Until 1960, the meter was defined by a platinum-iridium prototype bar with two scratch marks on it ( that were, by definition, spaced apart by one meter ), the International Prototype Metre, and in 1983 the meter was redefined to be the distance in free space covered by light in 1 / 299, 792, 458 of a second ( thus defining the speed of light to be 299, 792, 458 meters per second ).

In the majors, however, it was not until the signing of Robinson ( in the National League ) and Larry Doby ( in the American League ) that baseball began to remove its color bar.
