The discussion focuses on finding the earliest articles related to quantum gravity, specifically those predating Matyevei. Bryce DeWitt is highlighted as a key figure in the field, often referred to as the grandfather of modern quantum gravity, alongside John Archibald Wheeler. Participants suggest reviewing DeWitt's and Wheeler's literature for historical insights. Additionally, the 1935 work of Bronstein is mentioned as a significant early contribution to quantum gravity. The conversation emphasizes the importance of exploring these foundational texts for a comprehensive understanding of the subject.
