    You may not know much about Thurgood Marshall. He was once denied admission to one law school because he was black. But today that same school has a law library named after him. He was a man who strengthened education rights for African Americans all over the country.

Marshall was born into a poor family in Baltimore in 1908. Like other African American students of his time, he went to separate schools that were not illegal. An 198/6 law stated that schools for blacks and whites could be “separate but equal.” But Marshall knew that most black schools were not equal. He decided to do something about it.

Marchall received a law degree from Howard University. Then he began to work at changing the country’s schools.Marchall’s strategy was to start with colleges and graduate schools, because he thought judges would sympathize with ambitious young African Americans searching for an education. In 1935, he successfully sued（起诉）the University of Maryland Law School to accept its first black student. Other cases followed, with similar results.

By the 1950’s , Marshall was ready to turn to grade schools and high schools. In 1954, he accepted the case of Linda Brown, who wanted to attend a white grade school near her home. As a result of Marchall’s arguments , the Supreme Court changed the law. It said that “separate” schools never be “equal.”In 1967, Marshall became the first African American appointed to the U.S Supreme Court.Until he retired in 1991, he supported many other civil rights bills.
