UAMS Alumnus and Pioneering Transplantation Surgeon

Timothy G. Nutt

Of the hundreds of prominent graduates of the UAMS College of Medicine in its nearly 150-year history, Dr. Samuel Lee Kountz stands out for his work as a pioneering kidney transplantation surgeon. Born in the Mississippi Delta, Kountz grew up during the Jim Crow era of segregation. Despite this, Kountz became one of the world’s most respected physicians before his untimely illness and death. 

Kountz was born in the small Southeast Arkansas town of Lexa (Phillips County) in 1930, the eldest son of Rev. J. S. and Susie Kountz, a Baptist preacher and farmer, and a midwife, respectively.  Kountz attended a one-room segregated school in Lexa and, for a brief time, boarded at a Baptist school in the town. Ultimately, he graduated from Morris Booker High School in nearby Dermott (Desha County) in 1948. That same year, he applied to Arkansas Agricultural, Mechanical, and Normal College (AM&N; now University of Arkansas at Pine Bluff), but he failed the entrance examination. AM&N P

Samuel Kountz, MD (1930-1981) was born in Lexa, Arkansas and attended the Agricultural, Mechanical and Normal College of Arkansas and the University of Arkansas Medical School. He received surgical training at Stanford Medical Center and later became a faculty member at Stanford.

During his time at UCSF, Kountz performed numerous kidney transplant surgeries, discovered more effective drug techniques, and advocated for increased organ donations and funding for transplant surgery research. Additionally, Kountz and his colleague, Dr. Folkert Belzer, developed a perfusion preservation machine that allowed organs to remain viable for much longer than previously possible, a major development in the field. Under Kountz’s leadership, the Kidney Transplant Service at UCSF became one of the most respected programs in the world.
