Every field has its ‘greats.’ Those people who were there when it started and spent their lifetime and energy learning, advancing, and shaping what it is today. For our field, organizational development, also called social psychology, behavioral psychology, organizational effectiveness, or simply, ‘change,’ Charlie Seashore, Ph.D. and Edith Seashore. were at the top. Unfortunately, we lost both of them at the beginning of this year, Charlie to health issues, and Edie, we think, to a broken heart.
