The world of neuroscience and social behavior lost a titan with the passing of Larry Young, PhD, on March 21, 2024, a luminary whose contributions illuminated the intricacies of mammalian social connection. Dr. Young was accepted into ACNP membership in 2009. With a heavy heart, we bid farewell to a visionary whose legacy will endure for generations to come.

Dr. Young’s journey into the realm of science was marked by an insatiable curiosity and an unwavering commitment to unraveling the mysteries of the social brain. Larry completed his graduate training in zoology and received his doctorate with Dr. David Crews from the University of Texas. His tenure at Emory University, Atlanta, initially as a postdoc with Dr. Tom Insel, and then as a faculty member in 1996, served as the epicenter of his groundbreaking research, where he delved deep into the neurobiology of social bonding [1, 2]. At Emory, he later became the head of the Division of Behavioral Neuroscience and Psychiatric Disorders as the William P. Timmie Professor of Psychiatry in 2007.

One of Dr. Young’s most profound discoveries was the elucidation of neural mechanisms underlying social attachment. Through a series of pioneering experiments, he uncovered the pivotal role of oxytocin in fostering emotional bonds between individuals [3]. His work not only shed light on the biochemical basis of attachment and empathy but also offered new avenues for understanding and treating disorders characterized by social dysfunction.

Beyond his scientific acumen, Dr. Young was revered for his generosity of spirit and dedication to mentorship. As a mentor, he nurtured the next generation of scientists, imparting not only knowledge but also wisdom garnered from years of scholarly pursuit. His impact extended far beyond the confines of the laboratory, as he inspired countless students and colleagues to pursue their passions with zeal, integrity, and fun.

In addition to his groundbreaking research, Dr. Young was a prolific author whose writings bridged the gap between academia and the public sphere [4]. His books, including “The Chemistry Between Us: Love, Sex, and the Science of Attraction,” captivated readers with their insightful exploration of the neurobiology of human relationships [5]. Through his writing, Dr. Young demystified complex scientific concepts, inviting readers on a journey of discovery into the inner workings of the brain and heart.

Dr. Young’s legacy resonates across the global scientific community. His collaborative spirit and willingness to share knowledge facilitated groundbreaking research collaborations that transcended disciplinary boundaries. His work laid the foundation for interdisciplinary inquiries into the nature of social behavior, fostering a deeper understanding of what it means to be a mammal, and perhaps what it means to be human.

As we mourn the loss of a beloved colleague and mentor, we also celebrate the indelible mark that Dr. Larry Young has left on the world. His passion for science, coupled with his profound empathy for humanity, has forever altered our understanding of the human experience. His spirit lives on in the hearts and minds of all who were fortunate enough to know him.

In honoring Dr. Young’s memory, let us recommit ourselves to the pursuit of knowledge and the advancement of science for the betterment of humanity. May his legacy serve as a guiding light, inspiring future generations to continue the quest for understanding, compassion, and love, in a world that sorely needs them all.
