Moody's Corporation traces its history back to two publishing companies established by John Moody, the inventor of modern bond credit ratings. It was first published in 1900 by John Moody, nine years before he founded Moody's Corporation. Initially called "Moody's Manual of Industrial and Miscellaneous Securities", it was later superseded by "Moody's Manual of Railroads and Corporation Securities", then by "Moody's Analyses of Investments".
