Alright kiddo, let me tell you about a very smart lady named Agnes Meyer Driscoll.
Agnes was born a long time ago, more than 100 years ago in a place called Rochester, New York. She was really good at math and science, and loved to solve puzzles. She even liked to do puzzles with secret codes in them!
When Agnes grew up, she went to college to learn more about math and science. After college, she got a job working for the government. Her job was to help make secret codes to protect important messages from bad guys who might try to read them.
Agnes was really good at making secret codes, especially in a type of coding called "cryptanalysis." Cryptanalysis is like solving a puzzle, where you have to figure out how to break a code and read the secret message.
Agnes was so good at cryptanalysis, that she became known as one of the best codebreakers in the world! She helped the government during both World War I and II, and made many important contributions to keeping our country safe.
Even though Agnes is not with us anymore, we still remember her as a smart and important woman in the field of cryptography, and look up to her as a role model for women in science and technology.
