Susan Coolidge lived in America from 1835 to 1905. She was born into an upper class family and her real name was Sarah Chauncy Woolsey. She worked as a nurse in the American Civil War and then began her writing career. Her editor was also The editor of Louis M Alcott who was having huge success with her book Little Women. The editor suggested that Susan try her hand at the same kind of family story and the five books about the irrepressible Katy Carr followed. They followed the fortunes and misfortunes of the Carr family, from childhood, through school and travels in Europe, to marriage. The books:What Katy Did, What Katy Did at School, What Katy Did Next, Clover and In the High Valley brought fame to Susan Coolidge. The titles of the first three books are a pun on the North American grasshopper-like insect, the katydid, whose noise was not only responsible for its name but inspired Susan Coolidge!
