[7] The doctrine apparently originated in _Roberts_ v. _City of Boston_, 59 Mass. 198, 206 (1850), upholding school segregation against attack as being violative of a state constitutional guarantee of equality. Segregation in Boston public schools was eliminated in 1855. Mass. Acts 1855, c. 256. But elsewhere in the North segregation in public education has persisted in some communities until recent years. It is apparent that such segregation has long been a nationwide problem, not merely one of sectional concern. [8] See also _Berea College_ v. _Kentucky_, 211 U. S. 45 (1908). [9] In the _Cumming_ case, Negro taxpayers sought an injunction requiring the defendant school board to discontinue the operation of a high school for white children until the board resumed operation of a high school for Negro children. Similarly, in the _Gong Lum_ case, the plaintiff, a child of Chinese descent, contended only that state authorities had misapplied the doctrine by classifying him with Negro children and requiring him to attend a Negro school. [10] In the Kansas case, the court below found substantial equality as to all such factors. 98 F. Supp. 797, 798. In the South Carolina case, the court below found that the defendants were proceeding “promptly and in good faith to comply with the court’s decree.” 103 F. Supp. 920, 921. In the Virginia case, the court below noted that the equalization program was already “afoot and progressing” (103 F. Supp. 337, 341); since then, we have been advised, in the Virginia Attorney General’s brief on reargument, that the program has now been completed. In the Delaware case, the court below similarly noted that the state’s equalization program was well under way. 91 A. 2d 137, 149. [11] A similar finding was made in the Delaware case: “I conclude from the testimony that in our Delaware society, State-imposed segregation in education itself results in the Negro children, as a class, receiving educational opportunities which are substantially inferior to those available to white children otherwise similarly situated.” 87 A. 2d 862, 865.
