In the 19th century, playing at drawing or painting on dishes was all right for a young lady, but serious work in art was not. And when the young lady’ s family racked among the best of Philadelphia’s social families, such an idea could not even be considered.
That was how Mary Cassatt, born 1844, began her struggle as an artist. She did not tremble before her father’s anger, she opposed him with courage and at last made him change his mind. Mary Cassatt gave up her social position and all thoughts of a thousand and a family, which in those times was unthinkable for a young lady. In the end, after long years of hard work and perseverance, she became America’s most important woman artist and the internationally recognized leading woman painter of the time.
