1901), nicknamed "Old Chocolate" by the press of the day in the last stage of his long career, was a Black Canadian heavyweight boxer who held the distinction of being World 'Colored' Heavyweight Champion during his career.  He is not to be confused with the American heavyweight George Godfrey who claimed the same Championship 42 years after his Canadian namesake.  Godfrey was inducted into the PEI Sports Hall of Fame in 1990. Michael Gerard Tyson ( ; born June 30, 1966) is an American former professional boxer who competed from 1985 to 2005.  He reigned as the undisputed world heavyweight champion and holds the record as the youngest boxer to win a heavyweight title at 20 years, 4 months and 22 days old.  Tyson won his first 19 professional fights by knockout, 12 of them in the first round.  He won the WBC title in 1986 after stopping Trevor Berbick in two rounds, and added the WBA and IBF titles after defeating James Smith and Tony Tucker in 1987.  This made Tyson the first heavyweight boxer to simultaneously hold the WBA, WBC and IBF titles, and the only heavyweight to successively unify them. James Louis Bivins, (December 6, 1919 – July 4, 2012) was an American heavyweight boxer whose professional career ran from 1940 to 1955.  He was born in Dry Branch, Georgia.  Although he was never given the opportunity to fight for a world title, despite at one point being the number one contender in both the light heavyweight and heavyweight divisions, Bivins fought and defeated many of the great fighters of his era and won the "Duration" Light Heavyweight and Heavyweight titles.  In recognition of his achievements in the ring - among other things, he defeated eight of the eleven world champions he faced - Bivins was inducted into the International Boxing Hall of Fame in 1999.  He was also the one-time husband of Dollree Mapp, the subject of prominent Supreme Court case regarding the rights of search and seizures. Patrick Graham (born October 3, 1969 in Calgary, Alberta) is a retired Canadian heavyweight boxer.  He is not known for his skill in boxing, but for his toughness, strength, good basic boxing skills and durability.  His boxing idol was George Chuvalo.  Although he did not have Chuvalo's durability, Graham showed resilience, and the ability to compete in the sport. Elmer "Kid Violent" Ray (March 3, 1911 – May 20, 1987) was an American heavyweight boxer who fought from 1926 to 1949.  He was born in Federal Point, Florida.

Ray never fought for the title, but did fight future heavyweight champions Ezzard Charles and Jersey Joe Walcott.  In three fights with Walcott, Ray suffered a three round knockout on September 25, 1937, rebounded to outpoint Walcott on November 15, 1946, and lost the third fight by decision (April 3, 1947).  He defeated Charles on a split decision on July 25, 1947, but was knocked out in the 9th round of their rematch on May 7, 1948.  He also boxed light heavyweight champion John Henry Lewis, but was stopped in the 12th round on May 19, 1938.  In 2003, Ray made the Ring Magazine's list of 100 greatest punchers of all-time at number 44. Cleveland "Big Cat" Williams (June 6, 1933 – September 3, 1999) was an American heavyweight boxer who fought in the 1950s through the 1970s.
