Daniel Santos (boxer): Daniel Santos Peña (born October 10, 1975) is a former professional boxer who competed from 1996 to 2009.  As an amateur Santos represented Puerto Rico in international events, including the 1990 and 1992 Junior World Championships, Pan American Boxing Tournament, Goodwill Games, 1995 Pan American Games and the 1996 Summer Olympics, where he won a bronze medal in the Welterweight Division.  Santos debuted as a professional in 1996.  Santos won the World Boxing Organization Welterweight championship on May 6, 2000.  On March 16, 2002 he vacated the welterweight division's championship in order to compete against Yori Boy Campas for the vacant World Boxing Organization Light middleweight championship.  Santos defended this championship on four occasions, against Mehrdud Takaloo (in a fight where he won the World Boxing Union Light middleweight championship), Fulgencio Zúñiga, Michael Lerma and Antonio Margarito before losing it to Sergiy Dzindziruk by unanimous decision in a fight that took place on December 3, 2005.  On July 11, 2008, Santos won his third professional championship, knocking out Joachim Alcine in six rounds to win the World Boxing Association's light middleweight title.

World Colored Middleweight Championship: The World Colored Middleweight Championship was a title awarded to black boxers in the late nineteenth and early twentieth centuries.  This was the only recognized middleweight championship available to blacks prior to Tiger Flowers (5 August 1895 - 16 November 1927) winning the world middleweight boxing championship by defeating Harry Greb on 26 November 1926.

Charley Burley: Charley Burley (September 6, 1917 – October 16, 1992) was an African American boxer who fought as a welterweight and middleweight from 1936 to 1950.  Archie Moore, the light-heavyweight champion who was defeated by Burley in a 1944 middleweight bout, was one of several fighters who called Burley the greatest fighter ever.  Burley was the penultimate holder of both the World Colored Welterweight Championship and the World Colored Middleweight Championship, the only titles he held.

Shorty Hogue: Willis 'Shorty' Hogue was a boxer in California during the 1940s, along with Lloyd Marshall, Charley Burley, Jack Chase (Young Joe Louis), Archie Moore and Eddie Booker.  He had a twin brother, Willard, known as "Big Boy" Hogue, who also boxed in this era.  No complete record exists for either brother, but Shorty Hogue was once ranked #3 at middleweight by Ring magazine.  He scored three wins over Archie Moore and beat Jack Chase, Johnny "Bandit" Romero and Eddie Booker.  His win over Booker earned him the California Middleweight Championship.  Around this time, the World Championships were frozen by World War II, and most of the best middleweights of the era fought over the California title.  Charley Burley stopped Hogue in 1942, and after that, Hogue's career hit the doldrums.  Most of Hogue's bouts after this were knockout losses, including one to Eddie Booker, in which he lost the California Middleweight Championship.  There is no record of his career outside of the years 1939 to 1942, but in those three years, he went 55-1.  His only loss was to his cousin, Kole, whose record was an amazing 89-0.

Larry Estridge: Larry Estridge (born 17 June 1902, St. Kitts, British West Indies) was a middleweight boxer and the last holder of the World Colored Middleweight Championship.

Jamaica Kid: The Jamaica Kid (b. 1896 – 12 June 1938) was a boxer born Robert Buckley (a.k.a. Robert Bulkley and James Buckley) in British Honduras who fought out of New Orleans and New York City as a professional from 1916 to 1928, primarily as a light-heavyweight.  When he was based in Louisiana in the first year of his pro career, he won the World Colored Middleweight title from Eddie Palmer in New Orleans, a title he did not defend as he moved to New York City later that year.

Hank Griffin (boxer): Hank Griffin (ca. 1870 – 2 May 1911) was an African American boxer who fought some of the greatest fighters in history, including World Colored Middleweight Champion Harris "The Black Pearl" Martin, World Colored Heavyweight Champion Frank Childs and World Heavyweight Champions Jack Johnson and James J. Jeffries.

Panama Joe Gans: Panama Joe Gans was a black boxer who held the World Colored Middleweight Championship for four years, shortly before it was discontinued.  Born Cyril Quinton Jr. on November 14, 1896 in Barbados, British West Indies and raised in the Panama Canal Zone, the 5'7" Quinton originally fought out of Panama and then New York City.  He took his ringname from boxing great Joe Gans, the first black American fighter to win a world boxing title.  He found his greatest fame fighting as a middleweight at between 147 and 160 lbs, but in his early career he took the Panamanian Lightweight Title and contended for the Panamanian Welterweight Title at weights roughly between 130 and 147 pounds.

Eddie Palmer (boxer): Eddie Palmer was an African American boxer who held the World Colored Welterweight and World Colored Middleweight titles.

He fought against the best opposition the talent-rich 1910s and 20s could provide him, frequently squaring off against light heavyweights and even heavyweights. Widely considered one of the best fighters of all time, Greb was named the 7th greatest fighter of the past 80 years by the "Ring Magazine", the 5th greatest fighter of all-time by historian Bert Sugar and ranked as the #1 middleweight and the #2 pound-for-pound fighter of all-time by the International Boxing Research Organization.
