In straightforward chapters with plenty of photos, entries in the STEM Trailblazer Bio series showcase notable inventors and scientists who broke barriers in their fields. Astronaut Ellen Ochoa profiles the titular engineer, who, apart from being the first Hispanic woman in space, has several patents under her belt and is the current director of the Johnson Space Center. Though they're a bit on the dry side, these biographies hit the major highlights of their subjects' lives, and with a broad range of topics in the series, including many contemporary women of color working in STEM fields, these will be useful starting points for students looking for research topics.
