Augusto Cury, born October 2, 1958, is a Brazilian physician, psychiatrist, psychotherapist, and prolific author. He is widely recognized in Brazil as its most read author, with over 30 million books sold domestically. Cury developed the Multifocal Theory, which explores the intricate functioning of the human mind and the formation of thoughts. His research also delves into the quality of life and the development of intelligence, with a particular focus on the dynamics of emotions and thoughts. He has conducted research in Spain in Educational Sciences related to quality of life and has lectured internationally, including at BYU University. Cury holds an honorary doctorate from UNIFIL and is an honorary member of the Academy of Gifted People in Portugal. An institute dedicated to his work, the Augusto Cury's Study Centre, was established in Portugal in 2008.

Augusto Cury's central contribution is the Multifocal Theory of Intelligence. As a researcher focused on quality of life and intellectual development, Cury developed this theory independently of traditional academic institutions. The theory's primary aim is to illuminate how the human mind operates and to provide insights into how individuals can exert greater control over their lives through enhanced intelligence and thought processes. In 1999, he published "Multifocal Intelligence," detailing over 30 critical elements for developing human intelligence, including the interpretation process and the flow of psychic energy.

A significant aspect of Cury's work involves his dedicated research into the dynamics of human emotion and thought. He investigates the nature, construction, and behavior of emotions and thoughts, aiming to understand their impact on an individual's quality of life and overall development. This deep dive into the psychological underpinnings of human experience forms the basis for many of his writings and theories, seeking to equip readers with tools to better manage their inner world and cognitive processes.
