Many Mayan scholars and archaeologists had their first research opportunity and employment under Morley's tutelage working on the various Carnegie projects. Of these, perhaps the two most notable were J. Eric S. Thompson and Tatiana Proskouriakoff. Thompson shortly became the field's most dominant figure and its uncontested expert. Together with Morley, he was most responsible for promulgating the view of the ancient Maya as peaceable astronomers, obsessed with time and calendric observations. This view became the prevailing one for the next several decades. Proskouriakoff also went on to establish a stellar career and a lifelong association with the Carnegie Institution; however, her researches ultimately provided the primary convincing evidence which later disproved much of what had been maintained by Thompson and Morley.
