Legal rights for women have evolved in the United States since the early 1800s. Pennsylvania was the first state which had a medical school for women (1850). Other professions also began to permit women to practice most states did not admit women to practice law until the middle of the 19th century, and virtually none did before 1820. In most states, married women were not permitted to own property or enter into contracts until the mid-1800s.
In 1920, the 19th Amendment to the Constitution was enacted giving women the right to vote. It was not until 1933 that a woman served as a member of the President's cabinet (Frances Perkins, Secretary of Labor) in the Administration of Franklin D. Roosevelt.
The Civil Rights Act of 1964 prohibited sexual discrimination with regard to most employment issues. A proposed amendment to the Constitution to grant women equal protection under the law (the "Equal Rights Amendment") was passed by the Congress in 1972, but failed to receive approval from three-fourths of the states needed to ratify it in the prescribed time period for it to become effective.
Laws which exist in every state provide that women must receive equal pay for equal work, a concept which only a few decades ago was unthinkable. "Comparable worth" laws have been proposed in several states which would end the disparity between the pay of women in historically "female" dominated professions (such as teaching, nursing, and secretarial work) and "comparable" positions which are dominated by males.
Although sexual discrimination remains a problem at all levels of society, women have risen to leadership positions in government, business, and the professions, but not to the same degree as their male counterparts.
