Sedgwick's happy profession has been that of editing the distinguished Atlantic Monthly. Sedgwick was born and lived in New York City before transferring business and his affections to New England. Famous personages such as Dorothy Canfield Fisher, Joseph C. Lincoln, Galsworthy, Arnold Bennett, James Hilton, Nordhoff and Hall, Mary Webb are talked of, but he knew others equally interesting, such as Jim, his friend who was also a highly successful second-story man.
