Baseball Hall of Fame balloting, 1978: Elections to the Baseball Hall of Fame for 1978 introduced a new system that would continue to 1994.  The special committee on Negro Leagues had disbanded after its 1977 meeting.  Two of its members were appointed to the Veterans Committee, as part of expanding that body from twelve to eighteen members, and its responsibilities were extended to cover the Negro Leagues.  Where the special committee had elected nine people in seven years from 1971, the expanded Veterans Committee would elect two in seventeen years up to 1994, before the next reform.

Ernie Banks: Ernest Banks (January 31, 1931 – January 23, 2015), nicknamed "Mr. Cub" and "Mr. Sunshine", was an American professional baseball player who starred in Major League Baseball (MLB) as a shortstop and first baseman for the Chicago Cubs between 1953 and 1971.

Judy Johnson: William Julius "Judy" Johnson (October 26, 1899 – June 15, 1989) was an American professional third baseman and manager whose career in Negro league baseball spanned 17 seasons, from 1921 to 1937.  Slight of build, Johnson never developed as a power threat but achieved his greatest success as a contact hitter and an intuitive defenseman.  Johnson is regarded as one of the greatest third basemen of the Negro leagues.  In 1975, he was elected into the Baseball Hall of Fame after being nominated by the Negro Leagues Committee.

Veterans Committee: The Veterans Committee was the popular name of the National Baseball Hall of Fame Committee to Consider Managers, Umpires, Executives and Long-Retired Players; a former voting committee of the U.S. Baseball Hall of Fame that provided an opportunity for Hall of Fame enshrinement to all individuals who are eligible for induction but ineligible for consideration by the Baseball Writers' Association of America (BBWAA).  The term "Veterans Committee" (was composed of four committees of baseball veterans) is taken from the body's former official name: National Baseball Hall of Fame Committee on Baseball Veterans (1953).

Ray Dandridge: Raymond Emmitt Dandridge (August 31, 1913 – February 12, 1994), nicknamed "Hooks" and "Squat", was an American third baseman in baseball's Negro leagues.  Dandridge excelled as a third baseman and he hit for a high batting average.  By the time that Major League Baseball was racially integrated, Dandridge was considered too old to play.  He worked as a major league scout after his playing career ended.  In 1999, Dandridge was inducted into the Virginia Sports Hall of Fame and, late in his life, Dandridge was inducted into the Baseball Hall of Fame.

Dallas Green Monarchs: The Dallas Green Monarchs were a semipro baseball team in the Negro Leagues from 1940-1947 and again in 1953.  The team was ostensibly the successor of the Dallas Black Giants which had disbanded after the 1938 season.  The 1940s team played the majority of their games at Rebel Field while the 1953 team played at Burnett Field.  From 1940-1942, their intracity "rival" was the Dallas Wonders who they played for the city tournament in 1940.  The Green Monarchs won the Dixie Negro Semipro tournament in 1947 and advanced to the National Semipro Congress.  Chicago Cubs' great Ernie Banks' was a bat boy for the Green Monarchs and his father Eddie Banks was its catcher.  Green Monarch Hank "Donkey" Thompson went on to Major League Baseball playing for the New York Giants.  The 1953 team played in the North Texas Negro Baseball League.  But the 1954 and 1955 Dallas team in that League was the Dallas Bluebirds and the Green Monarchs appear to have been dissolved.
