Ada Lovelace might not be known to everyone, but she was considered the first computer programmer 100 years before the first computer was built. She was the daughter of the poet Lord Byron, but was raised by her single mother who made sure Ada was educated in math and science. In the 19th century it was not common for women to work in these fields, but she excelled in them and worked on what is presumed to be the first computer. Ada is a great role model for children because she proves that if you're capable of doing something you should regardless of your gender. I really loved the "Enchantress of Numbers'" story especially for young girls.
