"As a rare female botanist in early twentieth-century America, Barbara McClintock never let other people's notions of what was proper slow her down. When she faced doubting colleagues and unsupportive institutions, she drove across the United States, climbed through windows, and even slept in her laboratory to conduct her research. In so doing, she helped pave the way for future scientific discoveries that can cure diseases and save lives--and won a Nobel Prize in the process!" --
