Dr. Aart Bontekoning is a Dutch organizational psychologist and generation expert. In the 1990s, he ran numerous experiments to study the evolutionary power of generations. Between 2000 and 2007, he developed a generation theory and a generation research methodology. In 2007, his groundbreaking generation research culminated in a PhD thesis titled 'Successive Generations in Dutch Organizations, Hidden Powers of Evolution of Cultures.' Today, many companies are using his insights. There is also growing interest outside the Netherlands, not least because his scientific generation work is unique in the world. He adopts a generational perspective to show us the evolution of how we do and think.
