A posthumous biographical profile is presented of John N. Buck, an early clinical psychologist who gained national recognition for his diverse contributions to the field. In addition to developing the House-Tree-Person (H-T-P) Projective Technique and an array of other psychological inventories, he was instrumental in establishing clinical psychology in Virginia. Buck served on the first Examining Board for Certification of Clinical Psychologists in Virginia (and the nation) and was later its chairman. He published his research in peer-reviewed journals and presented guest lectures at respected universities. These professional achievements were quite remarkable in light of the fact that Buck was paraplegic and had no college degree and only scattered formal training in psychology.
