Susan Coolidge was born in 1835 in Cleveland, Ohio, but grew up in Connecticut. During the American Civil War, Coolidge worked as a nurse. Susan Coolidge loved writing stories even when she was a child, and What Katy Did is based Susan and her brothers and sisters when they were young. Susan, like Katy, was a high-spirited, imaginative little girl, who often got into trouble. Her realistic portrait of childhood set her apart from other writers of her time; instead of teaching morals, she was interested in her characters, their imperfections and the dynamics of a family. The 'What Katy Did' trilogy was a huge success.
This was one of my favourite books as a child. The children felt real enough to touch, and I fell head over heels in love with Katy. It's a book with an unstoppable heart - Katherine Rundell One of my all-time favourite books . . . It's a wonderful book, very easy to read, even though it was published in the 19th century. It's a very lively funny story Katy speaks with a charm and directness that remains as fresh as when it was written
