The book "Superhero Scientists" was published in March 2021. This non-fiction text allows children to read about people involved in the fascinating world of science. The 21 chapters are full of facts, life stories and scientific discoveries, from astrophysicists to pilots, epidemiologists to vets, marine biologists to scene-of-crime officers -- the book details why they are all 'superheroes'. From conception to print the book took three years. This article explores the background behind that journey. Authors David Allen and Alex Sinclair discuss challenging stereotypes and interview MRI scientist Hamied Haroon.
