Clarence Stuart Houston was born in Williston, North Dakota in 1927. A year later his family moved to Yorkton, Saskatchewan where his parents, Drs. Clarence and Sigga Houston, established a medical practice. Houston graduated from the University of Manitoba with a medical degree in 1951 and continued his medical education at both University Hospital in Saskatoon and the Children's Medical Centre, Harvard University. Except for 1955-56, when he did ten months of internal medicine and two months of pediatrics at University Hospital, Saskatoon, Dr. Houston worked in the family practice in Yorkton until 1960. Upon completion of his training, he joined the staff of the University Hospital and the faculty of the U of S College Medicine. For several years he served as the Head of the Department of Medical Imaging. Although a respected diagnostician, teacher and medical scholar, he is probably equally well known in the community at large for his work in ornithology and Canadian history. Dr. Houston resigned from his University faculty position in 1995.
