Auguste Forel was a pioneering Swiss myrmecologist, neuroanatomist, and psychiatrist, whose multifaceted research significantly advanced the understanding of both human and ant behavior. He is best known for his foundational work in neuroanatomy, where he contributed to the development of the neuron theory, elucidating the structure and function of the nervous system. His investigations into the brain laid the groundwork for future studies in psychology and psychiatry, making him a notable figure in the early exploration of these fields. In addition to his scientific achievements, Forel was an early advocate for sexology, exploring the complexities of human sexuality at a time when such topics were often taboo. His controversial views on eugenics, which he later distanced himself from, reflect the complexities of his legacy. Forel's contributions to science were recognized in various ways, including his image appearing on the 1000 Swiss franc banknote from 1978 until 2000, symbolizing his lasting impact on Swiss intellectual history and the scientific community.
