In the late 1950s, the Institute of Personality Assessment and Research embarked on a mission to study the personalities of particularly creative scientists and artists. Researchers established categories, grouping analytical creatives together (including scientists and mathematicians) as well as artistic creatives (including painters and writers). At the intersection, there was a hybrid type: architects were seen as representing both groups. The hope was that studying architects and their creative habits could yield lessons applicable across a variety of creative fields. The researchers recorded the conversations of some of the most prominent architects of the era. This is the first time these recordings have been heard publicly.
