Written by award-winning author Megan Hoyt, this thoughtful STEM picture book biography about the brilliant architect of Grand Central Terminal is a celebration of resilience in the face of adversity, creative problem solving, and, of course, trains! There was once a place in New York City that had a tennis club, movie theater, and art gallery--all in the same building! It also had a secret passageway, a huge library, and even a ski slope. This astounding building is Grand Central Terminal, and it was the work of one brilliant man: William J. Wilgus. When William, an experienced engineer, wanted to create a new electric-powered train system, he knew he needed to house this special fleet somewhere exceptional. His grand idea of a solution? An underground multilevel train station that would become an iconic New York landmark, and one that is still an integral part of the city over a century later. Acclaimed author Megan Hoyt pays homage to William J. Wilgus and his crowning achievement in this STEM-oriented picture book biography, with whimsical illustrations by Dave Szalay.
